As the title says i have a couple of questions about the exhaust for my motor. I’m wondering how much research has been done on the flow of the exhaust and where the restrictions are. I know replacing the exhaust is obviously the best way but I’m wondering if there are restrictions before that as a cat back exhaust won’t see full potential if the exhaust manifold is restrictive. I’m also wondering if I can take a pair of aftermarket headers or the throttle body from the camaro, which has the same motor? Sorry if there’s already information about this, I’ve googled and haven’t found anything. I may be wording it wrong but dropping links or where to navigate the forum to find the info is much appreciated.
