DESCRIPTION
Product Overview

- This High-Flow Intake Elbow &EGR Delete Kit completely eliminates the leaky EGR cooler while upgrading the necked-down factory elbow to a smooth, mandrel-bent high-flow pipe. It bulletproofs your engine while opening up the air path for instant throttle response.
- Premium Billet Construction: CNC-machined anodized black aluminum blocks off the intake ports perfectly. Features premium,leak-free seal under high boost.
- Lower EGTs &Coolant Temperatures: By completely bypassing and deleting the hot EGR cooler, you drop EGTs and take the thermal load off your truck’s cooling system.
- Quicker Turbo Spool-Up: Freeing up your intake restriction allows clean, fresh air to flow without turbulance. You'll feel a crisper, more instant throttle response when pulling heavy loads.
- Better Fuel Mileage : When your diesel doesn't have to re-burn dirty exhaust soot, combustion efficiency peaks—giving you more miles out of every tank.
FAQ
Q: Will this High-Flow Intake Elbow connect to my aftermarket cold side intercooler pipe?
A: Yes. Our High-Flow Elbow is designed to match the factory connection specs. It will fit perfectly with stock cold side pipe or any aftermarket intercooler pipe designed to connect to the factory intake elbow.
Q: Where does my factory MAP sensor go after deleting the EGR?
A: It stays right where it belongs. On the LLY and LBZ engines, the MAP sensor is located on the intake bridge, not on the EGR components themselves. Our kit is designed to fully clear and accommodate the factory MAP sensor bracket, meaning you don't have to splice, extend, or modify any of your sensor's electrical wiring.
Q: Which exhaust upgrade do you recommend?
A: To maximize your EGR delete, we highly recommend pairing it with our 4" or 5" DP-Back Exhaust Pipe. This straight-pipe upgrade replaces the restrictive factory CAT and muffler, dropping EGTs by another 150°F, unleashing instant turbo spool-up, and giving your Duramax that deep, classic growl.
Q: Do I need to replace my passenger-side Up-Pipe when deleting the EGR?
A: Yes. stock up-pipe has an EGR branch. Simply blocking it off traps exhaust pressure, which eventually cracks the fragile metal bellows (flex section) and causes a major exhaust leak. Replacing it with an EGR-delete Up-Pipe eliminates this failure point permanently.

Verified buyerRunning between three rig sites every week, was burning through DEF in about 2 weeks. Getting 6 weeks per jug now. Regen lockouts used to cost me half a day in the field, that's done with.
Chris D.
Verified buyerGot four trucks on the ranch, did this one first to see how it'd go. Eight months in, no codes, pulls hay like she's new again. Other three are getting done before winter.
Travis M.
Verified buyerTowing the boat down to the Keys used to kill me at 11 mpg. Got 15.4 last trip, same boat, same route. Pipe looks stock from the outside, none of my buddies even noticed it's gone.
Mike R.
Verified buyerHauled my horses from Fort Worth up to Amarillo last month, got 17.8 empty on the way back. Was running around 13 before. Pulls a lot better up the grades too, didn't expect that part.
Jason T.
Verified buyerUsed to go into regen every 280 miles when I was loaded down, now I'm pushing 580 with no regen at all. EGTs run way cooler too pulling the skid steer. Wish I had done this sooner, honestly.
Brandon L.
Verified buyerBought it used and the previous guy had wiped the delete history clean. Got everything put back the right way, ran the protocol, passed smog first try. Truck finally drives like it should.

Fitment guaranteed or refundGot questions?
The stuff that keeps you up at night before you commit. Answered in plain talk by guys who actually wrench on these trucks.
A full mandrel-bent stainless DPF and CAT delete pipe, EGR block-off plates and gaskets, DEF delete components, all mounting hardware and clamps, and your preloaded tuner with the custom tune for your VIN. We don't ship anything you don't need, and we don't leave anything out that you do.
No. The custom tune disables the codes the deleted hardware would otherwise throw. Dash stays clean. If a real fault code pops up after install, call our line and a tech walks you through it. Usually it's a sensor that got unplugged during the wrench work, takes 5 minutes to sort out.
We pull your VIN before we ship. Engine, year, trim, cab config, all verified against the kit. If it doesn't fit your truck, you send it back and we either ship the right kit or refund you in full. Fitment is on us, not you. That's why we call it a fitment guarantee.
Most of our customers do. Average install is 2 to 4 hours with basic hand tools, sockets, ratchet, jack stands. You'll get the step-by-step install video emailed after purchase and a 24/7 phone line if you get stuck. If you can change your own oil, you can run our protocol.
Real custom files. Built in-house by guys who've been turning wrenches and writing tunes on Cummins, Duramax, and Powerstroke platforms for years. Every tune is dialed to your year, your engine, and how you actually drive the truck. No outsourced generic tunes pulled off a shared drive.
Once we've got the base files for your platform, dialing it in for your specific truck takes about 20 minutes. Charging $300 for that didn't sit right with us. We'd rather give you the better experience and earn the call when your buddy's truck needs help.
You call us. Real diesel techs, US-based, picking up the phone. We help with install troubleshooting, tune adjustments, fitment issues, codes, anything. We don't disappear after the sale, and the line doesn't go to voicemail. Phone number is at the bottom of every email and on every page of this site.
Yes. The custom tune is reversible, flash the stock file back through your tuner and the truck reads as factory again. The only thing that's permanent is the deleted hardware itself, but most buyers in the diesel community see a properly executed delete as a value-add, not a deduction. We can also ship the OEM-style reverse plates if you want to put the factory exhaust back on for resale.
Lifetime warranty on the stainless delete pipe, no rust-through, no cracks, ever. 2-year warranty on the EGR delete plates, gaskets, and hardware. If anything fails, we ship a replacement same day. The tuner itself carries the manufacturer warranty through EZ Lynk or HP Tuners.
Orders ship from Fort Worth within 1 to 2 business days. Free express shipping anywhere in the lower 48. Most orders land in 3 to 5 days. You'll get tracking the second it leaves the shop.
