[bakes fq]

Just wonderd what sort of max bhp u can see from useing the std manifold on the evo 9 when putting a bigger turbo on ? Is any1 running more then 500 still useing the same std manifold ? Nice 1

Manifolds are good for over 550

Agreed

But aftermarket once look so much better plus you will see improved performance.. Or so I am told

 

[And@fcm]

you can port them to get a slightly better flow too

Wasn't John @ evo breakers porting stock exhaust manifolds?
