Our new 304 Stainless Steel downpipes will eliminate the most restrictive point in your W-body's exhaust system, including the dreaded "u-bend". The factory downpipe is even more restrictive than it looks since the bend is double-walled, which results in an actual diameter around 2". This 2.5" downpipe will signifcantly increase the potential flow for your exhaust, which allows your engine to breathe better and decreases knock.
Our downpipes feature interlocking flex section, lazer-cut flanges, 304 stainless steel tubing, and a Magnaflow stainless steel catalytic converter is optional.

Typical lead-time for most downpipes is about 1-4 weeks to ship out after the order is placed.
