CTS Turbo B9 S4/S5 3.0T (EA839) high flow cat is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts – unleash your B9 S4/S5 3.0T potential!

Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance.

In addition to unleashing the power and performance of your 3.0T, the CTS B9 S4/S5 3.0T EA839 high flow cat will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “braappp!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.

Product Details:

  • Designed and tested on a real car in the real world
  • T304 stainless steel, TIG welded back-purged construction
  • Replaces restrictive factory catalytic converter
  • Install hardware included
  • Great power upgrade with uncompromising performance
  • Incredible sporty exhaust sound, subtle when cruising
  • No drone with factory exhaust
  • Stunning polished finish for great looks

Fitment:

  • 2018+ Audi S4 3.oT (EA839)
  • 2018+ Audi S5 3.oT (EA839)

To remove the CEL that will occur, proper tuning software must be used.
