True catback exhaust for 2003 z4 2.5i?

Anyone know of any? I don't want just a muffler.

Thanks

supersprint offers a solution. its very very expensive when its all said and done and you really aren't gonna get much of a HP gain. only other option would be if the BMS system that is now out there for z4m's will be modified to fit our cars.

*fingers crossed*

thanks. I have already checked the Supersprint system, but I had problems with SS on my E46 M3. The welds broke on the end of my headers where it bolts to the first resonator, so I won't buy supersprint again.

I believe Racing Dynamics has a cat back, also i think Eisenmann has a muffler and a center connector pipe option as well.
