I'm sure many will recognise this?
When starting from cold(or even warm) I can hear the exhaust flowing in the system as a sort of spitting sound, the sort of thing you get after fitting a new system and the internal surfaces are still clean? It goes fairly quickly as it warms up.
The system (3"Milltek/GTspec headers/Harvey up-pipe) has been on a fair time but the noise became more noticeable recently.
I've been under the car and can see no evidence of leaks or blows. I did suspect the slip joints in the headers and up-pipe but can see no evidence although of course, they are wrapped.
I know the sound I'm describing is not uncommon with tubular systems, it's just that it seemed a bit more noticeable recently

Only thing I can think is a leaking gasket, why not get someone to give a little throatle while you double check

Mine on my back box is driving me up the wall, keeps coming loose, going to have to add springs when I get the chance
