It will kick in from about 10 seconds when i accelerate harder. You probably need to turn speakers up.

This has only started happening since i had to remove the downpipe to manifold and engine sump because of torx bit falling in engine :/ .

It happens when i accelerate more and is a nasty noise.

I do know i have a major blow where the downpipe meets manifold now as bolts are nakered , but this is the only thing i know which has changed. Noise was not present before.

Can this noise be the exhaust down/mani blowing ? It sounds like nasty flapping sound and reminds me of years ago when i blew headgasket and engine sounded all metal ping pongy :/

Kinda sounds like blowing where the manifold meets the head to me, my vtr sounded similar when it was blowing there but not as loud because it was only slightly blowing

No i have a massive blow where the down pipe from the decat meets the bottom of the manifold as the studs were nakered when i removed and tried to put back together but it has not went on right and big leak their but dont get paid till next week to sort that out....but im trying to eliminate it isnt a costly engine problem :/ so if anyone recognises the sound appreciate the comments, its a constant flapping noise that gets worse depending on the gear im in and revs i give
