Bastuck cat-back vs. Bastuck w/downpipes vs. AE full exhaust

jahmed78 · 11-02-2010, 08:06 PM

I'm looking for at least some performance boost, a nice growl, and no headache with emissions.

I'm specially curious about Bastuck paired with stock downpipes vs cat-less downpipes. How much sound difference? How about emissions? Big performance diff?

Thanks!

Beside with this- We did designed our system with the most smoothest pipes which also includes by removing the stock resonators which causes a bit bottle neck through the system. We did decided that everyone would appreciate the most possible performance, best sound, and simple installation. On this choice. Then you really can have your cake and still eat it for a very long time.

Let me know if you have any other questions.

Just to add on this- We do have many owners running the most powerful cars with our system.
