I have been running the pypes 2.5 transverse for several years. Their mandrel bent X pipe system is the "go to" for easy clean install and good clearance. I have no regrets. If planning to go up to over 450 hp, a 3'' system might be a good upgrade. Or use the pypes elec. cut outs for when you need more flow. I wanted a good sounding system, but still be able to enjoy the ride and stereo. Pypes has delivered. No drone!
