Upgrade the restrictive factory downpipe on your 2015.5–2016 6.6L Duramax LML with the PPE 3" Stainless Steel Downpipe. The OEM pipe features a crushed oval design that limits exhaust flow, while this mandrel-bent 3" round pipe improves airflow, durability, and overall performance.
Constructed from high-quality 304 stainless steel and paired with a woven titanium heat sleeve, this downpipe is built to withstand extreme conditions while helping reduce engine bay temperatures.
Key Benefits:
- Eliminates restrictive factory downpipe design
- Improves exhaust flow and performance
- Reduces under-hood temperatures
- Long-lasting corrosion-resistant construction
Features:
- 3" mandrel-bent tubing for smooth exhaust flow
- 304 stainless steel construction
- Integrated M20-1.5 and M14-1.5 sensor ports
- Woven titanium sleeve for heat management
- CARB EO# D-701-30 compliant
Fitment Notes:
- Fits 2015.5–2016 models with 3-bolt triangular flange
- Early 2015 models with V-band clamp require a different downpipe
