They are working Great
First and second day after I installed them one of them was little lazy to open
But now they both open and close fine
And also the vacuum pump motor That runs a test every minute can be annoying sometimes
Other than that I love them

got exactly what we paid for in a timely manner. Satisfied with the part, service, and price.!

Great product, easy install

Great product. Easy to install. I ended up welding a resonator to v-band clamps and insering it between them exhaust tip and the cut out. Sounds beautiful.

Nice kit, with out the premium price. A must for power strokes. Comes from over seas. Took about 10 days to receive, with good Communication along the way. Going to consider other offerings from SPELAB.

Parts are very well made and fit perfectly!

The material quality seems to be good. It definitely leaks exhaust, so the seal when the cutout is closed could be better. Since the 4" cutout uses a universal flange, it's very large and caused clearance issues for me. I had to modify it. A normal 3 bolt flange would be much better. I was unable to use the turn down due to ground clearance issues on my lowered car. It did bolt up just fine, but I had to take it off. That's no fault of the cutout. We'll see how well it holds up over time.

Once installed they sound killer! I have them on a 08 300c. It’s nice to be able to go to a silent exhaust when I am in the neighborhood then rip it open on the street. My only issue is I lose my 12v in the center console.

These cutouts are by far the best on the market, easy to install and sound great

I am very pleased with my purchase, the tubing is thicker than I expected, high quality tubing, the cutouts are very high quality and the motors operate quick and seal very well, I highly recommend the Spelab cutouts, you won't be disappointed.

Great Light kit. I have a 1500 Chevy and it looks amazing under it. I can't figure out the app yet. But they work great

I love the mechanical features of the electric exhaust cutoff. Its sick how quick the remote buttons function when you open and close the valve to the exhaust.

I haven’t installed them on my car yet, because I need to save up money to take the exhaust to the shop to get them working.

This muffler gave my car a nice deep tone and it looks amazing! It's a great quality product with a decent price.

They worked out perfectly very happy with them

Nice size looks great as shown in the picture looks to be great quality cant wait to see how it works
