Has anyone seen any documented numbers on the gains, if any?! Or has anyone happened to of had the chance to dyno their car after installation? Or is there a post on this somewhere that I missed.

I hope someone can enligten me, as Magnaflows site states, "MagnaFlow will NEVER sell an exhaust system that doesn’t increase power over the stock exhaust system." Hmm.. :blink:

cat backs can't provide any real gains on these cars until the forward portion of the exhaust is freed up. the exhaust after the cat was designed to maintain the velocity of the gases from that point on. The forward pipes have a series of diameter and shape changes that seriously impede flow. basically the stock cat back is restrictive but it doesn't matter because the forward part is as well.

Has anyone dynoed their car with the CPE Headers and stock exhaust vs CPE Headers and aftermarket catback exhaust? I'm curious as to what the difference is.
