Fast shipping and super smooth installation. Freed up so much restriction on my 2015 Chevy 3500HD. Sounds healthy, truck breathes much better, and mpg improved noticeably on the highway. Solid product from SuncentAuto!
Wanted to share a quick video of the pipes before I get them on. This is the T-409 stainless version, and as you can see, it looks great. Much better than the old aluminized pipes I had. It's a simple, straight-through design that should remove all the restriction. I can't wait to install it. If you're looking for a simple, budget-friendly option, watch the video to see the quality.
Got this 4-inch downpipe-back kit for my 12 GMC Sierra. The performance gain is night and day! Spool-up time is way faster, and my EGTs dropped significantly when hauling my heavy trailer. The T-409 stainless construction feels heavy-duty. Paired it with a proper tune and the truck runs smoother than ever. Highly recommend for any LML owner!
Couldn’t be happier with this downpipe. My cat got stolen more than once and I was done paying big bucks for another converter. This setup saved me cash and gave the car a way cooler sound.
This is hands down one of the best upgrades I've done for my '06 6.0L Powerstroke. With the exhaust restriction gone, the turbo spools up way faster, and the throttle response is significantly sharper. The best part is seeing a noticeable drop in my EGTs, which gives me peace of mind for engine longevity. I even noticed a slight bump in fuel economy on highway trips, maybe 3-4 MPG better.
