Need some advice. Right now I'm running a 2.75" exhaust with UltraFlow muffs. I think it's too loud and it's got the dreaded drone at 2000ish RPM part throttle. Was thinking of replacing the y-pipe with a 2.5 incher. I know ATR and torque tech sell just the y-pipe.

Question...will the smaller diameter y-pipe make the system quieter and lessen the drone?:confused:
