Thank you. You have rated this product.

Koyo designs its radiators to take all factory spec parts which means your factory cap will fit, and your factory plug will fit, and your factory fans will bolt right on. But for those who want an upgraded new cap to go with their new Miata Koyo Radiator....here you go. Koyo Racing 1.3 Bar Hyper Red Radiator Cap raises the cooling system pressure to 1.3 bar to improve entire cooling system flow. The higher pressure cap reduces the chance of air from entering the system compared to the factory cap. It also improves the look of your engine bay

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.

I think that Brian Goodwin is the perfect example of what is good about the aftermarket industry. He is one of the few vendors that actually cares about his customers. He is the example that all companies should be trying to emulate when it comes to customer service. Not to mention his ingenuity and desire to improve on what is already a great car. I have never had a "bad" experience with Good-win-racing. Well, except for the constant temptation to SPEND MORE MONEY.
