Megan Racing Test Pipe, Civic Si/RSX/RSX-S

The K20A2 Motor in the Acura RSX Type-S is a motor that simply screams for performance in the high-end. And although the exhaust system is suitable for the average street user, the performance enthusiast will always seek the highest potential from this machine.

Megan Racing now offers the High-Flow Test-Pipe with the free flowing resonator for the Acura RSX Type-S. It's well known that the exhaust system on most cars is one of the most restrictive and power robbing variables on any vehicle with the Catalytic Converter being a prime factor for that restriction. The Megan Racing Downpipe eliminates the OEM Restrictive Catalytic converter and replaces with a high-flow system that features a larger exhaust tube that finishes with an impressive 2.3" outlet to connect to your Cat-Back Exhaust System.

A complete Bolt-On part with no modifications necessary to your vehicle. Featuring T-304 Stainless Steel that will resist corrosion; and is polished to a mirror-like finish for that perfect Show-Car touch. Fabricated with two (2) O2 Sensor bungs to conform to the OEM fitment and OBD-II standards.

Note: Although O2 Sensor bungs are provided, an O2 Simulator may be required to prevent any Check-Engine lights.

Pipe size for the RSX-S model is 2.5" and the pipe size for the RSX base model and Civic Si model is 2.25".

Update: The RSX Type S version of this test pipe is a straight through pipe, Megan Racing no longer offers the resonated version. The RSX base model and '02-'05 Honda Civic Si version is still a resonated pipe as pictured.
