My buddy is currently making currently making 413/381 to the wheels in his 99' Vette. Has a 232/236 114 cam, 85mm Zo6 MAF, ported stock 241 heads, LS6 intake, Kooks headers and 3" xpipe all going through the stock mufflers.. So how much of a gain will he get with his modified engine if he goes to an aftermarket exhaust????

Man Great Set Up , Dynomax Super Cats Go With The 3' In & Out , As To The Muffler It Up To You How Loud You Want To Go. Me I'd Go With Dynomax Or Flow Masters.

A Vette???

I'd love to see somebody run a couple of bullets or glasspacks straight out the back instead of running that goofy maze of bends and stuff.
