BMW 135i SuperSprint Connecting Pipe

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. Note: Must be used with 022 980 902 Cats or 022 980 912 Cat Replacement Pipes.
