Hi guys, about to trade my f150 for a mustang gt. It is an 05 manual gt. Has Hooker headers and x piple, Has magnaflow mufflers. Also has eibach lowering springs, CAI, and motoblue under drive pully with predator tuner. Has a fully functional ram air hood from california mustang. He says stock mustangs put out about 260 rwhp, he says he had this dynoed 2 years ago and it put out 320 rwhp. Sound reasonable?
