NEW! SSAutochrome Twin-1 Catback Exhaust System

1999-2002 Audi S4 B5 2.7L Bi-Turbo Quattro

 PRODUCT OVERVIEW

Introducing the latest generation SSAutochrome Twin-1 Catback Exhaust System for the legendary Audi S4 B5 2.7L Bi-Turbo. Designed for enthusiasts who demand outstanding build quality, increased exhaust flow, and an aggressive European performance tone, this system combines premium T304 stainless steel construction with precision mandrel bends for maximum performance.

Unlike restrictive factory exhaust systems, the Twin-1 design utilizes smooth-flowing 2.5" (63mm) mandrel bent tubing feeding into a high-flow single polished muffler and finished with beautiful dual 3" rolled-edge polished exhaust tips. The result is improved exhaust scavenging, quicker turbo response, reduced backpressure, and an unmistakable exhaust note.
