I've got a '01 Mustang GT auto and I've got about 2-3K to spend. I need performance mods. I am stock except for K&N filter. I was thinking about doing some exhaust work first. ModularFordPowerhouse.com says that their Dr. Gas Offroad X pipe with BBK long tube headers can net atleast 40 HP. Doesn't that seem kinda high? On a completely different note, I was thinking of getting their forged rod and pistons kit for $1400 and getting a cheap dry nitrous kit and just running a huge shot safely on the forged motor. What do you guys think? I was thinking of just skipping all the expensive little mods like t/a adjuster, pullies, CAI, and throttle bodies altogether since they hardly give anything.
