RoadsterSport Mid-pipe 99-05
INSTALLATION:
The slip joint in the middle of this item is your friend, lube it up and adjust length and clocking position as needed (if you ignore this note and shove both parts fully together you will make it all too short and that will cause contact with the differential).

INSTALL NOTES and CAUTION!
Is your Ignition Coil weak or failing? The most common reason people buy this midpipe is that their Miata midpipe converter has failed after 50,000 or more miles. The owners too often assume the failure is simple old age, when in fact something else is failing. Failing items such as coils, fuel pressure regulators, spark plugs, valves, plug and ignition wires, and improper ECU calibrations, can cause the engine to misfire and dump raw fuel into the catalytic converter, which will cause over heating and a meltdown in the converter, and is not a manufacturing defect in the converter. If you simply replace the midpipe and don't fix the failing car then you can expect to quickly kill any replacement converter and that replacement will NOT be a warranty replacement. Therefore, please have your car professionally inspected and repaired BEFORE you install your new midpipe.
