...and as some of you guys said that it is better to buy a new front section than repair old one whereas prices of welding I decided to fix my exhaust.
I bought a brand new flexi pipe. The orginal lenght is 390mm, but it cost €85 so there is no problem to buy a shorter one. I got 270mm for €45
and told to guys in the garage to weld in 120mm pipe to it and put this all together in place.

They politely took my advice and 3 hours later my car was done

Now I can hear my Mangoose properly

Cost?
€45 flexi pipe
€120 all mechanical works including welding
-------------
€165 and happy FTO owner

so... it`ll be 3 times less than new front section
I`ve just thought its worth to mention this

Cheers
