I was browsing summitracing equipment and found the dynomax 17315 single exhaust system for $169.99. In the "fitment" page, it says the exhaust will work up to 2004. What has changed on the Ranger from '04 to '05? Would I still be able to take advantage of this offer? I'm hoping this will work out because other similar single exit exhausts fit 1998-present. Thanks guys!
