Fresh Produce Bottom Mount Manifold

Fresh Produce M54 Bottom-Mount Turbo Manifold
 
Built by Cory Misko of Fresh Produce, this traditional bottom-mount turbo manifold is designed for street-driven BMW E46 builds that also see frequent track use.
 
The compact bottom-mount layout allows the vehicle to retain air conditioning, making it an excellent option for powerful street cars that are still driven regularly during the summer. This manifold is currently used on our sponsored driver Dylan Lobbestael’s turbocharged M52 E46, proving that a serious turbo setup can still remain comfortable and streetable.
 
Each manifold is fabricated from Schedule 10 304 stainless steel, fully back-purged, and TIG welded for strength, durability, and consistent exhaust flow. The CNC-machined head flange is port-matched from the factory oval exhaust ports into the round stainless runners.
 
A dedicated motor-mount arm and bushing are included to provide the clearance required for the bottom-mount turbo configuration.

Wastegate Configuration
This manifold does not include a separate external wastegate flange. The wastegate must be integrated into the turbine housing. This configuration has been thoroughly tested and provides excellent boost control while keeping the manifold compact.
 
Lead Time
These manifolds are built to order. Please expect an estimated 4–6 week lead time unless otherwise noted.
