OEM Catalytic Converters
Selling a pair of OEM BMW E9X (E90/E92/E93) M3 catalytic converters. These were removed from the car to accommodate Active Autowerke stainless steel test pipes (also currently for sale). I reverted back to a stock midpipe/X-pipe for CA smog compliance. No O2 sensors included. Great for anyone using test pipes that wants to add a connector and swap back and forth from a catted to catless setup. Asking $450 OBO. |
