Review on Upgrade Your Vehicle with the Roush 421127 Exhaust Kit for Enhanced Performance by Justin Steele
Purrfect sound, easy installation.
I used to have a Dynomax and a Flowmaster 40 but they really bark! I like the sound. They're very loud at full throttle, but very quiet when cruising and don't hum on the freeway. I have a 2013 Mustang 5.0 convertible which isn't as quiet on the road as the coupe, but the exhaust is still okay at highway speeds. They were VERY easy to install. The whole job took less than an hour on jack stands on the garage floor. Two people could help remove the old mufflers from the hangers, but no help is needed. In addition, it is necessary to loosen and shift the panhard rod. But everything is simple.
