RPI was successful on giving our beloved Z4M some mad Hp/tq and now finally today Eloy called me and said their doing the R&D on the exhaust for the Z4M and will be doing a grp buy for us...and will be also tuned for the current software they have for our Z4M...all i ask right now is for us to be patient for those interested for the RPI exhaust as the R&D part will take a little time (good for us, so we can save $$$) but i'm sure our patience will pay off...
and yes the sound and exhaust tips will be bad@$$
pls put your name on the list for those interested...
