The ETS Evolution X High Flow Cat Test Pipe is a direct replacement of the factory catalytic pipe.  This has been dyno tested for a 10-15whp increase over the factory catalytic pipe.  Works with factory downpipe and factory exhaust system as well as any other aftermarket exhaust system that mounts in the factory location.


  • Direct Replacement J-Pipe O2 Bung (Prevents Check Engine Lights)
  • Wideband Bung w/ Plug included
  • Stainless Steel
  • Factory bend to clear the driveshaft unlike the competitors who use a straight pipe that will rub against the driveshaft.

- 100% Stainless Steel construction
- Metal Monolith is much more resistant to the effects of vibration than traditional ceramic bricks and capable of withstanding higher operating temperatures.
- 200 cell per Sq. Inch catalyst flows at 578 CFM, up to 40% better than a typical ceramic core converter.

  • Hi, Are you able to provide an estimate on how loud this is compared to the factory CAT?. As in New Zealand we have strict noise rules.

    I do not have any exact data comparing them, but it is quite a bit louder.

  • Hi there. Do you think I will require an adapter flange if running this cat with the stock downpipe and an aftermarket magnaflow exhaust? Also how long are your XL tshirts & hoodies I am 6'2? Thanks, Dan 2008 Evo MR.

    If you are running a factory part connected to one of our exhaust parts we recommend the adapter flange to increase the sealing surface. This keeps the gasket from blowing out. 

    I would say they are average/normal length compared to most T-Shirts.

  • Does this Test Pipe work on a Mitsubishi Ralliart?

    Yes, this works on the Evo X and the Ralliart.
