The CTS Turbo High-Flow Cat for the BMW B58 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:
  • 4.5″ downpipe, reducing down to 3.15″ or 80mm for perfect fitment to a factory or aftermarket exhaust
  • High-flow 200cell catalytic converter
  • Precisely designed and tested on a real car in the real world
  • T304 stainless steel, TIG welded back-purged construction

We recommend replacing the downpipe gasket when installing, factory BMW gasket 18328612538 is required (not included). Catalytic converters damaged by "crackle tune" are not covered under warranty.
