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

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

Fair Quality, Hour and a half build
Color: Black, Size: 132in-Large Metal Base
Key things: It does (more or less, not completely) fold in on itself, it does block nearly all visibility (especially from an angle), it was only about an hour and thirty minutes to put together, and it is light weight. Do I recommend? Yeah.

Assembly was a bit rough
Color: Black, Size: 132in-Large Metal Base
It is serving the purpose it is bought for. However the assembly was harder than it should have been. Joining the parts A and B (two iron pipes) was very hard. We can't use any tools to do that and it has to be done manually and every joint was very tight and very hard to to do. I had to struggle to make 24 joints for the length I need. At one point I was going to return it, but I needed it very badly so continued with the assembly.
