Tired of cracked y-boots? Here's a permanent solution to an old problem from APR: Bi-Pipe kits for Audi B5 S4 2.7T.

This cast aluminum y-pipe eliminates the original connecting hose, and bolts in place for added sealing strength. Its oversized recirculation valve ports limit boost spikes that commonly cause post-shift turbo lag.

Complete kit comes with mounting hardware and recirculation hoses. This exact-fit, bolt-on pipe assembly comes with pre-drilled mount that accepts your stock boost sensor.

Put an end to y-boot boost leaks with an APR Bi-Pipe.
