      Sounds ok

      Super easy install. Its sounds like the price. It was on the cheaper side of the axle back. It def sound good but doesnt have that throaty crackle i was looking for. Also 2k rpm droans pretty loud.

      Upgraded to these after having flomaster American thunder axlebacks. Big difference! Then paired them with an off road x-pipe,lets just saying my girlfriend talk a lot of noise to camaro as owners every chance she gets now. Head turner!!

      LOUD. Some Fitment problems.

      I installed these mufflers and they are loud! Realized when I opened the box that they were pretty much a straight pipe axle back setup. Tone is good. Some things I didnt like too much was the shipping box was received ripped up, the mufflers had the ability to slide back and forth in the box, making it poke holes in the box, almost loosing my shipment. Also, fitment of the mufflers were pretty dang off. You will need to bend the hangers in the right place and might take a few tries to line it up right and some muscle. Total install time for me with a air ratchet and impact was about 2 hours including set up and take down. One of those hours alone are removing the stock mufflers which are a PAIN. Save your self some trouble and loosen the clamps after the H-Pipe and lightly jack up the over-axle pipe to make clearance to add and remove the mufflers. ( or take them out completely, i didn't do this). Lastly, use the old factory clamps. The ones included are not very good. There is Drone. I am sorry to say. Pretty loud volume in the cabin. Other then that, can not complain about the price.

      Good Price!

      Identical to Roush mufflers and at half the price. Had to reuse old clamps as ones in kit did not fit but was an easy fix.

      Great product for the price.

      I purchased the nxt step axle back 5 years ago before AM had them in their inventory. Being so low cost I had my doubts about them but they have held up great, look nice and sound like Roush mufflers but at half the price. I highly recommend them to anyone who wants a straight through axle back and is on a budget.
