The MBRP Aluminized Steel Down Pipes are designed for those looking for great quality at a reasonable price for their Chevy/GMC 6.6L Duramax. If you demand top performance on a little tighter budget, look no further.
Replace that restrictive factory downpipe with a MBRP direct replacement downpipe for more flow, fuel economy, and better performance. Removal of OEM catalytic converters may be a violation of emissions laws in your jurisdiction.
