Supersprint X-Pipe for 2006-08 BMW Z4 M Coupe/Roadster [E85]

All Supersprint alternate connecting pipes are mandrel bent for maximum performance. The alternate pipe is designed to replace a resonator that is standard in that same position. This option will increase sound slightly and reduce overall system cost. The polished pipes are manufactured from 100% 304 stainless steel, while the black pipes are aluminized mild steel.
