I think a tri-ax is closer to $200. We all know how that mod itch is a bitch, but save for some gears if you want the most bang for your buck. IMO, most of the small intake stuff isn't worth it unless you are doing it in combination with other mods ($!). :D
The Mustang Tuning catted X is only $270, but with such small cats, I really wonder how well they work. (their site says MILs are recommended)

Kind of figured the car wouldn't lower do to the nature of the springs...but dumbass at Summit told me how much I would enjoy the look and perfomance of the drag springs after the 1 1/2 drop.
If you like it and think it is what you want, get it! If it makes you happy...who gives a **** what anybody else thinks :D If it makes you feel better, look on autotrader to see what similar (if there are any) cars are priced.
