Sorry for another manifold to cat thread. I've been suffering from this for a good while now. Last summer I fitted a new kit from renault and it's been fine up until the other month were now if blows when under heavy load.
This evening I got the car on the ramps but can't see anything obvious. Hand and bag around the joints and can see or feel anything blowing. The only thing I can think off is the gasket has worn causing it not to seal properly when under heavy load.
Other than the cat to centre section which I'm pretty sure isn't blowing is their any other common problem?
I have a janspeed cat back.
