@MV (and everyone!
So, i brought the 30 quid flexi pipe from ebay! Had a nightmare finding a specialist, well, i didn't! A cousin of a colleague of a mate runs a 'tuning shop', so i was put in touch and went along to see this guy.
Well omg - if there was under half a million euros worth of cars in there being worked on i'd be surprised. I was in AMG heaven until i looked outside and saw my poor rattly bella looking at me with her puppydog eyes!
Anyways - flexi pipe is fixed, and the noise is gone!!!!!!! No noticeable difference in power - by my word - the noise has gone (did i mention that?)!!!!!!
The lad said most of the exhaust is rusted as f***. He took me round the pipes and the engine and showed me what was what. I was very pleased tbh, because even though he only removed the pipe assembly to weld in the new flexi pipe he had replaced ALL fixings from the manifold to the back box - just to make sure i get as many more miles out of the rest of the rotted system as i can! Top job.
The only sad news is that my heatshield did not survive the surgery
Anyone got one knocking around, as mine is now in the bin!!
