3 of 5 The clamps are totally useless! September 9, 2022
Reviewed by: Jason from South Carolina  
Good build quality. The fitment was off from driver and passenger side but the shroud around the OEM tail pipe hides it. The clamps are completely useless! As the others said, even when tightened until the point of breaking the bolts the muffler still could move. I'm going to weld mine tomorrow. Overall a decent system.

4 of 5 21 Edge installation requires some work. Not DIY October 25, 2021

Loving the sound on my 21 Edge St. Only complaint was the clamps. Disregard them and weld. This ended up being a 3 person job. Stock exhaust weighs a ton. We had to cut pipe,  then fit.. I noticed the passenger side is a little off from the drivers side. But I can deal with that.

Overall very happy with the axle back system.
The pipe clamps included were useless. Completely tightened to could still move the pipes. I used my 1/2" impact wrench to the point  of breaking the bolt and I could still twist the connection.. Standard auto part muffler/tail pipe clamps worked perfectly.

5 of 5 What I needed July 15, 2021

Bought this system a few weeks ago. I love the subtle hum I hear from the exhaust when I drive and am especially fond of the sound at acceleration -- just what I needed to bring a smile to my face!

Reviewed by: Robert from GA  
clamps that were provided did not provide proper seal, ended up welding.  installation is not truly a one man job, requires more than two hands at times and stock exhaust is a brute.  Now at first run I did not think the sound was aggressive enough, however, at the miles build up it is burning in.  I notice no drone when driving at normal constant speeds ranging from 50 to 80 mph.
