* Required Fields



After months of testing and engineering to ensure the perfect fit and performance, we are happy to announce our B5 S4 3.5" exhaust system.  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
  • Hand fabricated at 034Motorsport
  • 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
  • Available with midpipes to accomodate virtually any exhaust configuration, choose below.
  • Single 3.5" exhaust tip.
  • Single muffler.

Midpipes are required for bolt-on installation, and available with or without high-flow catalytic converters.

  • For"Dual 3" Downpipes" - Designed for those using our 034Motorsport 3.5" Exhaust System with 034Motorsport 3" Downpipes. This midpipe allows 034 downpipes to mate directly to the 3.5" exhaust for maximum flow, out of the turbo into 3" downpipe, into dual 3" midpipe transitioning into 3.5" exhaust.  This means if you've purchased our downpipes in the past, you would not use the midpipes you arleady have, but would purchase this new dual 3" to 3.5" midpipe.  The advantage to this configuration is that there is no necking down to 55mm to accomodate stock connections, full 3" to 3.5" flow is maintainied. Note, 3" High Flow Cats can be added to this version of the midpipe.

Please Note: We include a bracket that relocates the middle exhaust hanger (by the rear diff), please be sure to use this bracket to relocate this hanger, otherwise major fitment issues will occur.

I have the full 3.5" exhaust with dual mufflers and cats on on my DD K04 setup. Fit and finish is excellent. Sounds awesome and no droning. It helps to use 5/16" locking collars on the hangers to keep the exhaust centered. You lose some ground clearance in the back with the 3.5 piping and a little more with the mufflers but the clearance is still fine to deal with speed bumps, etc.
