    Q300 vs. Perrin Stealth CBE (decibel level)

    Looking for some validation on which system is louder for a 08+ WRX sedan. I'm thinking of switching from Perrin to the Q300, but not looking to get a louder system. Anyone heard both systems?

    I've heard both on hatchbacks. Perrin is much more quite

    If you don't want it louder then why switch?
    Does the Perrin sound bad?

    No. Fitment reasons. The v-band clamp that connect Y-pipe to mid shredded my CV boot clamp and no matter what I try I have clearance issues
