This is my 2007 saleen S281 mustang. I purchased it new, & started modding it about a year and a half later. I started off with a C&L racer intake, Brenspeed custom tune, American Racing longtube headers, American Racing O/r H pipe, Dynomax bullets, 373 gears, & 315/35/zr20 nitto nt05 as the rear tires. After this i made 310 rwhp & 309 ft lbs of tq. I wasnt quite happy, i wanted more than the usual bolt ons So i purchased Comp cams spr xfi stage 2 cams, zex blackout kit 125 hp jetting, & tci streetfighter tq converter. I havent ran it at the track yet, but come spring i will open her up to see where i stand. I love this car. & love mustangs in general.
