Thank you. You have rated this product.

The Boss Frog "Straight Cat" is an unrestricted 2-1/2" pipe coupled with two heavy duty flanges that bolt right up to your exhaust in place of the stock cat.

Not CARB approved and never will be, legal for offroad race vehicles only.

YES, this will bolt up to anything your stock cat bolts up to, that includes stock exhaust and stock header and any of the aftermarket headers or exhausts we sell.

BRIAN'S APPLICATION NOTES: Unless you actually enjoy arriving home smelling like gas this is NOT a good idea for your street Miata. Also, please don't fool yourself into thinking you will get more power in your normally aspirated street Miata by going to a straight pipe. It was true three decades ago that the original pellet style catalytic converters were very restrictive, the modern monoblock core converters are NOT and making this change on your street Miata instead of using one of our highflow replacement catalytic converters is only going to get you the stench of unburned gas while you sit at stoplights.

Therefore, this mod is for the true racetrack Miatas and is legal for race cars only which may never be used on the highway.

SORRY>>>NOT FOR SALE TO CALIFORNIA RESIDENTS.

Includes gaskets and mounting hardware. MADE TO ORDER, ALLOW UP TO 10 days to ship.

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.

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.
