I've heard that the Apexi WS is a nice unit, but I've seen a few in pics on here and I think the muffler is just too damn big. I dont think that I could ever grow to like it. Maybe I'll see if I can get the RS*R to fit(I'm a die hard diy'r) or just rig up an exhaust using the muffler off of a TL/CL type s.
