In the catalog from BMP. They have the supersprint exhausts retailing at $642.00 for the right and left which comes out to a little more then $1200.00. If you have a 3.0 then you have to make some bumper modifications which require removing the some extra plastic around your current exhausts since the supersprints are quad dual. hope this helps. I'm trying to save up to buy them. Can't wait to hear how they sound and i wonder if they'll improve any hp?
