Product Info


After months of testing and engineering to ensure the perfect fit and performance, we are happy to announce our catback exhaust system for the B5 S4 featuring a full 3.5" rear section. This exhaust utilizes our popular 3.5" exhaust system with a stock-fit midpipe to mate up with factory downpipes. A complete solution for those looking to keep the OE catalytic converters and downpipes, with all the sound of a free flowing 3.5" axle-back exhaust. Fully mandrel bent and made from stainless steel, these systems offer the following features:

  • Fully mandrel bent tubing for full cross sectional flow
  • 304 series stainless steel
  • CNC machined V-band flanges for connections, also band clamp connections for flexible installation and adjustability
  • Minimal drone on light load and cruising, the sound of a "raped ape" on wide open throttle
  • Single 3.5" exhaust tip
  • Single muffler

  • 034Motorsport 3.5" Rear Exhaust System
  • 034Motorsport Stock-Fit Midpipe
  • 3.5" V-Band Clamp
