Hi, I'm looking for an M5 exhaust that I can put on my e12. It's a modified 528i with a 3.3/3.5 litre engine bored to about 3.8. At one point it had an M5 exhaust on it but had to be taken off because of smog. i know how to beat the issue and I really need the system; headers, muffler, tips. Plez, if u have any information on how I can get an e12 M5 exhaust, plez e-mail me with it at Daredevil1005@hotmail.com Hopefully I'll hear from u soon, thx a lot, later.
