We checked our manifold and downpipe joints but they are tight and there is no sign of leaks.
The new silencers from Seven Workshop have the inlet the same diameter as the downpipe. I have fitted a sleeve over the joint but it is not very satisfactory and I shall try to improve it today.

Jamie told me of this problem and supplied a suitable sleeve. I used exhaust paste (as I always do) when assembling the system.

I have remade the joint between downpipe and silencer and had a short test run. The popping back has gone but it did manage one backfire on the overrun. That is probably a leak close to the engine though I can see no signs of one.

I spent a while last night cleaning and re-cementing the join between the downpipe and silencer. There was no significant evidence of a leak but it'll be another possible cause ruled out. I'll test it this evening; I have an old school friend visiting who has just bought (but not yet collected) his first Seven. I've a feeling he's going to expect a driving lesson.
