DieselR 2007-2010 Duramax Turbo-Back Exhaust System LMM 2500/3500

The factory exhaust system on your 2007.5–2010 LMM Duramax is robbing your truck of airflow and holding back serious power. The DIESELR LMM Duramax Downpipe-Back Exhaust replaces restrictive stock piping with a mandrel-bent, heavy-duty system designed for lower EGTs, increased power, and an aggressive tone that says you mean business.

 Built to Perform. Built to Last.

• Corrosion-resistant and ready for harsh conditions
• Mandrel-Bent Tubing: No crimps or bottlenecks
• Leak-Free Fitment: Includes clamps and upgraded flanges
• Pre-Welded Hangers: For secure, hassle-free install

This is a downpipe-back exhaust that’s built for the long haul — no weak welds, no compromises.
