🚗 Enhance Your Ride's Performance with the Roush 421145 Exhaust System Review

Starting with the removal of the muffler Roush offers a much better sound. This is a lower tone. Removing the silencer also made it much easier for me to remove it. However, don't expect any explosions or pops like in most of the videos.

Better than expected. We've done a lot of research and Roush Axle Back seems to have the most consistent reviews. We listened to many audio videos. The video does not show this. Sounds a lot better than we expected. Very easy to install.

The sound of this exhaust is AMAZING, no video here captures it, you have to hear it for yourself, the sound would be an orgasm for any car enthusiast. The only tricky part is removing the old muffler when it's done, although it's easy. That's the difference between day and night. 11/10 would definitely buy again.

My husband's 13 Mustang sounds fantastic with these! Installation was easy, easier if you lift the back. Loud, especially when accelerating. When you drive the car and drive through inertia, it is not noisy at all. It's like a purr when it's just idling. Highly recommended, worth the money!

Great exhaust! Very quick and easy installation. If you're having trouble getting them off the hooks, use a little spray lube/grease, it makes things a lot easier. The exhaust is great at normal speeds, there's almost no hum but at 3000rpm it gets raspy but once you get over that it goes back to normal. Overall great purchase and great exhaust 5 stars

This system looks great! And it's loud! I like that. It has a great rumble at idle and at higher revs it sounds like an exotic car. At freeway speeds I noticed a slight hum, but not too bad. After a few days I got used to the sound and love it even more! Tunnel, oh my gosh, drive through the tunnel, roll down the window, put in some gears and enjoy the great sound! It has such a cool popping sound when braking. One cool thing I noticed is I get 4 mpg more! Even with hard driving and hitting…
