Nadine UK GTS
Enthusiast
Hi Paul, I can only speak for a GTS. We have a plastic intake restricter inserted into a stock US air box (Very nasty and easily removed by pulling air box apart, binning offending restricter, then clip air box back). An extra rear muffler, our cats and headers are as stock US. The PCM is slightly differently calibrated to account for different fuel octane ratings over here, (which obviously is best left, but only ***** 5 bhp I believe)!
Personally, I think best mods to do first, besides good tires / air pressures and regular servicing...is to let our V10's breath more easily, and make more use of what's already there! Unrestricted air box, smooth tubes and K&N filters, fit performance exhaust to include upgraded headers. Ensure no air intake leaks, and throttle bodies in sync. Also a good thing to sort brakes too (I used to cook stock pads and boil fluid). All can be done for not too silly amount of money!
ps My insurance went up by several hundred quid with the mods though!
