The APR Cast Downpipe Exhaust System replaces the restrictive factory catalyst cross pipes and resonators with an upgraded 76mm stainless steel mandrel-bent system, featuring port-matched cast inlets, high-flow catalysts and various other features. Expect better throttle response, more horsepower and an intoxicating exhaust note, while remaining civilized during normal daily driving. It’s the best performance upgrade for the 4.0 TFSI following the APR ECU Upgrade and it’s all designed and assembled in-house, using premium materials and world-class manufacturing techniques few can match.

  • Full 76mm downpipe system
    The APR system is a full downpipe upgrade as it replaces the kinked 60mm catalyst cross pipes and resonated midpipes with straight through, 76mm mandrel-bent tubing.
  • Port-matched investment-cast downpipe inlets
    The factory inlets are restrictive. APR’s cast system allows for massive, port-matched inlets that smoothly neck down over a long distance. The result is improved flow, better response and more power.
  • Dual, high-flow catalysts
    GESI’s encapsulated catalysts are known for their strength and performance. Expect lower emissions, reduced noise and less exhaust smell compared to catless setups, all without negatively impacting performance to over 1,000 HP. Furthermore, with the catalyst moved, expect a cooler engine bay!
  • T304L stainless steel construction
    Premium grade T304L stainless steel resists corrosion and stands the test of time.
  • OEM-style low-profile slip-on clamps The APR slip-clamps are easy to use, resist leaks and pipe deformation better than swedged setup, are lower profile than vbands and flanges and don’t require replacement gaskets.
  • OEM-style internally-corrugated flex sections APR’s flex sections are internally corrugated to increase flow and prevent failures common with braided flex sections.
  • Compatible with the OEM catback exhaust
    Bolt-on and go! The system is fully compatible with the factory catback exhaust.
  • All hardware and instructions included
    New OEM gaskets, oxygen sensor harnesses, clamps, brackets and install instructions are included to make the install as headache free as possible.
  • Limited lifetime warranty
    The best system on the market also carry the best warranty in the industry! 7878
  • APR Stage II ECU Upgrade price waived
    With every APR downpipe purchase comes a free upgrade to Stage II from Stage I, saving consumers hundreds of dollars!
