Fit like crap. As did the down pipe. I got ppe ones and no refund from spelab
I received the exhaust pipe and down pipe with in a week of the order, The packaging held together even with the weight. During assembly I ran into one problem, the bolts supplied do not fit. The down pipe holes were a 1/16 inch smaller than the holes in the exhaust flange. I was going to just drill it out, but I already had the down pipe installed, plus I didn’t own any bits good enough to churn through the meaty stainless flange on the down pipe. I did find some good grade 8 bolts in my parts bin that worked. I did not put the down pipe heat shield back in place as it was even difficult to get out, but I did have some extra exhuast wrap, so I put one more layer on the down pipe and feel confident in that. (2016 dramax, LML)
It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore
Thanks for the review and I look forward to receiving pictures of your installation feedback!

Fast shipping and it fit like it supposed to
Pipes were too short in length. Ended up buying different up pipes.
Part came in quickly and in great condition. Fit perfectly

Let customers speak for us
Fairly straight forward to install. My truck seems to be running and breathing a ton better.
Installed this billet version onto my 2019 Roush F150 recently. I wanted a cover that had the proper fluid flow vaning and fill and drain plugs to make future fluid changes easier, as I plan to renew the fluid every 30k miles. The sight glass so you can see the level and the condition of the fluid is also a great feature. I did quite a bit of research on which cover I wanted to install and saw the fluid flow issues with the square back covers, whereas this one has the proper curved design and vanes in it to direct the fluid that's coming over the top to the correct places of the differential for proper lubrication. I went with the billet one so that it's stronger than the lower priced cast version, as I keep my vehicles forever (20 years and 200k miles or more) and would rather do it right one time than have to do it again. The magnetic plugs to capture any ferrous gear wear is also a nice benefit. Installed with LubeLocker gasket.

Fits very well and is really well constructed. Also looks really good installed in the truck!
Fit, "Like a glove!"
Didn’t have an issue with the install. Instructions weren’t real clear but overall the install was easy. Parts seemed to be good quality.
Fit nice and looks great!
I love it wish I had a tuner for my truck now, but I love it thank you
Perfect fit! I love your products!
I love this intake manifold and heater delete all in one kit, I would put one on every cummins. I got the horn style without the EGR parts and it puts me at ease knowing I'm not going to be getting vaccum leaks at all the block off plates and have to deal with that pesky butterfly valve. This kit really woke up my truck, I wasn't expecting a whole lot of gains but they are definitely there. I run an aftermarket turbo setup, bigger injectors, fully deleted, straight piped (4" but want the 5"), custom tuned, cold air and manual swapped, so like I said I didn't feel it would make a difference but I felt the difference. Love this companies products and am looking to go with there sick valve cover and maybe there 5" exhaust before long.
Great price and works amazing. For the price I thought it would be cheap but it's not its great quality perfect fitment and looks amazing id recommend to anyone thinking about getting rid of the stock one. Worth every dollar
Comes with everything needed. I bought the intake so there was no need for some of this kit so if your buying a intake as well save some money and get the one without the valve delete. Quality parts id buy it again
Worked out amazing with great fitment. With the stock 4 inch downpipe this makes it a complete 4 inch straught exhaust so saves money from having to buy a full 4 inch and sounds the same and ships alot faster
very awesome good fit easy install
Everything worked perfect, the gaskets and caps were all easy to install and sealed great. The pipe was a direct fit. I opted out of the muffler and super happy. Not much drone at all on the highway. And with my tune I went from 16mpg to 22mpg very well priced kit and easy to install
