MBRP ARMOR PLUS Series 4in Downpipe-Back Exhaust Single Side Exit for 2001-2004 Chevrolet/GMC Silverado/Sierra 2500/3500 (6.6L)

Fits 2001-2004 Chevrolet Silverado 2500 HD/3500 and GMC Sierra 2500 HD/3500 (6.6L).

The MBRP ARMOR PLUS Series downpipe-back exhaust system is designed for truck owners seeking a balance of long-term durability and value. Constructed from 4-inch T409 stainless steel, this system provides superior protection against penetrating rust compared to aluminized steel. Every pipe is mandrel-bent to maintain a constant diameter throughout, eliminating restrictive rippling in the bends to maximize exhaust flow, lower EGTs, and improve overall engine efficiency.

Built for a straightforward installation, this system utilizes a single side exit and is designed as a direct bolt-on replacement. The ARMOR PLUS series is specifically engineered to handle standard road conditions and moderate precipitation, delivering the signature MBRP performance sound and improved exhaust scavenging for your 6.6L diesel powerhouse.
