I have taken my car in for an exhaust due to the rusting problem so that if it does rust again it should be under the guarantee, but the thing is it is still blowing and i keep going back to the guy that did the job and he says its the flexi pipe (which was also replaced by the way) and its normal for them to blow somehow i dont think so cos its affecting the perfomance of the car is there some sort of motor agency or somethingf i could report him to i am sick of having the run around with him now!

I had the same problem the other week. Turned out that that the exhaust was becoming loose at the manifold due to vibration, put an extra nut on each thread to act as a lock nut and has been fine since.

Hope this helps!

thanks will try that.

when a new exhaust fails quickly i always check the engine and gearbox mounts, play in the mounts puts strain on the exhaust, especially under acceleration/decelleration. it isnt the exhaust fitter's fault if that is the problem.

he is also not completely wrong when he says it is normal to get a slight blow at the flexijoint. on the bravo/a range the flexijoint is a corrugated layer type, this will leak very slightly from new, however it is VERY slight and should only just be noticable by hand.

the problem with corrugated layer flexijoints is that they are fairly fragile and easily damaged during fitting. the layers are flexible, but they can be bent permanently if a lot of force is put on the joint. once bent, the layers will allow unacceptable leaking.

a leak at the flexijoint will give the lambda a false oxygen reading, making the car overfuel, giving bad performance.

i would get an opinion at another garage first, then go to your local citizen's advice for help with what steps you can take next.

Thanks Jug i was just getting really fed up as i have taken the car back about 5 times in the last 2 weeks all because of the poxxy exhaust and im geting rather annoyed.
