Cats or no cats? Hmm...
I'm thinking about Stainless Works headers to go with my previously installed Stainless Works cat back system. But what I need some help on is whether I should get the high flow cats with the headers or not. I don't have any emissions inspections to worry about here.
Has anyone heard both? If so, how much of a sound difference is there (tone and volume wise)? Is one going to be harder to dial in on a dyno than the other? This might be a dumb question, but would each setup require a different plug than the other? I was originally thinking TR7ix.
Other mods already installed: CAI, 2.5 upper, ID850 injectors and tuned for all those.
I guess I'm not really worried about how loud it is Any input would be appreciated. THANKS!
