Raw catalytic converter with unwelded ends so that you can have your local exhaust shop cut out your old cat and weld this replacement in. ONLY for those who have our RoadsterSport midpipes for NC (2006-2015) or ND (2016+) MX5.

Note most of our RoadsterSport midpipes are available with either 4" or 5" cats - and some only come with one or the other.

Make sure you know which size cat your midpipe has before ordering a replacement!
