i have the slp x and it fit like stock, great product. muffler questions are always tough to answer, its mostly personal preference. i had flows with my x and hated the sound so i switched to turbo style muffler and love it. typically x pipes sound better with a straight thru or packed style muffler and flows sound better behind an h pipe. if you want a deep roar, you wont get it with an x and flows. it will be higher pitched and more raspy. try some thing with a packed construction not chambered. just keep in mind when buying mufflers/exhaust, buy based on the sound you want not power claims. i don't care what anyone says, on mildly modified cars like ours ALL performance mufflers from major brands perform well with no appreciable power difference between brands.
