Aluminized 3-Inch Turbo Down Pipe — Designed for 2001–2004 GM Duramax LB7

Description

Remove the restrictive OEM downpipe and replace it with MBRP’s GM8425 3″ Downpipe. This will help your LB7 breath by increasing the exhaust flow of your turbocharger. Featuring full 16 gauge mandrel bent tubing to maximize flow, as well as an extremely durable high-temperature ceramic coating, these pipes will deepen the sound of your Duramax while lowering EGT’s and provide a quicker throttle response. The install process is as simple as it gets from the precision bending that you’d expect from an MBRP kit.
