Here is a link to the axlebacks from where they were purchased. http://www.steeda.com/products/mbrp_axle_back_exhaust.php Very deep and throaty, but I am looking to try something else...evidently I can't stick with an exhaust for more than 6 months. They are basically brand new and polish up perfectly. Having owned both the FRPP and Borla Stingers, as well as the Corsa's, I would say that they are slightly louder than all of them, while definitely being more "throaty" at all RPM levels than the 3 exhausts mentioned above. By far my favorite axleback to date. I'm sure I can grab some sound clips for any interested parties. $325+Shipping/Paypal fees, before I throw them up on eBay. PM me with any questions.
