Put in the TB Stage 3 Big Bore Kit into my 09 Fiddy. Still cuts out quite a bit even after jetting it. I was told to purchase a new exhaust cuz the stock exhaust just doesn\'t cut it with the new internals and bore. Anyone got good ideas for an exhaust? Looked at bbr and chp, someone has also mentioned fmf.
