Rear exhaust problems Corsa b 1.2 sxi '99

I've got a problem with my corsa..

Every now and then, the rear exhaust (or so it seems) keeps knocking and rubbing either the chasis or the road (i can't tell) and it's start to annoy me. The part is only about 6 months old. Recently i've had it put back on as i got a new centre exhaust fitted and i'm a thinking it hasn't gone back on the same way. It's more of a problem when more people are in the car.

I've checked it and it all seems sturdy and fine (always looked like it sat a bit low though)

Any idea what i can do??

It's very common

Check the mounting rubbers, if all are in place you may need to take it back to wherever fitted it and get them to adjust it slightly. It's too damn cold to be messing about with it yourself in this weather.

Back box needs slackening at the join and twisting around to move the joint further above the rear axle

Ok, is that fairly easy to do?

You should have a U clamp where the back box rear pipe joins to the rest of the system, loosen that then also take off the rubber mounts that hold the back box to the car, the rubber thingies are near the bumper towards the tail pipe side.

Easy to do but can get quite annoying if its stuck. Just use some man force and should be fine. Once you jack it up and put it on axel stands it should come apparent to you.
