The CTS Turbo high-flow cat for BMW N55 (Pneumatic Wastegate) is made to maximize exhaust flow for the highest power gains. Do not compromise performance and sound with factory parts – unleash your BMW’s potential!

Designed using the latest in CAD technology; this part is made to fit perfectly in place of your factory downpipe. Manufactured from T304 stainless steel, hand TIG welded and back purged to ensure years of reliable performance.

Product Details:

  • Precisely designed and tested on a real car in the real world
  • T304 stainless steel, TIG welded back-purged construction
  • Replaces restrictive factory downpipe
