Are you running an S14 rear subframe? That would give you an extra 10mil push outwards. I always forget that S13's have shallower fenders compared to S14's.

If you want to I have a spare S14 subframe and RLCA's if you wanted to go that route. It will give you better traction with all the V8 tq of yours. haha

As for the exhuast I figured I'd just cut off my current tip and weld on a Stainless 3.5" turn down and cut the angle to make it look pretty much like that FD. I dont see a point in buying a whole new muffler for just a difference in the way the tip looks. I like the way the megan muffler sounds.
