Thank you. You have rated this product.

Miata Muffler with Dual tips by Borla. The Borla name is synonymous with performance exhaust. This Miata muffler commands attention under acceleration and mellows out under normal driving. Installation of this Miata muffler is easy...but not a bolt on. 50-state emissions legal with a 1-million mile warranty.

This is the last of these, uses a Borla race muffler so you know the sound is AGGRESSIVE, best for a customer with stock header and stock midpipe in our opinion.

Last one in stock because Borla bumped their prices to something like $700 and that was just too crazy for the Miata market so this is the last unit at the old price for NB Miata. YES, you need to cut lower bumper for the outlet on the driver's side!

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

I have to say that your website is one of the cleanest, most functional and easy to use. There are a lot of independent part sellers that have horrible websites and it was a joy to use yours and even explore the customer car gallery and the good win build page. Thank you for a great experience.
