as for the exhaust, why not keep your current exhaust, and get an electric cutout before the cat? uS$99 for the electric cutout, US$35 for a cutout from summit, probably not even an hour to weld it onto your current downpipe. when you want to go fast, hit a switch, thats it.
tell you what murray. ill trade you my exhaust for yours + an electric cutout? lol
