Back Box

[christurner291]

hey guys and gals just wondering what is required when fitting a new back box is it a job you can do at home with a jack or does it need to go to a garrage ?
cheers

Standard backbox or an aftermarket one designed for your car? or a universal one? If you have some mechanical knowledge you'll probably be alright to fit a standard or one designed for your car, may need a new clamp etc, if it's a universal one you're more than likely going to end up welding.

1. Put the car in gear + chock the front wheels
2. Jack the rear of the car up
3. PUT AN AXLE STAND UNDER EACH SIDE
4. Spray some WD40 etc onto the nuts + threads of the old clamp (to help the nuts undo)
5. Undo the nuts
6. Take the old back box off of its hangers
7. Put the new back box onto the hangers (may need to bend the mounting points on the back box if they do not match up correctly)
8. Seal up the connection between the joint of the middle section and back box with exhaust paste
9. Tighten the new clamp a little bit each side (don’t just completely tighten one side then the other)
10. Take the car off of the axle stands + tidy up

Done!
