PROFILE

Complete your S55 upgraded charge piping with the ARM S55 J Pipe!  This J Pipe is the final piece of piping on the S55 before the charge air enters the intake manifold.  BMW constructed the OEM J Pipe of plastic which is prone to cracking an detaching from the throttle body under boost.  The ARM S55 J Pipe is constructed of T6061 aluminum for a durable replacement that will hold up to even the most demanding builds.  

S55 J Pipe

The ARM S55 J Pipe is designed to lock onto the stock throttle body using a CNC machined connector.  This connector incorporates a locking C-clip design which replaces BMW's one-time use plastic strip to create a secure connection to the throttle body.

Included with the ARM S55 J Pipe are two pre-plugged 1/8 NPT fittings which allows for post-intercooler methanol or nitrous injection.  This is the preferred location of injection for many S55 tuners.  J-Pipes with only one methanol port are not able to supply a sufficient amount of methanol for advancing the timing enough to make any substantial power increases.  

S55 J PIPE

For reinstalling your S55 vacuum line, the ARM J Pipe has a precisely machined vacuum line connection port to prevent any leaks, a common issue on many other S55 J Pipes.

The precision-engineered tubular design is optimized for maximum exhaust flow, reducing backpressure and enhancing turbo efficiency. This manifold is similar to ones being sold on AliExpress and other overseas markets. However, we've partnered directly with the manufacturer to provide these manifolds in the highest of quality. Unlike those that are drop-shipping similar manifolds from unreliable sources. You are purchasing directly from the source.
