Thank you. You have rated this product.

RoadsterSport High Performance replacement catalyst for your Miata at one third of the cost of the smaller diameter dealer units.

YES...CARB Exempt for OBDII, (NEW CARB CORE 448005).

YES, includes gaskets and hardware!

Yes, bolt holes are slotted so you can squeeze this 2.5 inch diameter unit into the factory space... but it has the flow for use with any of our performance Miata exhausts from RoadsterSport to Racing Beat, Borla, etc.

Made in the USA, All Stainless Steel flanges mean 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).

APPLICATION NOTES FOR UK cars...UK MX5s with a 1996 P registration or later may require the use of a RoadsterSport or other aftermarket exhaust to use this catalytic converter. The factory cat on those Miats is longer (475mm instead of 440mm) and the exhaust system is not compatible with our cat.

I should thank you. The parts ordered have greatly enhanced my MX-5 and they were received well before I could have reasonably expected them. I'm an enthusiastic new customer. Regards, John

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.
