From the EAS box (red tag) along the top of the chassis rail inside a protective sheath on mine. Check that you don't have a blow in the exhaust, it's unusual for the pipe to fail unless it's been melted.
its ok, the pipes not broke, i took it out the airbag and ran a pipe straight to the valve block outside the car and thru the bonnet, just to test, my problem lies with the diaphragm i believe check my other recent post.
