Well my pipes came semi bent at the tips of the connection so i had to use a hammer and a pipe too get them back round 0
, But tools you need are simple.
1. Wrench Set 15mm socket
2. Lubricant WD40 or so
3. Gear greece or some kind of lubrication too squeeze the pipes together tight. (Not Required)
4. Metal Pipe Cement Sealant for cracks if you have any around the pipe,. (Not Required)
5.A Handy Friend.
6. Anything too lift the car up, jack stands a jack and ramps if you have any to get your front wheels up.
Or a welder if you want too weld your pipes on instead of clamping them on.
