Supersprint Metallic Cat System BMW 1-Series M Coupe 11-12

Supersprint Metallic Cat System BMW 1-Series M Coupe 11+

After the down pipes outlet flanges, the cross section shrinks down from 65mm to 60mm, (still larger than the factory 57mm tubing size) and it is maintained constant all the way to the tail tips. Once again there are no crushed sections in the tubing as with the factory system for clearance. In place of the factory quad cat design, Supersprint uses 2 high volume / high flow 100 cpsi metallic race cats. These are placed further away from the engine for the lowest restriction and the best results.

Please Note: Must be installed as a kit with P/N: 022 980 903 or 022 980 913.
