MBS answered all my questions promptly. Spec Miata exhaust was shipped the same day I bought it. Got here quickly. Definitely a Quality product. Looks great, fits great, and sounds great.
We just installed this a couple days before our first ChumpCar race. Everything for install was included and install was very easy and straightforward. Exhaust had a great sound and was loud, but not too loud. The tip was very close to the bumper, so you may need to notch it a bit. Great price, great product, I couldn't be happier.
