do88 Cast Aluminum Charge Pipe - BMW S58 (G80/G82/G87) 2020-2026

The S58 leaves the factory with a Y-shaped plastic charge pipe joining both turbochargers to the throttle body, and it becomes a failure point once boost and charge temperatures rise on a tuned car. do88 replaces it with a cast aluminum Y-pipe plus a mandrel-bent pipe from the rear turbocharger, CNC-machined turbo and throttle body adapters, and a larger throttle body quick disconnect matched to the throttle bore. do88 measures 960 CFM at 150 mbar (2.17 psi) against 835 CFM for the OEM pipe, roughly 15 percent less restriction. Two 1/8 NPT ports are machined into the pipe for water/methanol injection or a boost pressure sensor, with plugs supplied for unused ports.
