QKspl Bellmouth Downpipe for Mitsubishi Evo X by CP-E

The factory O2 housing bolted to the turbo on the Mitsubishi Evolution X is very restrictive. And it limits the amount of exhaust that can flow through the area. We wanted to minimize restrictions and open up the flow with a high volume bellmouth. We also wanted to create a smooth transition to the 3 piping that mates up to the test pipes and cat back exhausts.

Taking advantage of casting parts from 304 stainless steel the cp-eâ„¢ EvoX bellmouth has smooth transitions and contours that ensure smooth flow. A flex section is incorporated into the design to allow for movement of the motor. The 304 SS laser cut flange is hand TIGwelded for strength.


  • Full Stainless construction using the best USA steel
  • CAD designed 304 SS Cast Bellmouth
  • 3 piping and 304 stainless flange
  • MIG and TIG welded for strength and precision assembly
  • Additional O2 bung and cap for wideband
  • EGT bung and cap
  • Complete Bolt-on part, flawless integration with stock system
  • Made in the U.S.A.

Please Note: While this may not trip a Check Engine Light, we cannot guarantee that all of the codes will be in the “ready” state.
