3rd exhaust in less than 10k miles

I am just about to replace my back box again after about 3000 miles. The weld where the pipe from the turbo enters the back box breaks. Does anybody else suffer this or have they suffered this before? Any ideas why this might be so? Apart from the cracked weld the box looks new.

Lots of things could cause that to happen, weak or broken exhaust nounts, stress on pipe by it not fitting properly, poor quality exhaust, engine out of balance.

Flexible pipe in the J pipe is the answer I think.

I always put a flexi in but something is wrong with your to go through that many exhausts.

Hey Rob! You have a 1.6 td J pipe fitted to a 1.9tdi which is a taller engine and i have to bend the J pipe down a little or maybe too much!
Pop over if you want me to sort summit out! Bearing in mind the quality differs from "pooh" too no bad every time we get J pipe!

Well did the job myself. I got a 100mm flexy pipe from a chap called Andy Smith from http://www.xtremestainless.co.uk. He does a clamp in flexy.

My Jtube has a 60mm external diameter which appears isn't very common so Andy made me one up specially. The flexy cost me £23 including delivery and clamps. The unit is very well put together and Andys service was brilliant.

The job took me a few hours to take the busted exhaust and jtube off. Cut the jtube to take the flexy and put the jtube and new exhaust in.

Works a treat. The clamps are a bit ugly but will suffice for now and I don't look underneath all that often.
