I couldn't take it anymore!
My solution to fixing the soot buildup issue on my Regal GS.
It wasn't cheap and it sort of solved two problems (3 if you count weight) at the same time.
I sketched up a plan and submitted it to my local muffler guy. I said the suitcases have to go, so with a swift slice with the sawzall the whole assembly came down as one giant, heavy unit.
The '14-up GS comes with a 2-1/2" to 2" y-pipe. They welded and bent 2-1/2" to the back that finishes with flush turndowns in the factory location. I left the after-cat resonator intact.
In hindsight I should have left the metal natural but they talked me into high-temp matte black to look more stealthy. I'll put up a better pic when this blast furnace heat subsides.
Soooo,,,,,
1. less weight (~50#)
2. no more soot on the ornamental finishers.
3. better sound with some authority. Not too loud and you can really hear it on GS mode downshifts. Not ricey in any way which is what I was trying to avoid, but a deep rich tone.
Happy so far in the short ride home. The craftsmanship is top notch and the price reflected that.
Funny thing is the shop owner asked why I didn't want the pipes through the slots. When the car was back on the ground I showed him why.
