If the cat is knac*erd, get it sorted asap or you will end up replaceing the centre section of the exhaust too  :y

it would smell if if its misfiring
you wanna check the why the misfire is there first
once the misfires cured the smell should disapear unless it has knackered the cat wich i dont think it should so quick

a misfire smell would be of oil , if it was rocker gaskets, i dont know of any other smell a misfire would make, a rotten egg smell is usually the cats fubared, check the breakers on here for some to replace  :y

Mine was misfiring and smelling of egg last year. Changed just the dispack and all ok. Passed MOT/Emissions last month.

Just an update .the prob was a dis plug lead No.4,    center section of exh disintergrated (11 years, 60k not to bad a life).
So fitted new set Magnacor leads/plugs/new dis pack just incase(old looked perfect) /new hbv (old one 17k).checked breathers ect.Cat back exh system.Hopefully this will be it for a while, just need blood transfusion and skin grafts now.

Vx plug leads £100 + vat per side   :-? :o

Thanks

Could someone please explain how the misfire/cat issue causes problems with the centre section of the exhaust.
Thanks, Mike.

Would say the misfire and the center box are not related faults. Misfire caused the smell which was only really apparent because the center box was knackered so made it more smelly in the car.

I don't realy know ,my exh was quite old and during the problem started to rattle thinking it was the cats breaking lose (i think original are metal ).when i took it off from the cats the left box inside had disintegrated .Mind I also just bent the back box off the pipes so it had had seen better days.

Thanks for the replies.
Reason I ask is that shortly after experiencing the misfire/egg smell, which was sorted by replacing the dispack, a load of wadding came out my exhaust.
Exhaust externally looked very ok (4 years old from Vx) and still later passed mot. Wondered if these two things were related and how. No idea if wadding was from end or middle sections.

This stuff will block your exhaust and drastically reduce power unless you get it changed mate  :y
