99 cobra....Im contemplating getting a full Bassani exhaust (mid length headers and o/r x pipes with their stainless exhaust). I am curious what the difference in power will be between the system with stock headers and with the bassani's. I have no current mods besides drop in K&N. Will soon have the JLT CAI and probably a tune after the exhaust. I have seen many posts on this for 03-04 charged cobras, but none on the n/a 99. Thanks.
