| Maximize performance with Supersprint's Connecting Pipes!!! |
These are alternative pipes for the metallic race cats above. After the turbo down pipe outlet flanges, the cross section shrinks down from 65mm to 60mm, (still larger than the factory 57mm tubing size) and it is maintained constant all the way to the tail tips. Once again there are no crushed sections in the tubing as with the factory system for clearance. In place of the factory quad cat design Supersprint has designed 2 straight pipes for race track or export purposes only. Give your 135i the best with the Supersprint Connecting Pipes.
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: Part #022 980 913 Must be used with 022 980 902 Cats or 022 980 912 Cat Replacement Pipes.
