Two Step Down Pipe for 17+ Type R/23+ Integra Type S/Accord 2.0T

Two Step Down Pipe for 17+ Type R/23+ Integra Type S/Accord 2.0T

Uncork every ounce of K-series turbo power and keep your dashboard free of warning lights with the Two Step Down Pipe for 17+ Type R/23+ Integra Type S/Accord 2.0T. Hand-built from thick-wall 304 stainless, this high-efficiency replacement slips into the factory location yet flows like an open race pipe thanks to a massive 5.0-inch GESI G-Sport UHO catalytic converter (400 CPSI, EPA-compliant, rated for 1,000 hp).

Why you’ll feel the difference

• Smooth, cast-inlet merge – Integrates turbine and wastegate flow in one broad radius for dramatic back-pressure reduction and faster spool.
• CNC transition & full back-purge welds – Zero turbulence, maximum strength against extreme EGT.
• Direct-fit versatility – Bolts to the OEM or most aftermarket front pipes for Civic Type R FK8/FL5, Integra Type S, Accord 2.0T, TLX 2.0T, and RDX without adapters.
• CEL-free power – Optimized catalyst placement and volume mean you can run stock ECU mapping—no tune, no spacer, no fouler, no headache.
• Finish your way – Choose raw brushed stainless or silver Cerakote for extra thermal and corrosion protection.
• Track-day ready – Supports larger turbos and ethanol blends while staying emissions-friendly for street use*.

Included in the box
