CTS Turbo HIGH-FLOW cat set for Mercedes Benz C43 C400 C450 E43 E400 E450 with M276 engine is 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 3.0 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
  • 200cpi catalytic converters
  • Fits within OEM heat shields
  • Great power upgrade with uncompromising performance
