The S54 T4 Tubular bottom-mount turbo manifold is a mid-mount design that places the turbocharger strategically in the E46 engine compartment. This is also an upgrade to your current Horsepower Freaks bottom-mount Turbo-kit. Limitations within the cast bottom-mount and plate manifolds, this tubular version will aid in spool and carry your turbochargers abilities throughout the entire RPM range.
**This manifold comes Open T4 flange using a single 44mm V-band wastegate outlet.**
