so I'm retarded: the exhaust is for 2.75".... exactly what I had on there the first time. What I did was had the shop lop off the old exhaust right before the muffler, and weld one a Borla in place of it. This time its dumped before the axle, but I may change that.

At some point I'd like to get a cam in addition to the FI, but its not going to be anything extreme enough to warrant a stall.
