Thank you. You have rated this product.

CARB CERTIFIED using 441004-core is CARB certified for use in California for the 1999 to 2000 Miata.

The factory converter for the 1999 to 2005 Miata is a welded in part of the midpipe (California 99-00 Miatas also have second converter in the header assembly). Complete your highflow exhaust system with this midpipe...this is the best BOLT IN midpipe available for second generation Miatas and includes a highflow converter and built in resonator! Full 2.5 inches from tip to tip in all stainless steel and CARB LEGAL. ALL the mufflers we sell for 99-05 include only the muffler and not a midpipe (unlike the 90-97 choices). So if you want the flow to connect your new high flow header to your new high flow muffler here it is...for normally aspirated to supercharger or turbo (BUT does NOT fit MAZDASPEED). All stainless steel parts means years of quality performance and all the stainless parts have a lifetime warranty (300-cell ceramic catalytic converter used on all units sold in 2012 or later includes a 5 yr/50,000 mile manufacturing defect warranty on its housing and 25,000 mile manufacturing defect warranty on the internals). CARB approved and legal in California. Not for use with Racing Beat's lower rear chassis brace.

INSTALLATION: See Forum Installation Section! 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 ignored this note and shoved both parts fully together you made it all too short and that will cause contact with the differential which you can cure with just adding some length at the slip joint).

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.

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!

I have to say that your website is one of the cleanest, most functional and easy to use. There are a lot of independent part sellers that have horrible websites and it was a joy to use yours and even explore the customer car gallery and the good win build page. Thank you for a great experience.
