SE3P RX-8 Mazdaspeed Ver 13B-MSP Genuine Catalytic Converter
SE3P RX-8 マツダスピードVer/MAZDASPEED 13B-MSP 純正触媒/キャタライザー

This listing is for the genuine OEM catalytic converter removed from a 2004 (Heisei 16) Mazda RX-8 Mazdaspeed Version, chassis SE3P, powered by the 13B-MSP rotary engine paired with a 6-speed manual transmission. The donor car was finished in Stratus Blue Mica with roughly 133,688 km on the odometer. The seller states the catalyst honeycomb core is judged free of cracks or breakage. Only the parts shown in the photos are included; this is strictly the catalytic converter, not a full exhaust system, and other components mentioned from the same donor vehicle (oil cooler, radiator, suspension, aero parts, etc.) are separate listings and not part of this lot.
Seller notes visible wear typical of a used part, including scratches, dirt, and some dents or scuffs, but believes the catalyst core itself is not cracked or broken. Functional condition of the catalyst has not been independently verified.
Ships from Chiba, Japan, to our Osaka warehouse and on to Pomona.
