Exhaust blowing, is a patch any good

[barker22]

hi guys, ive recently just noticed my exhaust blowing, theres a slight whistling sound whilst cruising but when the taps are opened i can hear it quite loud. ive bin underneath it and i can feel the gasses escaping near the 2nd lamba sensor on top of the exhaust. how good would a patch work, obviously its only really temporary but whats best, paste, bandage. bearing in mind its a PITA place being on top of the exhaust.
cheers guys, terry

Nope, they're shite.

i think the lambdas come with little sealing washers, although they might be captive - worth taking it out and cleaning/refitting with copper grease?

ed. sorry - it's not actually leaking from the lambda? is it leaking from a joint, or corrosion?

it is leaking between the lambda and the silencer. the whole exhaust is rusted neway and needs changing but just wondering if a patch would last for say a month or 2 and if so whats best.

there's a joint between them - is that where it's leaking?

182 cat's not difficult to remove, so could treat it to new gaskets either end and look at welding the damage (if poss - need pics)

no its literally just after the joint about an inch and a half from the silencer, but as said its on top of the pipe so not very accessible without dropping it.

The joiny between the cat and centre pipe always leaksin my experience, it is a crap design.

I cut mine off and welded a 3 bolt flange in its place and opened it up to 2.5 inch

it's fine if you renew the clamp. Clamp gets deformed and doesn't like being re-used
