Extrude Honed Exhaust Manifolds

[Trusty89]

It seems like there has never been any talk of this here. Has it been tried and found wanting or are the exhaust manifolds so good it wouldn't help?

would'nt know the stock exhaust is pretty good i changed my mufflers with a strait thru design and i liked the sound but it lost power . so i put me stock ones back on . i have no cats no air filter or silencer and 176.000 miles autolites and run 93 octane all the time . plus my trans shifted funky without stock mufflers now it shifts a lot harder. pretty much just get rid of the converters. my car smokes my buddys 95 atx and it has a tb lpm sho shop 80 mass air sho shop y pipe 60k and 52.000 miles and k@n plus all new sensors . PRETTY MUCH WORK ON THE INDUCTION SIDE AND GET SOME CAMS TO GET SOME VOLUME THRU FIRST.

Search... you'll find this hashed over. There's no benefit

Theres no benifit, however the exhaust manifold collectors can be bored out slightly for a gain. Talk to SHO dude (Doug Lewis) for more info.
