Customer Reviews
I ordered my down pipe and it showed up on my doorstep in a week. The install went very smooth once the turbo was pulled. I advise wearing gloves when putting the heat wrap on. It’s full of what I assume is tiny fiberglass shards. It’ll wreck your hands.
Thanks for the review!!!
This downpipe is well made and really the only right way to do these trucks. It's not a simple job to get it in there, but well worth it when you do.
Thanks for the review and look forward to receiving pictures of your install!

Let customers speak for us
The 5' exhaust with the 6" tip looks and sounds really good. The egr delete its made really nice and fits perfect and looks good.
The ccv it's easy to install it fits and looks good too. Thanks soo mutch
It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore
Not to easy if you don’t know what your doing\not mechanically inclined, but definitely worth it for the quality love the stuff!
Glad your product is on the market. I love the looks of it and the performance aspect of the intake horn. Glad I chose ya’ll. Can definitely feel the truck breathing better!!!
Overall, great kit. Wish I would have ordered the can bus plugs at the same time. A few modifications were needed to make everything work but nothing too difficult if you can tackle this type of work to begin with.
Great quality and fit
Great product sounds amazing
With my old kit that kept leaking, an abnormal seal size and changed colors as the plastic got warm. I installed the Spelab kit and fits good and have the reassurance of the locking ring to keep it in.
Looks good and very good quality
This exhaust set up is amazing and definitely worth the money! Fits like a dream and is not like anybody else’s exhaust! Thank you spelab!
