The Racing Beat MX-5 Race Connecting Pipe (2-piece) is intended to replace the stock mid-pipe on the MX-5, thereby eliminating the integrated secondary catalytic converter and presilencer unit. For dyno result information for the Racing Beat MX-5 Header and Race Connecting Pipe unit, visit this link (PDF).
Manufactured using 16-gauge, 2.375-inch OD stainless steel tubing, this connecting pipe features mandrel bends and OEM style connecting flanges. Designed as a bolt-on component, this connecting pipe is easy to install and utilizes all existing mounting brackets and hangers. Although the photos show this pipe as a one-piece unit, we are now producing this race pipe as a TW0-PIECE version to faciliate shipping. Website photos will be changed at a later date.
Fitting Note: This connecting pipe section will mate to the outlet of the stock exhaust manifold or Racing Beat Header, and the inlet of the stock muffler or the Racing Beat Muffler. On international models (UK-RHD) this connecting pipe MUST be installed with a Racing Beat Header for correct fitment - this connecting pipe will not mate to the outlet of the stock exhaust manifold section due to length differences.
Emissions Note: The stock mid-pipe does not feature an oxygen sensor after the catalytic converter. (The oxygen sensors in the MX-5 exhaust system are located before and after the primary catalytic converter, which is located under the stock exhaust manifold near the engine.) Therefore, installation of this race connecting pipe will not impact the OBD II system and installation of this race pipe will not cause a "check engine" light to occur. However, since a factory-placed catalytic converter is being removed by the install of this component, this race pipe is NOT considered emissions legal for street use.
