Exhaust There is 1 product.

Your Miata factory exhaust does a great job doing what it was designed for - keeping your neighbors happy. That works well, until we want more performance. A Miata engine, in its simplest form, is like an air pump. If you can gain efficiency by air moving through the engine, you have increased power. An engine builder will always claim to open the exhaust up before the intake. Before we can add more air in, let's let more out first. A well thought out performance Miata exhaust upgrade will release some of that hidden power and increase performance, while lowering lap times.
