DESCRIPTION
Product Overview
- Over time, the factory up-pipes on 01-16 Duramax trucks suffer from a guaranteed failure point—the fragile OEM bellows, Under intense exhaust heat and high drive pressure, these thin factory bellows warp, crack, and leak.
- This leads to severe turbo lag, lost boost pressure, skyrocketing EGTs, and annoying exhaust leaks inside the engine bay.
- this complete kit permanently eliminates the factory leak point, restores lost boost, and drops EGTs whether you are towing heavy or racing on the track.
Key Features
- Mandrel-Bent Tubing: Smooth, unrestrictive bends maximize exhaust gas velocity heading into the exhaust housing of the turbocharger.
- Reinforced Interlocking Bellows: Designed with heavy-duty internal sleeves that protect the flex section from extreme exhaust velocity, preventing cracking and leaks permanently.
- Restores Lost Boost: Seals the exhaust system completely, ensuring maximum drive pressure reaches the turbo to eliminate lagging and restore crisp throttle response.
- Purposely Indented Pass-Side: The passenger-side pipe is custom-profiled with a precision indentation to ensure perfect clearance against the tight firewall.
FAQ
Q: Is this just the passenger side? Do I also need the driver side?
A: This is the passenger side up-pipe only. The passenger side is the long pipe that wraps behind the engine. The driver side is a short, straight pipe from the driver manifold to the turbo. The driver side rarely fails — the bellows and complex bends on the passenger side make it the one that cracks.
Q: Does this pipe affect emissions or the check engine light?
A: No. The up-pipe is a purely mechanical component upstream of the turbo. It does not contain sensors, EGR connections, or emissions-related hardware. A leak-free up-pipe simply restores the exhaust path to the turbo.
Q: Will this pipe work with a DPF delete or full exhaust system?
A: Yes. The up-pipe is before the turbo — it has no connection to the DPF/delete system at all. A delete exhaust or aftermarket downpipe downstream has no effect on the up-pipe fitment.
Q: I hear a whistle from my engine but my downpipe and delete pipe look fine — should I check the up-pipe?
A: Yes. A pre-turbo exhaust leak (cracked up-pipe bellows or leaking manifold gasket) creates a distinct whistle that sounds different from a turbo spool. If you’ve already checked the post-turbo side (downpipe, delete pipe, gaskets) and found no leaks, inspect the up-pipe bellows next.
