If you want to fix it cheap, find a competent welder/welding shop. Complete aftermarket system will run 500.00 & up. Or you could place an add in the "wanted" forum. You could also look on e-bay.
MrGixxer, thanks for your info cause I need to source from salvage area,as for OneWheelRider my place don't have a competent person to do the job cause, their main reason is they don't have proper tool to bend the piping.
