Great system, great manufacture, great vendor!

RiffRaff is always a win!

Fits like a factory exhaust, sounds good and installs quickly, only downfall is last tailpipe section isn’t cut to allow clamp to tighten pipes down but a couple slots cut with hacksaw and that problem is gone, did have a fitment issue with an aftermarket gooseneck hitch crossmember but that’s not diamond eyes problem

I purchased this for my 2002 Ford F250. Easy to install and my truck exhales so much more that I got gains in Boost.

Easy installation, good sound. Feels like more power and can’t wait to check mpg.

Riffraff is always excellent. Thank you Clay! Ordering was simple, shipping was fast and the kit arrived in about 3 days. Had the exhaust installed by my local exhaust guys and the fit was great and no modifications were necessary. Exhaust has a little rumble to it but not overly loud. Truck seems to pull better and I’m not worried about EGTs as much as I was with the stock exhaust. Very happy.

Truck sounds great. Install instructions aren't the best, and some exhaust hangers could be slightly longer. You'll need a helper to attach the new 4" head pipe and turbo clamp.

Everything fit right to the truck .Has great low sound .NO cab noise with this set up . I am very happy with total package n fit. Thanks

This exhaust is one of the best i ever installed .Everything fit NO problems with install .Sounds great

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.
