S-Pipe for Z4M
Other than supersprint, does anyone make an s-pipe for the z4m?
I have supersprint x-pipe and powerloop mufflers installed already.
I have on order the fabspeed headers and evolve-r tune.
My shop is telling me they can fab them for about $400, but I would rather buy a set that are ready to go.
The supersprint are too expensive and no one keeps them in stock.
Another option, is that I can have the shop gut the existing s-pipe cats and go that route.
Any suggestions?
