Up-pipes and down-pipes – what do they do?

Up-pipe is a piping that connects the exhaust manifold with the turbo. Exhaust gases enter the turbo from the up-pipe. Down-pipe is a piping that connects the turbo with the rest of the exhaust pipe. Exhaust gases leave the turbo from the down-pipe. For those looking to enhance their Duramax's performance, consider our LML delete kit and Duramax delete kit for optimal results.

Lmm up pipes

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.

Nice product at a good price $... 2016 LML

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)

Lml down pipe

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!
