SKU: S60210P / UPC: 882963131850

MBRP 5-Inch Downpipe-Back Exhaust System for 2001-2004 Chevrolet Silverado and GMC Sierra 2500HD/3500HD 6.6L Duramax Diesel

The MBRP 5-inch downpipe-back single side exit exhaust system. This Armor Lite series setup delivers noticeable gains in horsepower and torque through its mandrel-bent design that reduces backpressure for smoother exhaust flow, quicker throttle response, and better fuel efficiency compared to stock systems or smaller-diameter aftermarket options. The deeper, more aggressive exhaust note turns heads on the road or trail, providing the raw power and presence your heavy-duty truck deserves without the complexity of multi-stage kits. Built for daily drivers and hard-working rigs, it installs bolt-on style in a few hours, reusing factory components where possible for a direct fit that outperforms restrictive factory piping and entry-level competitors in durability and sound quality.

Precise Vehicle Fitment

This exhaust system fits the following configurations exactly:

• Years: 2001-2004
• Makes: Chevrolet Silverado, GMC Sierra
• Models: 2500HD, 3500HD
• Engine: 6.6L Duramax V8 Diesel
• Cab Styles: Extended Cab or Crew Cab only
• Exclusions: Does not fit vehicles with catalytic converters; excludes 2002-2004 California emissions models

Note: Installation may require minor cutting of pipes based on bed length 9.5 inches off the mid-pipe for extended cab models, and 13 inches off the over-axle pipe for short-bed crew or extended cab trucks. Long-bed versions need no cuts. Always verify your truck's setup against these specs for seamless integration.

Why This Exhaust System Stands Out for Your Duramax

The MBRP S60210P pulls ahead with its precision-engineered bends that hug the frame for ground clearance and heat shielding, avoiding the rattles or leaks common in cheaper universal kits. You'll feel the difference in acceleration and towing pull right away, with exhaust gases exiting faster to support your 6.6L's full potential.

Backed by a 1-year warranty against defects, it's engineered in Canada for North American trucks like yours delivering reliable results mile after mile. Pair it with stock or upgraded tuning for even more gains.
