From what I've read, the plenum shouldn't make the car much louder, however, the high flow cats will definitely raise the volume.

How is this combo..
Fujitsubo exhaust, Y-Pipe and crawford cast plenum.. What would be the gains on these mods?

With an Injen CAI, Kinetix HF cats, and Crawford plenum, my car is noticably louder than stock at 5k+ rpms. It gradually gets louder and louder til 5k or so when it hits it's peak for about 2k more rpm's.
