GReddy Supreme - SP

Also Compatible with 2017 Toyota 86 and 2017-20 Subaru BRZ!

The Supreme SP for the Scion FR-S & Subaru BRZ features a large horizontally mounted, 3-section muffler with a center inlet and an unique, tuned, internal "Y-pipe." This directs exhaust gases through a center chamber to reduce overall sound and improves flow to the outer straight-through sections. These outer sections of the muffler have our updated high-temp, internal sound suppression system. The exhaust is finished-off with dual GReddy slant-cut, double-walled tips in the factory bumper outlets. This cat-back exhaust also uses a simplified exhaust pipe routing with a large straight-through resonator in the mid-pipe, to tune-out any drone. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.

NOTE:  Becuse the Supreme SP for this model uses a factory type "donut gasket" flange to the factory piping, it fits both the 2012-16 FR-S / BRZ and the 2017-on "kouki" 86 / BRZ models (the slight change in the OEM factory over-pipe does not effect fitment on the Supreme SP).

GReddy Supreme SP – HG (High Grade) is our premium stainless-steel cat-back exhaust for the (FK8) Civic Type R. Besides the looks of the HG’s fully polished stainless-steel mandrel-bent piping and unique, functional GReddy three tip configuration; extensive research and development has lead to this supreme exhaust system.

The GReddy Honda Civic Type R exhaust keeps with the SP tradition of a street performance exhaust. Careful attention to both sound and performance was considered in the design of this system. The free flowing straight-though exhaust on the CTR’s turbocharged K20C1 engine netted just 88dba on our standardized revving sound test with an amazing 16whp increase on our chassis dyno. Large diameter, stainless-steel, 3” mandrel-bent piping is tucked up in the FK8 Civic Type R chassis to a larger specially shaped SP oval muffler, to maximize flow and control the sound quality. Exhaust flow exits through dual 2.5” ports on the muffler canister to carefully positioned, high polished exhaust pipes and dual-wall Tips. The Civic Type R’s rear diffuser exhaust opening is elegantly completed with a special GReddy Supreme SP badge, between the dual 4.5” SP tips. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.

The Supreme SP cat-back exhaust, for the turbocharged 10th generation Honda Civic Sport hatchback, improves the performance, sound quality and styling, by applying our signature SP (Street Performance) ideals into the design. The system not only incorporates large 76mm (3”) piping, but smoothes out and simplifies the heavier, factory, two muffler layout with a free flowing, compact single entry, dual outlet, oval SP muffler. This allows the turbocharged L15 engine to be more efficient for added performance, without having drone or being loud. The Supreme SP sound level was carefully tuned not to require any additional resonators; this also helps lighten up the system. The polished stainless-steel center-exit exhaust is finished off with stylish dual, double-wall, slant cut GReddy tips, to enhance the Civic’s sporty rear diffuser. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty

The unique dual muffler Supreme SP for the 10th generation Honda (FC3) Civic Si coupe features high-flow with a refined exhaust note. Under wide-open-throttle, spirited driving, the system offers the classic GReddy deep exhaust growl. To enhance the performance of the turbocharged 1.5L engine, this 3piece, cat-back exhaust connects to the factory piping (our system bolts to the factory exhaust system at the flange behind the engine/transmission) and expands to large 3” (76mm) forward-midpipe and mid-pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips. This tip and muffler combination is a great compliment to the Si’s sporty, but wide rear bumper tip opening. (We also offer a similar, application-specific system for the (FC1) Civic Si sedan.)  Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.

2017-on  Honda Civic Si 4door Sedan (only)

Designed specifically for the 10th generation (FC1) Sedan version of the Honda Civic Si, is our dual muffler Supreme SP cat-back exhaust. With similar features as our coupe version, the longer sedan version features high-flow with refined exhaust note. Under wide-open-throttle, spirited driving, the system offers the classic GReddy deep exhaust growl. To enhance the performance of the turbocharged 1.5L engine, this 3piece,  cat-back exhaust connects to the factory piping (our system bolts to the factory exhaust system at the flange behind the engine/transmission) and expands to large 3” (76mm) forward-midpipe and mid-pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips. The sedan version has a slight more aggressive tip angle and muffler combination is a better compliment to the Si sedan’s sporty, but wide rear bumper tip opening. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.
