MBRP GMCA425 3 Inch Turbo Downpipe
For 2001, 2002, 2003, 2004 GM 6.6 Duramax LB7
The MBRP Turbo Downpipe eliminates the restrictive factory downpipe. Featuring a mandrel bent aluminized steel construction, the MBRP 3" Turbo Downpipe provides a smoother flow from the turbo resulting in lower EGT's and increased performance, throatier sound, and faster turbo spool-up.
- Each Downpipe is coated with a satin black high-heat coating and wrapped with a high-heat thermal wrap for added protection. A durable 1/2" thick flange is used to eliminate warping and sealing issues. This Downpipe is a direct bolt-on replacement and is manufactured with precision bends for the perfect fit that you've come to expect from MBRP.
