Noise after Miltek install

[PaulGT4RC 0]

Had a full de-cat milltek system installed a couple of months ago, since then I have had a loud clicking.. rattling type sound.

It’s most noticeable on cold start in the morning when it’s idling at around 2500rpm, when its settles it’s not so loud but it remains very apparent when accelerating.. I think at the same rpm.

A mate works for Colbournes and loves his VR6's so knows a lot about them, he checked it over, exhaust seems fine and is air tight. He said its probably exhaust gas's that normally you don’t hear due to the original system being far thicker and deadening the sound.

Has anyone else experienced this or any thoughts as to if he is on the right track.. it sounds nasty, only earlier someone said how bad the engine sounds.. said it’s about to fall apart! :-(

If I remember I will take an audio sample in the morning and put a link to it.. if it helps.

Thanks in advance.

Maybe its the heat shields that have become loose and are rattling on the exhaust

Thanks Matt,

Here is the 1min audio sample.. starts off well then I moved but you can still hear the tapping sound... its very obvious at start-up and defo doesn’t sound right.

I refuse to believe its exhaust gas's.. I’ve had after market exhausts on a few cars and they have never had this effect.

Thanks for the help so far.

Sounds like the problem I had. Can you tell where abouts the sound is coming from? On mine the heat shield at the back is loose and a bit that bulges out would tap the can at low speeds. Get a hammer on it.

Other than that, are you missing any spanners? lol

Had another thought. Its not one of the bars that goes under the exhast is it? Or perhaps your rubbers are streched and flexing too much.
