CTS Turbo Mercedes-Benz M177/W213 E63S High-Flow CATS are made to maximize exhaust flow for highest power gains.

Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST 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 4.0 Twin Turbo, our downpipe will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “punch!” as you bang through all the gears. The sound will be even louder if you already have an aftermarket exhaust system.

Product Details:

  • Cast T304 stainless steel, TIG welded back-purged construction
  • Replaces restrictive factory catalytic converter
  • Fits within OEM heat shields
  • Great power upgrade with uncompromising performance
  • Incredible sporty exhaust sound, subtle when cruising
  • No drone with factory exhaust


  • 2019-2020 Mercedes-Benz E63S AMG (W213)
  • 2019-2020 Mercedes-Benz AMG GT 63/63S (X290)

To remove the CEL that will occur, proper stage 2 tuning software must be used.
