Right loosened the jubille clip and wiggled the pipe and I straightened it up and got it on a bit further. Then took a trip to my private run way and did 3 runs taking 2nd and 3rd gear to 4k revs and all was fine. Almost got to 4k revs in 4th but started to run out of runway (it's only a little airfield

)
Engine felt a lot more solid and the mpg figures hardly moved where as before the figures were all over the place.
I'm loving the new coolant bottle too! Just need to tidy the rest of the engine bay up as well now. Should hopefully be able to do my gloss black roof and interior trim on wednesday so the car should look a little better soon.
