working on my zed today and i found an exhaust blow could not find the blow. so i took the hole exhaust of and striped of the lagging thats meant to act as an heat shead and found the exhaust down from the turbo bend was like a sponge. full of holes everyere, went up nissan whilst picking up new nuts and bolts ect asked for a price 595 quid. took it to me mate power and performance and he welded up a new stainless steel piece in 40 pound later and two hours on route home.

so the turbo elbows had gone? sounds like you got a good price on the solution though fella!
