Cold Air Intake, Headers, and Catback Exhaust options.

[MrBuick (Magnum)]

Cold air Options for the 94-96 LT1 / L99.

*Note: These may not be the only places to get them, or the cheapest. Also, prices are rough estimates.

*Note: Any intake system labeled for a 94-96 Impala SS will work on the 94-96 Caprice, Roadmaster, and Fleetwood. Cars with a tow pak are limited to the stock inlet location, due to the mechanical fan, and shroud. You can convert to a dual electric setup to allow use of any Imp SS Cold Air Intake.





Factory inlet location, works with the tow pak, along with all others:

Currently produced Headers for the 94-96 LT1/L99 cars.​

*If you have a header, current or discontinued, or info that should be added or corrected, Please PM me!!

This is for Parts reference only. These might not be the cheapest locations to get them. Figure prices as a ball park. Also some offer options such as EGR, AIR, Hook-up pipes, Cats, different coating types.

*Note that some offer the option bolt in, some don't. Prices will be given for both if possible.

Header Parts of interest​

*Header gaskets, for the head flange.*


Earls Pressure Masters

http://store.summitracing.com/partd...BERL&N=700+300501+4294886122+115&autoview=sku

For Tri-Y, Budget heads, Quad-1's, or Long Tube Headers. Generally regarded as the BEST sealing, and lasting header gasket. There is a metal frame that the header and head sandwich. There is a soft Material "insert" that does the actual sealing. These inserts are replaceable, and the frames can be reused. Might be a good idea to get extra inserts incase you have to remove the headers, and the inserts won't re seal. There are other options, but these are very proven. In many cases, you only have to retighten the header bolts once, with these gaskets. Other gaskets tend to require tightening a few more times after heat cycles. *note that they are a THICK gasket, and might cause header to frame clearances on some headers, such as the Flowtechs. If this happens, you might try a thinner gasket, such as felpro's, mr gasket, percy's, etc.


Earls are not your only options. I will be adding other options as I get the correct part #'s sent to me.



*Header bolts*

I need part #'s, or the thread pitch, size, and length.


Afterburner Hook-up Pipe options from Clear Image Automotive.

http://www.clearimageautomotive.com/Other header accessories.htm

Hook-up pipes you can fab to your catback: $100

Custom "X" cross over that bolts directly to the Headers: $250

Headers​

*Note that if they are not coated, they are either Raw steel, or painted. If they are painted, the paint tends to burn off. The paint is intended to keep them from rusting in their box. Unless the headers are Stainless, it is strongly urged that you have a coating on them. And even then, there are different grades of stainless. some better than others in terms of retaining heat, and not rusting. The coating does three things. 1. Keeps the heat in the headers, to protect other items under the hood, like wiring, sensors, spark plug wires, A/C lines, etc. 2. Protect the headers from rusting. 3. Potentially help the car produce more power by retaining heat.

There are different types of headers, for different situations. Some locations require your headers to be C.A.R.B. Emissions Legal. Some retain the factory Cat pipes, and Cats in the stock location, and some bolt right to the factory cat pipes. Some require custom pipes to bolt to the factory Catback, and Some offer it as an option.

There are also different headers from a performance standpoint, such as shorty's, mid length, long tube, Tri-Y, or 4-1.

Catbacks for the 94-96 LT1/L99 Sedans.​

These might not be the cheapest prices, or only place to get them. The over the axle pipes can be modded to work on wagons, but will not bolt-in as-is.

*Note: Fleetwood owners. Any Impala SS system can be made to work. All you need to do is have about 6"-12" of pipe added to the cat to muffler pipes.

*Note: Parts for a 91-93 cars custom catback are included in "Parts of interest". Check the "215" catback note for details. Also, Tail pipe kits for the wagon are also included. If you wish to build your own custom system, or are on a very tight Budget, check the "Parts of Interest" for some cheaper options.

Parts of Interest, & Build your own Catback parts.​

"215" aka Frankenstein Catback: $215+ (realistically $250+)

http://www.impalassforum.com/vBulletin/showthread.php?t=144544&highlight=215+catback

There is the link to the ORIGINAL thread. Consists of two, 2.5" Dynomax Intermediate pipes, two, 2.5" Summit turbo mufflers, and two, 2.5" Dynomax over the axle pipes. Then you just get some flanges for the cat to intermediate pipe, clamps, some hangers, Some extension pipe to the tips, tips of your choice, and your set. The Length of the dynomax Resonator, and tip is 23.25". So you would need a combination of pipe, and tips to make up that roughly 24", which is 2 feet. The way it is set up, you would have "stealth tips". If you want the Flowmaster style, where the tip is visible along the bottom of the fender, a minor modification might need to be made to bring the pipe outlet a bit lower. You could very easily add a universal H pipe kit. Or have a muffler shop add one.

*Here is a link to the Dynomax Catback parts list. you can see the parts that were "stolen".

http://www.dynomax.com/products/cat_lookup/coupons/5034.gif

Part numbers:

WLK-45688 - 2.5" driver cat to muffler pipe
WLK-45687 - 2.5" pass cat to muffler pipe
WLK-54017 - 2.5" driver over the axle pipe
WLK-54016 - 2.5" pass over the axle pipe

SUM-630225 - 2.5" Summit Turbo Mufflers, Offset in, Offset out

*Note: You can always forget the over the axle pipes, and just have turn downs on the ends of the mufflers. Some guys do it to save weight, make it louder, save money, or to change the tone of the exhaust. Removing the over the axle pipes seams to make the tone a bit deeper, louder, and remove a bit of the snap to the exhaust. But on the flip side, if the mufflers ever thought of producing drone(that buzz like humming while you yawn), you will know it without the tail pipes. When you don't get the exhaust out from under the car, it tends to bounce back into the cabin.

*Note: For 91-93 Sedans, you can use the Passengers side pipes, a single muffler, and have a very nice single 2.5" catback. Or, you can run any LT1 catback, so long as you run some custom pipes from the manifolds/headers to the catback. You will need to modify the trans cross member by either cutting out a section, and welding a plate on the top, getting a tubular cross member(available from Clear Image Auto, among other places), or getting a 94-96 cross member, and mod the bolt holes to fit the 91-93 frame.


Build your own Catback, Muffler's: $40+ a pair

http://store.summitracing.com/egnse...904121+4294904125+115&Ns=P_SRE_DisplayPrice|0

Here are some of your other 2.5" muffler options. Nearly any one of them will work with the four "215" catback pipe, so long as the offset is not off to the same side, and the inlet and outlet are not on the same side. 2.5" offset in, offset out. Some pipe might need to be trimmed off the cat to muffler pipes, if you have a larger case muffler(longer), such as the long case dynomax super turbo's.


Spintech Mufflers: $85-$120 each

http://www.spintechmufflers.com/spintech/spintechindex.asp

order of loudest to quietest. 2.5", offset in, offset out.

Pro Shoot out's
6334 - Pro Street's

Universal H pipe kit, 2.5": $35

http://store.summitracing.com/partd...=SUM-642025&N=700+4294891681+115&autoview=sku

2.5", H pipe, 2 center sections to pipe from, aluminized steel, clamps. This looks like a great kit for add an H pipe to a 2.5" catback you may already have, such as the Hooker Catback, or the "215" catback. I have used this kit before, and it works pretty good. An H pipe isn't as good as an X from a performance standpoint, but it's much better than no cross over. It will also even out the exhaust tone, and quiet it down slightly. A great idea if you are on a budget and want a cross over. For about $50 more tho, you could step up to the X pipe kit for an existing catback, or a pypes X pipe if you are still piecing a catback together.


Universal X pipe kit, 2.5": $85

http://store.summitracing.com/partdetail.asp?part=SUM-642125

2.5", X pipe, 4 legs from the X, aluminized steel, clamps. This looks like a great kit for adding an X pipe to a 2.5" catback that you may already have, such as the Hooker Catback. Now if you are just piecing your catback together, such as a "215" catback, you would be better off to go with the Pypes Frankenstein Catback. Reason being, the 2 dynomax pipes, plus the universal X pipe kit ends up being about the same cost as Buying the Pypes X Pipe! So you would be saving yourself headaches, and time by using the pypes X pipe. An X pipe, from a performance stand point will boost power over an H, and quite a bit over no cross over. It will even out the tone, and quiet it down some. A bit more than an H will.


Pypes X pipe: $160

This the the cat to muffler section used on the Pypes Catback. 2.5", X pipe, aluminized steel.


Pypes X pipe Frankenstein Catback: $300+

Pypes X pipe from above, 2.5". Bolts directly to the Cat's. You can use your muffler of choice from the above options, 2.5" Offset in, Offset out, along with the Dynomax WLK-54017 - 2.5" driver over the axle pipe, & WLK-54016 - 2.5" pass over the axle pipe, extension pipe and tips of your choice. Check the "215" catback for details on extension & tip length. I feel that personally, this is the best budget performance option. You get an X pipe, mufflers of your choice, and tips off your choice.

*Note: check the Notes under the "215" catback


Clear Image Auto "True Flow Balance Pipe". "X" pipe: $265

2.5" bolt in cross over. bolts to the factory cat pipes, and then you fit it to your mufflers of choice. Aluminized steel, available in stainless.

Parts for the Stock Exhaust



If you are on a very tight budget, just want to change the sound or can live with roughly 75% of the gains(power, and sound) over a full catback. Here are some options for you.

Information, and pics of WHY you should consider replacing the stock pipes is to come.

*Note: The stock pipes are 2.25" from the manifolds to the mufflers, and then 2" from the rear of the muffler to the bumper.


Muffler Delete

Parts needed for *one side*. Use the stock mufflers are a template for the length, and inlet/outlet placement.

Details coming after I check my setup

Removing the mufflers, and adding "straight pipe" is about the cheapest way to change the sound, and add some performance. You might be surprised how quiet at idle it is with this mod. It is rather loud at WOT, but overall sounds is very decent. The small 2" over the axle pipes, and resonators help keep it in check. Adding headers, and removing the Cats makes it very loud.


Muffler Replacement

http://store.summitracing.com/egnse...788248+4294788249+115&Ns=P_SRE_DisplayPrice|0

Here are some stock exhaust, muffler replacements. Nearly any one of them will work with the stock catback pipes, so long as the offset is not off to the same side, and the inlet and outlet are not on the same side. 2.25", offset in, offset out. They will require a 2.25 OD to 2" ID adapter, to go from the outlet of the muffler, to the over the axle pipes. The mufflers may require a bit of pipe to make up the difference in length, compared to the stock mufflers, which are rather long. A 2.25" "tail pipe"(for each side) from say autozone can be trimmed to make up the difference. 2.5", offset in, and offset out will work, you will just need a 2.25" ID to 2.5" OD adapter, for the inlet of the muffler. which may, or may not make up the difference in length compared to the stock mufflers. For the outlet you will need a 2.5" OD to 2" ID adapter. Reason for using 2.5" mufflers, would be if you planed on doing a 2.5" catback in the future, and wanted to use those mufflers.

What is the bolt size for the flange to the cat?

 

[Thanatos]

^^^^^
3/8 or some metric 'equal' I don't remember off the top of my head.
Length is 1"




Cory, you mentioned needing p/n's for Dynomax

Their catalog only has headers for a camaro, but I assume they'll still fit the B-body.

Full length Ceramic
86130

Full length Blackjack
85130

Shorty Ceramic
87736
Shorty Blackjack

[MrBuick (Magnum)]

The ones that I think work, fit the 67-81 chevelle, and 70's camaro... but I donno which ones. there was a guy on ISSF who used them.

 

[Krzdimond]

are there other non-AIR equipped stock manifolds that will fit the LT1?

 

[MrBuick (Magnum)]

are there other non-AIR equipped stock manifolds that will fit the LT1?

probably. But the LT1 manifolds, were likely some of the best flowing manifolds, EVER. If you put them on an LO5, you will seen a power gain. The tubular manifolds from Clear Image Auto, barely gave a performance increase over the stockers. They looked better, thats for sure. You can plug the holes with a pretty common plug, IIRC. 🙂

 

[92RMSJMM]

won't disconnecting the air injection trip an MIL code?

Removed it on the last PCM retune


I know that I can plug it, but it still looks like crap, an afterthought. Would rather replace with a manifold without the tube. Didn't the 94's come without the AIR?

Thanks for the listings; they may need to be updated. Several are no longer available.

Hooker Super Comp Headers: $376

http://store.summitracing.com/partd...839039+4294908216+4294905598+115&autoview=sku

Painted. Check next listing


Hooker Super Comp Headers, Coated: $616

http://store.summitracing.com/partd...839039+4294908216+4294905598+115&autoview=sku

Shorty Header, 1 3/4", 3" collector, Steel, Coated. Bolts to the stock cat pipes.

I wanted to be clear on something: Anything that will fit on the '94-96 Impala SS engine will fit on the same year of Buick Roadmaster? When I do a search for headers for the Buick, nothing comes up, but when I switch to the Impala, many choices appear. I found this listing of the same thing you have linked above, which is a header that supposedly bolt right in with existing emissions:

Hooker Headers 2063HKR Street Force Emissions Compatible Header - $377.99/pair
http://www.hawkinsspeedshop.com/categories/exhaust-headers/products/product-785.html

[BTW I was looking for the replacement exhaust manifolds in case headers cannot be found and they only exist for the passenger side.]

Also, this seems to be the cheapest and best cat for the money:

MagnaFlow 99005HM Universal Catalytic Converter - $76.75/each

[71novaguy]

time for an update again? seems like nothing works now.

 

[71novaguy]

I can look up most of the parts myself, but I'm just trying to make sure that LT1 headers are LT1 headers. Does it matter if they are ordered for an f-body? I can't seem to find anything for b-bodys.

Also, looking at updating the heads. I'm going to have to pull the head to get the LR manifold stud out, so why not upgrade to some aluminum heads and a slightly larger cam?

 

[SpeedCouch]

Aluminum heads actually have less flow than our iron ones. It's not needed.
