Even stock exh manifolds will work.



That is the truth... you guys would laugh if you saw how small the hole is in the turbine itself that all of the exhaust flow goes through.

My manifolds only have a 1 7/8" outlet for all 4 cylinders to flow through, and have supported 700+hp with no issue so far.

I've seen 1000hp plus on stuff a lot worse then the magnum manifolds.
