Miata 1990-2005 · Miata Exhaust & Mufflers · Catalytic Converter


Miata catalytic converters often clog with age and choke off performance. If your Miata won't accelerate strongly in the upper RPM range it may be a failing catalytic converter. Note that the 1990 through 1997 Miata came with a bolt in catalytic converter but the later 1999 through 2005 Miata had a converter welded into the exhaust midpipe.

REVIEWS

I received great help from Good-Win on choosing these wheels and tires and the cost + shipping was very nice, but the help you get here is worth any cost.

Hi There Good-Win Racing. I just wanted to thank you guys so much for the great customer service and quality parts. My 91 MX-5 is running awesome thanks to the parts I put on it from your website, racing beat sway bars, racing beat endlinks, racing beat muffler, magnaflow catalytic con, shifter parts, and a few more. Thank you so much for making your website so knowledgeable and easy to get all these awesome MX-5 parts. My MX-5 handles, drives, and sounds awesome with all the new parts, Thanks a Million!! I look forward to ordering a new exedy performance clutch and light weight flywheel from Good-Win Racing in a couple months.
