This translates into a more stable platform for delivery of power to the rear wheels. The Miata PPF power kit aids reducing the intensity of the '65 MPH shimmy'. Fits manual transmission only.
Roadstersport II was a great purchase, easy install, and sounds great.
Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!
