Only one of these available at this price! This set of high-performance metallic catalyzers installs in place of your 335i main catalysts, the highest source of exhaust restriction, period. The factory catalysts substantially hinder exhaust flow, which on a twin turbo engine like the 335i, makes for a substantial power loss. Instead of the factory 335i quad cat design, Supersprint uses 2 high volume / high flow 100 cpsi metallic race cats for lowest restriction. 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. There are no crushed sections in the tubing as with the factory system, further contributing to better exhaust flow. Fits all E90 335i sedan, E92 335i coupe & E93 335i convertible, 2007, 2008, 2009, 2010.
