Key Features & Build Details

  • 4" Mandrel-Bent Exhaust Tubing – Maintains a consistent internal diameter throughout the pipe to reduce turbulence and improve overall exhaust gas evacuation from the turbo.
  • Dual Stainless Steel Material Options – Available in T-304 stainless steel for maximum corrosion resistance or T-409 stainless steel for a more economical option while still maintaining durability.
  • Direct Replacement Design – Built to replace the factory catalytic converter and DPF section, maintaining proper routing under the truck while using OEM hanger locations.
  • Full Emissions Section Removal – Eliminates the restrictive catalytic converter and diesel particulate filter assembly commonly known to create exhaust backpressure on tuned trucks.

Performance Benefits

  • Reduced Exhaust Backpressure – Removing the factory DPF and catalytic converter significantly improves exhaust flow, helping the turbo operate more efficiently.
  • Improved Turbo Response – Less restriction after the turbo allows exhaust gases to exit faster, which can help improve turbo spool characteristics.
  • Lower Exhaust Gas Temperatures – Improved exhaust flow can help stabilize EGT levels during heavy load or towing situations when paired with proper tuning.
  • Supports Performance Tuning – Provides the necessary exhaust configuration required for off-road race tuning on L5P Duramax trucks.

Installation Notes

Direct-fit exhaust section designed to replace the factory catalytic converter and DPF assembly. Installs using standard exhaust tools and factory mounting locations. Professional installation is recommended, and ECM tuning is required to prevent emissions-related fault codes after installation.


Frequently Asked Questions

Q: Will this fit a 2019 or 2024 L5P Duramax truck?
A: Yes. This pipe fits 2017–2025 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD pickup trucks equipped with the 6.6L L5P Duramax engine.

Q: Does this fit Cab & Chassis trucks like the 3500HD, 4500 or 5500?
A: No. Cab & Chassis trucks use a different exhaust configuration. This pipe is designed specifically for pickup models only.

Q: What is the difference between T-304 and T-409 stainless steel?
A: T-304 stainless offers higher corrosion resistance and is preferred for trucks operating in wet or salted environments. T-409 stainless is more cost-effective while still providing solid durability for normal use.

Q: Is tuning required after installing this pipe?
A: Yes. Since this pipe removes the factory emissions components, proper ECU tuning is required to prevent check engine lights and ensure correct engine operation.

Q: Does the kit include hardware?
A: The pipe is designed to integrate with factory mounting points and exhaust hangers. Installation typically reuses factory clamps and mounting locations depending on the existing exhaust configuration.

Ten Stars
I only use the left two colors but I expected that since I wasn't sure which one(s) would work. They are a great concealer of dark circles. I use the lightest one on the bottom and then touch up with the darker of the two. They don't look caked on and, in fact I can wear them alone without any foundation or powder on my face! And, they lay on top of the fine lines, hiding them somewhat. The brush is great for applying. I have tried many concealers and this is the the best by far.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!

Great value and very practical
Style: SPF 50, Size: 8 Fl Oz (Pack of 6)
This sunscreen is a great value for the price. The SPF 50 protection works well and the lotion applies smoothly without feeling too greasy. It absorbs nicely and provides good coverage for outdoor activities. I especially like using these bottles to refill the sunscreen dispensers at my Airbnb for guests. It’s convenient, reliable, and affordable when you need multiple bottles available. Overall, it’s a solid everyday sunscreen and a very practical option if you need good protection at a reasonable price.

good price for good product. applies well, shake and store upright
Style: SPF 50, Size: 8 Fl Oz (Pack of 1), Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I believe it is equal to the name brands It is 50 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning. It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It is thick and goes on with a non shiny, non greasy, solid thick feeling which is what we need for it to stay on as long as possible. It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen. It is a good product and offers burn protection to me in some clear-sky strong sun uses. Reapply after entering the pool water or swimming laps and after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies). I reapply often and I still get tanned but I do not want to burn.

Survived the sun like a pasty legend
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I bought this sunscreen because I’m basically a human marshmallow — one hour in the sun and I’m toasted. This Amazon Basics Sport SPF 50? It’s like armor for the pale and easily crisped. I slathered it on before a full day of hiking, sweating, and pretending I enjoy direct sunlight, and guess what? No burn. Not even a pink glow. Just victory. It goes on smooth, doesn’t feel greasy, and somehow stayed put through sweat, water, and my dog licking my arm. It’s fragrance-free, which means I didn’t smell like a coconut smoothie or a chemical spill — just clean and protected. Pros: • High SPF that actually works • Sweat and water resistant — like, impressively so • No greasy residue or weird smell • Affordable and comes in a big ol’ bottle • Didn’t turn me into a lobster (the bar is low, but still) Minor feedback: It’s not fancy or trendy, but honestly, I’m here to not burn — not win a skincare award. Also, it takes a bit of rubbing in, but once it’s on, it’s locked and loaded. Final thoughts: If you want solid sun protection without the drama, this stuff delivers. Whether you’re hiking, swimming, or just trying to survive summer, it’s a reliable sidekick. Would absolutely buy again — my skin demands it.
