Two main questions to be concerned with on an exhaust with a FI set-up. 1) Piping size and 2) straight through or chambered muffler(s).
If it is straight through (Which I doubt) and it is 2.5 inch piping, it could still support around 250 WHP. Plus or minus some ponies.
If it i chambered then I would think it would lower that number a tad.. but it all depends on how the muffler is designed. Being a fairly quiet exhaust, I would bet the muffler is pretty "muffled", but I could be wrong.
Another possibility is getting the muffler replaced with a straight through style muffler when the time for the turbo build comes.
