No complaints. Looks good and significantly cheaper than the VSE kit.
Look great! Can tell difference
Pretty sweet little tuner. Works great and it was super simple to set up. I’d definitely recommend it
Good fit easy to install. Looks great. Only took about 20 min to install.
Great fit on both kits
Awesome upgrade
Great product easy to install. Good bang for your buck. Will continue to purchase more products from here. Agree with everyone else on the couplers but for the price not that big of a deal.
The parts fit and they seem like good quality, install instructions could use a lot of work. Overall good product for 6.7 Cummins
I was skeptical about the pipes but they fit. Pain the a$$ to install on hot side I wish they had a install video but I just used the banks install video
Clamps seem short but they fit, put Vaseline on tubes to maneuver them easier when mounting them to the boot
These up pipes fit perfectly, no trouble at all and look awesome. I made a bracket to help support the EBP tube.
The craftsman in the parts are perfect and fit perfectly would recommend this kit 10/10 and they have excellent customer service 10/10
I have a 13 Duramax and they have the best deletes on the market. And the up pipes and down pipe are awesome! Thank you spelab.
Very happy with this product. Showed up quick and seems very well made. Fixed my annoying intermittent coolant drip and now I have the peace of mind that the fitting is secured instead of just being held in by the oring tension. Had to cut one of the small holes off of the little piece with one big and two small holes in it to clear a bracket but still very impressed. About 5k miles on it since I stalled and everything it holding up well.
Since this kit was cheaper than most I was concerned about fitment and functionality but it fit well and included everything you’d need except the bolts to secure the up pipe to the manifold and turbo. Chevy has an updated part so just order 6 of those with this kit and you’re golden (they were in stock at my local Chevy dealer). Despite other reviews saying the bracket on the intake pipe doesn’t line up at all, I found it lines up pretty well, I used a small pry bar and started the bolts by hand and it went in easily after that.
I’m not a huge fan of using a cigarette lighter for power for it, I would prefer a hardwire option. However, this functions just as advertised and I am loving it!
