Perfect fit! Heavy metal pipe and perfect welds! Easy to install!!! Would recommend!!

I bought my son’s truck without cats and replacing them in a shop was way too expensive. We bought these on the recommendation of his auto shop teacher! His teacher helped him install them in class, they are a great fit and his truck is so much quieter. No more gas smell or waking the neighborhood on his way to school and work! Would definitely recommend!

Flanges was not quite the right angle, but really torque them down and got them to seal up ,crossover pipe not quite long enough to use the exhaust clamp provided Ended up welding that joint all in all check engine light Didn’t come back on , notice a difference in how truck idols and accelerates so far so good

i could not use it due tomy van was longer,sucks cause they dont have it formy van and it was a great deal came quick. i almost put it on an took to a muffler shop.ALMOST.IT DOES NOT COME WITH ALL THE BRACKETS NEEDED FOR THE MUFFLER SUPPORTS

This does not line up with properly anywhere! After attempting replace stock clogged cats and breaking 2 bolts I find out that this doesn't even line up properly with the stock assembly. The ends are not exactly the same on either end so now I have to spend more and get adapters, cut the ends off the old pipes so they connect properly, cut the pipes I just ordered AND buy connectors to fit the pipes together on either end. Also the entire thing is about 1.5-2 inches shorter then it needs to be. If it wasn't a massive pain to return I would in a heartbeat.

It’s fits perfectly on my 03 GMC Yukon .My car couldn’t pass emissions until I purchased this item . I changed all of the sensors and tried gas treatments non of those thing worked until I changed my exhaust

Fit perfectly. Needed a new gasket O-ring for driver side piece where it meets with the collector as well as the triangle shaped gasket . $10 and done overall well worth the money saving thousands!!
