Key attributes of the Supreme SP on the DC2\/DB8 Integra platform:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eT304 stainless steel:\u003c\/strong\u003e Full T304 stainless construction from the mid-pipe flange to the tip. T304 stainless provides corrosion resistance for year-round use, including road salt environments. The Supreme SP will outlast mild steel aftermarket systems significantly in Canadian driving conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e60mm main piping:\u003c\/strong\u003e The Supreme SP uses 60mm (approximately 2.36\") main piping diameter — larger than the OEM Integra exhaust. The increased diameter reduces exhaust backpressure, improving exhaust gas flow velocity in the upper RPM range where the B18C1 (GSR) and B18B1 (LS\/RS) benefit most from reduced restriction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraight-through muffler core:\u003c\/strong\u003e GReddy’s Supreme SP muffler uses a perforated straight-through core design — exhaust gases travel in a direct path through the muffler rather than being routed through baffles. The perforated core and absorption packing produce a performance exhaust tone that retains low-frequency character without the tinny or raspy quality of straight-pipe or cheap mufflers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolished dual-wall tip:\u003c\/strong\u003e GReddy’s signature polished stainless dual-wall tip. The dual-wall construction insulates the visible tip surface from internal exhaust heat, keeping the exterior tip cooler to the touch and maintaining the polished finish longer than single-wall tips.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCat-back configuration:\u003c\/strong\u003e The system connects at the factory catalytic converter outlet and replaces all components rearward — mid-pipe, muffler, and tip. The factory cat is retained, preserving emissions compliance in most jurisdictions. All factory hanger locations are utilised for a clean, rattle-free installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eGSR vs LS\/RS — Application Notes\u003c\/h3\u003e\n\u003cp\u003eThe 10158218 covers two distinct trim configurations of the DC2\/DB8 Integra:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2000–2001 Acura Integra GSR (B18C1, DOHC VTEC):\u003c\/strong\u003e The GSR’s B18C1 produces 170 hp from the factory. The VTEC crossover at approximately 5,800 RPM creates a distinct power delivery characteristic that the Supreme SP’s reduced backpressure complements at high RPM. The 2000–2001 year range for the GSR reflects the post-facelift DC2 exhaust configuration — 1994–1999 GSR owners require a different GReddy part number.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1994–2001 Acura Integra LS (B18B1, DOHC non-VTEC):\u003c\/strong\u003e The LS’s B18B1 produces 142 hp. The full 1994–2001 production run is covered for LS models. The Supreme SP’s power benefit is most noticeable in the midrange on the non-VTEC B18B1.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1994–2001 Acura Integra RS (B18B1):\u003c\/strong\u003e The RS shares the B18B1 engine with the LS.

The rear exhaust exit configuration is shared between coupe and sedan on the DC2\/DB8 generation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSound Character\u003c\/h3\u003e\n\u003cp\u003eThe Supreme SP is specifically calibrated for street use — GReddy’s muffler design prioritises exhaust tone quality over maximum volume. The result on the B18 platform is a deep, resonant performance note at mid-to-high RPM that becomes more pronounced above the VTEC crossover on the GSR, while remaining composed at highway cruise RPM without the drone characteristic of straight-through designs. This makes the Supreme SP appropriate for a daily-driven Integra where interior noise at cruise speed is a consideration.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eCat-back replacement on the DC2\/DB8 uses the factory catalytic converter outlet flange and all factory exhaust hanger points. Standard installation on a rust-free vehicle is straightforward with basic hand tools — penetrating oil on the factory mid-pipe flange hardware is recommended, particularly on higher-mileage vehicles. No tuning or ECU modification is required following a cat-back installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e2000–2001 Integra GSR only (not 1994–1999 GSR). 1994–2001 Integra LS and RS.
