Roush & FRPP X-Pipe HD

2014 Mustang 3.7 Liter V6. Exhaust mods are Roush Axle-back and FRPP Cut & Clamp X-Pipe. Also Airaid Intake and Mild 89 tune. This is my last video with the Roush. I just got my Borla S-Type Catback. So follow up in a few weeks or so! (Filmed with iPhone 6!!!) The X-Pipe did not make very much of a difference. That weird 3K rasp that Roush is famous for has been quieted down quite a bit. The exhaust note is surprisingly quieter during normal driving but screams at wide open throttle! A louder idle :) Not bad for a $170 part!
