Thank you. You have rated this product.

The "S" is for street. These are an old favorite of Brian's. They work great for street/autocross and very light track duty. They dust a bit but not as much as the Hawk HP Plus and the performance is consistent from street temps to about 500. For more serious duty try the Porterfield R4.

Carbon Kevlar construction. One set needed for front, one set for rear. Does not include replacement springs, clips, etc.

These fit the "sport" brakes on 01-02 years which became standard for 03 and beyond including the MSM.

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.
