Masata 3 inch Race J Pipe for BMW N54 and N55 engines - E82 E88 135i, E90 E91 E92 E93 335i 335xi - Part Number MST0251

Unlock stronger boost, smoother throttle response and dependable reliability with this high-flow 3 inch Masata J Pipe. Built for E-chassis 1 Series 135i and 3 Series 335i including xDrive variants running the N54 or N55 engine, it replaces restrictive lower pipework with a robust, leak-resistant alloy boost tube designed to handle higher boost and heat cycles.

Pair it with the Masata 7.5 inch Race Intercooler to create a full 3 inch charge-air path from cooler to throttle for maximum airflow and reduced pressure drop. The kit includes the additional hardware and hoses required for a secure, hassle-free fit.

Why this Masata J Pipe is a winner
