My understanding is an X pipe for a turbo V8 help synchronize the sound waves from each exhaust bank a bit. The pipes are siamesed with an oval shaped cut where they connect. The point, well, not so much for power (strong debate that X or H pipes are of no benefit on a turbo V8) but instead for exhaust tone. Of course that is very subjective as some folk like deep and loud (they’ll be the ones using 3” straight pipes) while others like higher pitched, controlled sound. Listen to scott135i before and after sound clip. I hear a subtle, but noticeable change with the x pipe. I plan on having some mandrel formed pipes up to the M5 muffler. The big bonus for me then is the elimination of the bent and kinked mid pipes with the restrictive canister. I really like how scott’s 550i M5 mufflers with x pipe sounds so, at least for me, that’s my plan.
