Customer Reviews
Nice finish on them, and they are much bigger than stock, a higher quality exhaust gaskets would set these over the top. Drivers side leave loose until all the bolts are in, the bellows have to flex some. I highly recommend them, they are a nice upgrade. My complaint is the supplied bolts were of no use, the down pipe I also ordered don't fit properly with these up pipes, I did modify and restrict the down pipe a little, (still near as much as stock)
I did reach out to customer service, talking to a human would have been even better, they did refund the down pipe, I would honestly give it another try if they make it more straight. So yes I recommend there products and since have purchased the y bridge kit, and the fuel filter adapter.
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!
Took a little bit of fitting and some fabrication but it works great

Let customers speak for us
Awesome people and products an I will be using yall on all my builds I got three more trucks to do maybe put some instructions in for none mechanical people would be very helpful I bin working on disel hevy equipment for over 30 years I know where everything gos an how it works just put 2016 engine in 2012 truck just had few changes but all good
Quality product, carefully packed and quickly shipped. Very happy customer here.
I was surprised when I removed the DPF/SCR and replaced it with a straight pipe with a high flow muffler… and it was quiet. But I don’t have to worry about getting pulled over. Easy install, very straightforward. Would buy again. Shipped fast! But if you want louder pipes, consider the straight pipe.
Great product, well made, fit is perfect. Hardware sent is a little short in my opinion so I reused factory hardware. Turned out great.
Great product and comes with everything you need.
In my opinion best bang for your buck and very trustworthy company and had in stock
Great kit but I like the black bracket for the water pipe and exhaust temp sensor.
The installation is easy and smooth.
They make the parts affordable thank the lord, got the website from my mechanic but he never tried them yet- I gave them a shot now I get it
I’ve bought this part two times now for different trucks and it works great highly recommend!
The exhaust sounds amazing. And very easy to install. Only complaint would be packaging. UPS destroys the box when delivered, if there were better Cushioning within the box, less likely to be damaged.
Great Fitment and Fast shipping. Highly Recommend!
The expansion tank fit excellent and looks great. Functions as it should.
All parts arrived promptly and packed well. Installation was smooth and trouble free except for the tube style heater which would not thread into the new intake elbow. The provided plug threaded in fine so will have to revisit that issue before winter.
Overall I was very impressed. Pricing was great, everything I needed was provided. Quality of the parts was good. I would definitely recommend this package when compared to others.
