The pipes all seem to be bent properly to avoid clearance issues, however the hangers supplied with the kit leave some to be desired.

The "T" hanger/clamp just before it goes over the rear axle was welded crooked so I had to bend it some, which wasn't difficult, just annoying. Also the round bar at the top that goes through the dual hanger setup was like 3" too long so that had to be cut before it could even be installed.

The intermediate hanger just after the trans crossmember has to sit crooked under the truck because the arm that comes off of it that goes into the hanger isn't quite made right.

The tailpipe/exit hanger/clamp isn't quite made at the right angle either. It works, but the rubber hanger has a slight twist in it now because the rod coming off the clamp isn't at quite the right angle.

None of the problems are going to cause any future issues that I can see, but it made installation a bit more difficult than it should have been.

Everything fit well but it seems like it is missing one or two hangers. I just modified the clamps and it works now. Quieter than stock we will see on the mpg.

Everything fit as it should.

Great product.

I am pleased with the quality of this exhaust . Good materials and workmanship . Probably the worst installation instructions I've ever seen but you are probably not going to install this yourself unless you have some automotive savvy anyway . The system installed solidly with no leaks and sounds good and you can't beat the price . I would recommend this system to anyone upgrading to a 4'' exhaust .

Fit and finish is great Riffraff has amazing service and fast shipping huge change in throttle response!! Worth every penny!!

Easy to install, took me about 2 hours in my driveway by myself. Good fitment, good hangers for a good price. Dropped my egt’s Around 200° while towing 11,000lbs in 106° through the SoCal deserts.

My truck is quite and getting better mileage.

Installation by myself was easy. The only thing that I would like better in the kit would be a better layout of support identification, and there location to factory support locations. System sounds good, and the performance is better.
