I have a 2009 E92 M3 and am interested in trading my Macht Schnell Test pipes bolted to my stock x-pipes (along with my stock cats) for a stock x-pipe with cats. Essentially I am looking to put my car back to stock and would rather like to bolt a stock x-pipe back than uninstall my test pipes and weld the cats back in. The test pipes have less than 5k miles on them and my car has less than 30k miles in general. I am in Stuttgart, but can do the swap somewhere in the surrounding area.
