okay so ive now replaced the gaskets for the downpipe ( with new downpipe)to turbo pack, downpipe to center pipe and center to catback(I thought it might be an exhaust issue) and im still having problems.
The rattle seems to be getting worse and i can hear it while on tick over, its fine when i accelerate but soon as i lay off the throttle / change gear there it goes again, it sounds like its coming from down near the twins but i cannot pinpoint the issue. The thing is, its only started doing it since i removed the air pump. :Grrr and now im starting to run out of idea\'s :(
any help would be very much appreciated !!!

If its a single conversion, it could be one of the blanking paltes under the plenum
Have a good look at all of the heat shields,probably one of them is touching to make the rattling noise.
