S55 M3/M4/M2C NORCAL DYNAMICS TITANIUM J PIPE F80/F82/F83/F87

Introducing the Norcal Dynamics Titanium J-Pipe
For BMW F80, F82, F83 M3/M4 and F87 M2 Competition (S55)

The factory plastic J-pipe is known to fail—even at stock boost levels. Upgrade your S55 platform with Norcal Dynamics’ fully titanium J-pipe, engineered for strength, performance, and peace of mind under any boost conditions.

Our J-pipe delivers increased airflow to the throttle body with a precision-crafted, fully welded titanium construction—lightweight, durable, and built to perform. Two integrated methanol bungs make it ideal for those running water-meth setups.

With a consistent 3" inner diameter, it's the largest throttle body J-pipe available for this platform—resulting in quicker throttle response and reduced turbo lag.

Key Features:

• Full titanium construction — ultra-lightweight, strong, and corrosion-resistant

• Consistent 3" inner diameter for maximum airflow

• OE-style fitment for seamless installation

• Two integrated methanol injection ports

• Enhanced throttle response & reduced turbo lag

• No tuning required
