It depends on the car, its beena few years since ive been into tjhe actual car scene so ill see if i can remember any places that do it for that price..I know on my car some exhaust modification had to be done to get these things on. What kinda car do you have?
what u can do is bolt the things on yourself and then just go to a shop andhave them weld them in place...I know alot of people ththave done that. It shouldnt cost that much then since u already did most of the work...
