The legacy of the GReddy SP lives on with GReddy’s best version yet, the Supreme SP and to prove it carries a limited lifetime warranty! From the 1st flange to the new double-wall GReddy Tip, each Supreme SP system features a high-quality, hand Tig-weld 304 stainless-steel outer construction. Within the muffler, new straight-through and directed- straight-though chambered muffler designs allow GReddy to engineer a more refine exhaust note while increasing exhaust flow and performance. Classic GReddy street performance styling is maintained with excellent fitment and a stylish exhaust system layout. The Supreme SP not only designed to perform and sound great for each specific application; it matches the vehicle’s body-lines and styling.

This special Supreme SP exhaust for EK-chassis Honda Civic hatchback is part of the new modern GReddy take on classic tuned Honda(s). Designed specifically to enhance performance for larger displacement or turbocharged engine swaps, this version features large diameter 76mm (3”) piping, with only a short inlet portion of 63.5mm (2.5”) to allow it to still bolt up to factory style (K20) catalytic converter (downpipe) flanges. The four piece design features a large mid-pipe resonator and off-set oval Supreme SP muffler allow for deep rich exhaust note throughout the RPM range. Careful attention to routing allows for simple install, OEM like fitment and that iconic GReddy styling.
