People seem to use it a lot on mustangs. They seem to be really easy to make or cheap to buy.
I bought this car as a daily driver and I promised my wife I will behave and not play with it too much cause I already have a few toys :D So tuning could be fun but then to make it worth messing with it a cold intake and exhaust before the tune would be kind of a good idea.. and then maybe nicer suspension and a rear disc brake conversion and there I go again... wifey will want to kill me and start bugging haha
