My 3rd Magnaflow install; quality continues to impress! Easy to install and everything lines up. The included exhaust clamps made quick work ensuring no leaks. Was a bit worried there would be drone in the cabin but there is none at all. Overall, very happy with quality and sounds amazing!

We took a lot of time trying to piece the connections together as the drawings were not that clear. The attachment of the left pipe hanger was very vague. The pictures didn't help all that much. The bends and placements of the pipe did fit well. We inadvertently installed the muffler upside down but I don't think that mattered And the spare tire can no longer fit where it was originally - which would have been a deal-breaker if I had known that earlier. The sound was louder than I anticipated making my truck sound like a sports car. The drone becomes very loud when driving uphill. I was hoping for a full sound, not a loud gravel-y sound

Was a bit of a pain to install but that's partially due to the fact that I didn't have all the right tools. But also the midpipe was not bent enough to clear a certain area but once I worked past that and got it installed it sounded great and I love it!!! Next stop, downpipe!!!

Exhaust pipes don't line up with the factory exhaust valance. Needs to have additional exhaust tips custom made to exit properly out of the valance.

I would have given it five stars across the board but the package was delivered to my home and I brought it to the mechanic shop. When they open the package there was no hardware. No hanger straps and no clamps. Just the pipes were in the sealed carton. The job would have taken about 40 minutes to complete but I had to wait over an hour for the missing parts to be purchased from the auto store and delivered. So the pipes are great, they look and sound great, but there was a serious lack of quality control in packaging.

This exhaust pairs perfect with Stage 3 intake manifold, Stage 2 Air intake and Tune upgrades I did. It gives a nice growl to the car but not obnoxiously loud to the point of setting off car alarms as you drive by. The hardest part is cutting off the stock exhaust as the clearance between the top of it and heat shield are minimal -see pic. I used a 6" cut off wheel on my angle grinder to cut off as much of the pipes as possible then used a hand hacksaw for the rest. Some Tips for the install: Marking the cuts: Lightly clamp the magnaflow pieces together then put it on jacks under car and align it to the hangers then mark the spot. Cutting stock one: If using 6" cutting wheel then start the cut between the two pipes and go up as far as possible then from that point cut outwards of each pipe. Removing/Installing old/new exhaust: Use jacks to hold in place and support the weight while doing either. Stock exhaust: weld a sleeve that extends roughly 6" before and after the end you cut off. Now you can swap between the two if needed (takes 10 mins to swap) or keep it as a backup. Follow the rest of the directions that come with the exhaust. Take your time and use neccessary safety equipment when doing this easy DIY.
