i have the WS on my coupe. i love everything about it... except for two things. the tip sit kinda behind the bumpers like the oem skinny exhaust. secondly... the pipping flange from the mufller to the B pipe touches the gas tank. i've called apexi and they said that it was designed to only have 0.25" of space... but i ask WHY? anyway... i told them that everything seems fine till you start bolting them up. then the flange will eventually push against the gas tank... which is something i am not gonna risk. therefore, like others have suggested... use a rubber hanger and stick it in between.

well, i did that and then it fell off. so i decided to DIY that mofo so it will stay. i cut a slit in the middle of both sides of the rubber hanger... the shorter length part. then i stuck one of those 3" metal adjusting thingy (the one that you use on the cai to the TB.) and then wrap it around the pipe. then... presto! it stays in place and now you have .75" of space and definitely would not go anywhere near the gas tank.

other than that... i love the way it sounds... it's quiet and could be loud when need be. plus i think it gives me better torque and pick up speed compared to my old greddy evo.
