Hey guys, how do these stock up against the Plazmaman plenums? I'm undecided on whether I want to run a FFP as I can't see any definite power gains and there have been several cases of where power has gone backwards, which is why I'm cautious. Apart from easier access to some components, what would your advice be? The car is a street legal, which sees occasional track/drift days.
Also, can it come in a raw finish for a stock look?
Thanks guys.
