I know this is starting to become a bit word heavy, My apologies, I don't have a smart phone or camera so have to rely on mates but I promise on Saturday there will be pics of updates!
Quick update the new exhaust system is blowing its bloody annoying and its coming from the two flanges that meet where the manifold joins the cat. Just had a crack at tightening the nuts but tiny trolley jack couldn't take the car high enough tightened one up and it seemed to help.
However I just discovered a nice big hole in the floor of the car, at least I know how the condensations getting in! Its under the drivers door and about two apples in width and one apple wide
Shouldn't be too difficult for my cousin to weld... Will have pics of this work on Saturday
