Hope you have your problem solved . I've had a similar bizarre isuue for a while. I'm stage 2+ mind but one day I'll go for a spin and the car will be epic absolutely fantastic big smile etc. then if I go for a drive very next day there is something missing still very quick but just something not quick right 1/2 sec more lag, lower top end power etc. I've never go to bottom of it. Never any fault codes recently changed dv, n75, plugs, coilpacks. Anyone any ideas? I know I need to get a data logging session done but sods law it will be on a fine day.

Have you tried logging  your maf sensor readings as that may be on its way out.

Ah nice been there a few times, last time was a couple of years ago with a VIP for Team RAC was very enjoyable.

Jason Plato just edged it against Carl Turkington (Team RAC)

Weather was lovely.

Well finally got round to getting a garage to fit the part I got off VRS, and sadly it didn't fit they garage told me, apparently this has a small bend after the flex and my GTI has quite a large bend making it incompatible, however the same diameter.

I am however getting him to weld them up together with a sleeve over it that should do the trick, so not a huge great deal.

be glad to get this noise sorted!!

Ok so had a local place fit the new downpipe with pre cat removed and if anything it;'s now worse.

The sound is evident on idle, it sounds very metallic, and then every time I release the revs it happens and now it's really loud.

Could it be the main cat its self? Sounds like loose metal mesh that's being ripped around every time I let off my revs.

Going to take it back to the garage on Monday to see what they say, but I'm now thinking turbo or cat etc? Performance is down, takes a while to spool etc, but I;ve bought a new diverter valve just in case also.

....One way to check the cat is to fist the box [that doesn't sound quite right!] - I'll rephrase that: Hit the cat enclosure with the side of your fist and listen for any rattling inside. Obviously wait until it's cold!

It shouldn't rattle.

I get a little more resonance (or loose mesh as you described it) with my pre-cat removed. Garage checked the system for leaks and put the sound down to the pre-cat being removed.

Whilst with pre cat removed it does sound throaty, This is defo a fault problem.
