Subject: Re: Interior resonance / exhaust drone... by jonszr1 on 2014/8/22 15:41:27 the best way I found to keep the drone down was to extend the tips of the exhaust 2in past the rear valance. a buddy who has been doing exhaust for 30years got me to try it and the difference is amazing . might not look quite as pretty as flush mounted . but my 23 in system in cruise mode is almost as quiet as stk. my system is headers no cats 3in with x pipe and dyno max 3 in super turbos with dual exits |
