[JDiablo]

ahh please don't tell me to put this in the powertrain section or the HMF,i need to know this answer quick...how much does the quiet core really work?i need a narly exhaust for the 400 that aint going to be to loud,i didnt even get the quad yet and the parents are gitching about no loud exhausts,lol o well does it really help that much?thanks

It works great and is really quiet compared to most other pipes. I have the QC in my HMF and it is perfect I think.

i agree with rico. it quiets it down a good amount and changes the "pitch" so the sound doesnt travel as far. it is worth the 20 bucks dude
