QTEC35 3.50 Inch QTP Electric Exhaust Cutout Valve

It works great! Strong motor, easy to install, and switch mounting was effortless. My only flaw with the product was having to do some tweaking on the in-line fuse in order to make a complete connection. The spring in the fuse compartment needs to be a bit stronger. But other than that I love it!

I got this for my duramax, really like the idea of having a split personality truck (quiet and calm one minute, riding a bull the next). The wires they give to you to make it actuate aren’t long enough to reach the bed. The wire is very weak and will break with the slightest tug. The switch is not built strong enough to handle a bump to the side. I wish it worked better than it does

Easily install even though the instructions aren't great. Wiring is a decent gauge and the switch is good quality. The main issue that I would like to see improved is that there is no limit switch for the open or closed position. You have to hold the switch until you think it's all the way open or all the way closed. Obviously, it's easy to get it right when the car is running, but it seems like the servo will be prematurely damaged by "forcing" it open or closed.Anyway, I've had it installed on my Grand National for 2 months with no issues. I've probably run 100-200 open/close cycles so far. So far so good.

I would not buy this product again seals are terrible water enters the motor everything corrodes and ceases to work. If you're going to install this on your vehicle make sure to run the exhaust inside to keep the motor dry. Edit I have contacted customer service requesting a part I just need the electric motor and they want to sell me an entire motor and gearbox kit the motor has a part number on it why can't I get one. Poor customer service will not buy from them again.

Terrible. I purchased and not happy with quality nor fitment. My bad for waiting until winter to test fitment
