i had a 60 series (i think it was, i know it was the one made for 4 cylinders), on my 240 for a couple months. sounded awesome. everyone liked it. i eventually got cat-back so i had no need for it anymore. i have the muffler still, its 1 in 1 out though, u can have it for cheap if u want, its just sitting around, might have a little rust on the outside, nothing big though, let me know.
