I can tell you the flowmaster hushpower sounds great. Really deep deep bass sound. There is some interior resonance at low rpm. Boderline intolerable for long stop and go drives. No problem on the highway. Removing blocking off the sound tube helps a little. Pretty happy with mine. Considered the roush axlebacks. Sounds good more of a hollow sound and no low rpm interior resonance as much as the hushpower. Try to hear them in person vidoes dont do it justice. I would've gone roush but the hushpower is so deep. Easy install, fitment is good. No issues during the install. There are hanger bracket that i removed and put onto the mufflers instead of just sliding them into the hangers. It was easier that way. There just wasnt enough room to just slide in. If you like flowmasters and generally how they sound you'll prob like them.
