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!

The PCV reroute keeps the intake dry. Big win for my 2023 truck.

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.

Solved my coolant usage issues from failed EGR.

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.

My 2009 6.4 F250 Lariat runs a lot better thanks to this egr kit, and no more check engine light now.

I'm genuinely impressed with the Suncent Exhaust Header for my E46. The packaging was exceptional—everything arrived securely sealed with zero shipping damage. Fitment was nearly spot-on, though I encountered a couple of minor hurdles. I needed to slightly adjust the engine mount bracket for a perfect fit, which was a quick and easy tweak. Additionally, the O2 bung placement required a minor firewall modification, but this is a common step with most aftermarket headers for the E46 and was straightforward to resolve. One suggestion: I recommend using OEM header gaskets over the ones included in the kit. The OEM gaskets provide a superior seal, better fit, and improved heat protection for the upper plastic valve cover. Overall, I'm thrilled with the headers. They’re a fantastic upgrade for the E46, and despite the small adjustments, the installation was smooth and hassle-free. Great job, Suncent!
