Ive had the b4 a few months now and the exhaust has seen better days i think! I have already had a section welded up as all dat was holding it together was the heat shield at one point! Now the noise is bak again as if its running a bit rough. A bit of the casing decided to coome off a few weeks ago and its also rattling. I have been using e5 so the engine is fine but i think its time i splashed out and gave the car a bit of a re-vamp!! Were can i get a decent system for a 01 B4 and not for insane money! any help appreciated. thanks
