DESCRIPTION
Product Overview
-
While upgrading to a 4" exhaust system significantly drops EGTs and increases flow, the standard 4" tailpipe can still look small and unfinished under large, lifted heavy-duty trucks.
- This 4-to-6 inch polished exhaust tip provides the ultimate finishing touch. Acting like a massive natural megaphone, it amplifies your diesel’s exhaust notes into a much deeper, authoritative rumble while giving your truck a aggressive, heavy-duty rear profile.
Key Features
- Premium Polished Stainless Steel: Crafted from high-grade stainless steel to resist rust, flaking, and discoloration caused by corrosive exhaust gases and harsh winter road salt.
- Aggressive 6" Megaphone Blast: Converts your 4" tailpipe into a massive 6" flared opening, naturally deepening your exhaust note for a throatier, deeper tone.
- Sleek Slant-Cut &Rolled Edge: Features an angled slant-cut profile to seamlessly align with your truck's quarter panel and a thick rolled edge for a muscular, premium look.
- Integrated Drainage Hole: Engineered with a discreet bottom weep hole to quickly drain trapped water, preventing internal moisture buildup and rust.
FAQ
Q: How will expanding from 4" to 6" affect my exhaust note?
A: It acts like a megaphone. It naturally deepens the sound, transforming high-pitched rasp into a much lower, throatier rumble without drastically increasing raw volume.
Q: Will the massive 6-inch outlet clear my rear bumper or quarter panel?
A: Usually yes, but you should check clearance. Because a 6" tip is significantly wider than a standard 4" pipe, ensure you have at least 1 to 2 inches of clearance around your current tailpipe so the new flared tip doesn't vibrate against your bumper or body paint.
Q: How easily does this polished finish show diesel soot or black smoke?
A: The mirror-polished finish will show black carbon and diesel soot quickly if your truck is tuned or lacks a DPF. If you don't want to wipe down the polished stainless steel after every drive, we highly recommend choosing our High-Temp Black Coated version instead.
Q: Will jumping from a 4" pipe to a 6" tip affect my engine's backpressure or turbo spool?
A: No. The tip is located at the very end of your exhaust system, way past the turbo and downpipe. Expanding the very tip of the tailpipe only alters the acoustics (sound depth) and aesthetics;it has zero impact on engine backpressure, torque, or turbo performance.

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.

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.
