A flagship exhaust fitment from one of the most respected names in the Honda performance tuning community. Ships fast across Canada and the US.\u003c\/p\u003e\n\n\u003ch3\u003eGReddy Supreme SP — Sound, Quality, and Character\u003c\/h3\u003e\n\u003cp\u003eThe Supreme SP is GReddy’s premium cat-back exhaust line, engineered to deliver a genuine sport exhaust character without the cabin drone and harshness of straight-pipe or race-spec systems. GReddy’s SP (Special Performance) tuning targets an exhaust note that is assertive under acceleration and at high RPM — where the FK8’s K20C1 builds its power — while remaining composed at idle and highway cruise speeds. 304 stainless steel tubing and polished tip finish are standard throughout the Supreme SP line. For the FK8 Type R community, the GReddy Supreme SP is one of the benchmark cat-back choices — a proven fitment on a car where the OEM exhaust is already well-regarded, and where the aftermarket upgrade needs to deliver genuine improvement in character and sound quality to justify the investment.\u003c\/p\u003e\n\n\u003ch3\u003eFK8 Type R — Why Upgrade the OEM Exhaust\u003c\/h3\u003e\n\u003cp\u003eThe FK8 Civic Type R ships from the factory with a well-engineered triple-exit exhaust system that already produces a sport character relative to standard Civics. The case for upgrading to the GReddy Supreme SP is sound quality refinement, a more prominent exhaust note across the RPM range (particularly in the mid-to-upper band where the K20C1 is most alive under boost), and the aesthetic upgrade of a premium aftermarket tip finish. The Supreme SP is not primarily a power-seeking modification on a stock FK8 — it is a character and quality upgrade. For buyers primarily seeking power gains, a downpipe upgrade is a higher-priority modification on the FK8 platform.\u003c\/p\u003e\n\n\u003ch3\u003e304 Stainless Steel Construction\u003c\/h3\u003e\n\u003cp\u003eThe Supreme SP is built from 304-grade stainless steel — the standard for premium aftermarket exhaust systems. 304 stainless provides excellent corrosion resistance in road salt, moisture, and heat-cycling environments, and maintains structural integrity and finish quality significantly longer than aluminized steel alternatives. For a flagship exhaust at this price point on a halo performance car, stainless construction is the appropriate specification.\u003c\/p\u003e\n\n\u003ch3\u003eFK8 vs FL5 — Generation Confirmation\u003c\/h3\u003e\n\u003cp\u003eThe FK8 Civic Type R was sold in North America from 2017 through 2021. The 2022+ Civic Type R is the FL5 generation — a different chassis, different exhaust routing, and different fitment specification. This GReddy 10158214 exhaust is for the FK8 only. If you own a 2022 or newer Type R, this system will not fit. Confirm your Type R generation (FK8 or FL5) before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eFK8 only — 2017–2021 Honda Civic Type R. Not compatible with FL5 (2022+).
