Thank you. You have rated this product.

The Boss Frog Miata "Straight Cat" is an alternative to knocking the center out of your stock Miata catalytic converter, or buying an expensive high-flow Miata catalytic converter. An unrestricted 2-1/2" aluminized steel pipe is coupled with two heavy duty flanges that bolt right up to your Miata exhaust in place of the stock Miata catalytic converter. Two models available for your Miata, the SC1 for '90-'93 Miatas, and the SC2 for '94-'97 Miatas. NOT CARB legal and never will be, therefore legal for offroad race vehicles only! SORRY, NOT FOR SALE TO CALIFORNIA RESIDENTS.

Hint...see our Roadstersport straight pipe for stainless version that includes the gaskets! MADE TO ORDER, ALLOW UP TO 10 days to ship.

First I want to again thank you for working with me on this muffler. I have almost 100 miles on it now, and it has a nice mellow sound. a little Bass, but not too much. A little louder than stock, but not too loud. Plus it is nice inside the car with the top up. I am happy so far I bought this one.

I belong to a local Miata club, and am very active with it. When Spring comes I will tell everyone how much I like the muffler, and how great you are to work with. Maybe I can get some extra business for you.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.
