Headers/Exhaust/Performance

I recently bought an 05 C6 with a Manual Transmission. I am considering Headers and Modified Exhaust. Any recommendations on the the best system? Also, does anyone have the power and performance increase numbers. THANKS

I'm running the Dynatech SuperMAXX 1 7/8 headers and the Corsa Sports. Great sound and no drone. If I remember, my numbers after the tune and dyno were 350 rwhp and 340 rwtq. Since then I added heads and cam and my new numbers are 443 rwhp and 399 rwtq.

Welcome to the forum!

There are many different exhaust setups to chose from, try doing a search and you'll find more than enough information.

Any of the major brands will be fine, the performance differences between them are negligible. Do have them coated. That will reduce the chance you'll get catalyst low efficiency codes as well as helping to keep engine compartment temperatures down.
