Hey guys,does anybody have this on their P5??How does it sound??See I have a cat-back right now which I thought is a Magnaflow because when I looked at the pipe up close and nowhere did it say "Magnaflow", and I looked on their website and even their univeral canisters says "Magnaflow" on it.So I figured the guy who sold it to me lied and gave me Magnaflow stickers to "cover up his tracks".I mean the one I have sounds great but I don't know if it's street legal?So I was thinking of up grading to the Hi-Power.For the P5,it says "rear section only",does that mean the just the muffler??
