Great tunes!

2016 LML Duramax with trans tune and light tow tune. So far so good. No issues at all. Doesn’t smoke at all which I love.

Great product will definitely do more business with them

I ordered this exhaust for my 2012 duramax and it fit perfectly. No compliants. Fast shipping also!

By far the easiest most straight forward company out there will be doing business again very soon

Worked exactly as promised. No codes, no issues

Great product
Great delivery speed
Great experience
Will definitely continue shopping here.

This product is awesome. Arrived in 3 days, high quality connections, super easy to install with really easy to follow directions, truck has tons of power and sounds sweet. nothing sketchy or bad sounding as in over fueling cylinders or way to high of revving. If you have bigger then stock tires I would highly recommend trans tuning because tune 4 and 5 is rowdy on stock truck. Will definitely be buying again. Using it on my off-road only truck 😏😏

I had already purchased a EFI Live tune and EGR delete for my 2013 Duramax a year before and it was perfect. There never was a question about who I wanted to deal with when my little 4 cylinder diesel Cruze’s DPF plugged and went to limp mode. These folks could have hung me for a new tuner but they were honest enough to tell me that I just needed to purchase the tune file since I already had the tuner for my Duramax. Not being the most tech savvy guy, I needed walked through getting the tuner updated and the file downloaded. These folks ALWAYS answered their phone or responded immediately to my emails. Best customer service I have ever dealt with…hands down! I would recommend them to anyone every day of the week. Thank you for getting my little 60 mpg buggy running strong again.

Fit my 2012 Ram short bed nicely, easy install, cut about 1" off to get everything to line up, have an extra clamp & section of pipe left over since I have a short bed

These guys are sharp and willing to go out of their way to make sure all your questions get answered and you are completely satisfied. Wouldn’t hesitate one bit using them for your tunes. Thanks tune supply
