Well i only paid $18,500 for my 99 camaro.
The mod si have are
Headers and true dual exhaust all the way back (just cats no muffler) $450
Stage 2 port on the heads $400
whisper lid and computer program module $300
NOS $450
12 bolt rear end $1000
Subframe connects $200
I run 11.6 @118 m.p.h. in the 1/4 mile
The tires i run are Nitto's 315 on the back and Yokohama's on the front.
Next month i will be adding a Vortec supercharger with intercooler.
But as my car is right now i dog out Mustangs all day long,i raced a Mustang last Fri who was running a supercharger with 8 psi, and he could only hang with me through 2nd gear.
The reason there are more mods out there for Mustangs is because they need them to keep up with the CHevy.
Sorry but its the truth.
