GReddy Supreme - SP

Compatible with 2017 Toyota 86 and 2017 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.

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. Careful attention was placed on the Civic Type-R’s exhaust sound characteristics, when incorporating our purposeful, high-flow, tri-routing layout. The large 76mm (3”) diameter piping flows smoothly through a large mid-pipe resonator and then branches out to the high-flow 3” center SP muffler and the two side-mounted sound chambers, before exiting the GReddy triple exhaust tips. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.

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.

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.

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.

The Supreme SP for ’09-’14 Acura TSX offers a refine exhaust note with elegant styling to match. The classic dual oval muffler system with large free flowing 63.5mm (2.5”) piping produces no exhaust drone.

The muffler and tip best match the TSX’s aero styling. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty

The Supreme SP for the Subaru STI Sedan features much larger diameter piping, resonators and mufflers, but also smoothes the layout for maximum performance with good sound suppression. This cat-back exhaust starts out with a full 3” mid-pipe with a large straight-through resonator to tune out drone. The next section smoothly transitions into dual 2.5” diameter piping. Improved dual GReddy straight-through mufflers with dual, double wall tips on each muffler finish off the exhaust. GReddy designers carefully position the dual mufflers and staged tips to flow with the GV-chassis’ bodylines.

The Supreme SP for the Subaru STI hatchback features a large horizontally mounted, 3-section muffler with a "tucked-away" layout. This routing allows for the large 3” diameter piping to more smoothly enter the muffler’s center section. Exhaust gases exit each side of the revised muffler via the two 2.5” diameter piping to quad staggered 3.5” GReddy double-wall slash cut tips, The non-tapered 3” mid-pipe also encases a large resonator section to tune-out drone. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
