Their stage 2 is awesome but you can achieve the same for alot less money
Just to give you an idea
if we package a perrin cold air, invidia n1 catback, invidia downpipe and a custom tune you are looking about 1150.00 total
if you wanted to add a cobb ap with our tune 1800 as a package deal with our stage 2 map
Here is the one we did and you can see the difference between the basic cobb stage 2 map to ours
