Monkeywrench Racing brings you the single best performance and durability improvement mod you can add to your MR2-S. Superior quality and affordable pricing make this one a no-brainer!
This combo eliminates all 3 OEM catalytic converters and is suitable for off-road (race track) use only. If used with an OEM type ECU it WILL cause a check engine light and P0420 code, and you will fail emissions testing. See our HEADER/CAT combo for street use and a slightly deeper, mellower exhaust note with no measurable power difference vs this kit.

The MR2 Spyder has become notorious for engine failures due to oil consumption, partially caused by the fragile precats which degrade and damage the piston rings. The OEM main cat tends to hold up ok but degrades very quickly if the engine starts consuming (burning ) oil. To top it all off the two flex joints that are part of the OEM main cat pipe fatigue and start to leak, then fail altogether causing a massive exhaust leak.
Get rid of that 20 yr old OEM hardware and install this beautiful header and down pipe combo.
