......

Either layout needs a short flexi from exhaust flange to pipe to avoid cracking the manifold, and #2 will need a heat shield to stop radiated heat downwards. Both will need some sort of support framework making with the silencer mounted on rubber suspension.

. . as usual all suggestions welcome :thumbup:

Do you feel exhausted? :lol:

You were thinkin something like this?

And

Or really professional look with welded rod and plenty of these 3€ rubber elements?

Maybe the muffler is not too nice to weld? You have ability to make custom mounting flanges at the both end of the exhaust pipe of the muffler, maybe those would be right place to support the muffler and allow muffler heat shield to mount simply clear of it?

awemawson:
Yes Pekka very much on those lines. My preference is for the clamp on version of that flexi, but it does make the assembly overly long.

And all those suspension elements are likely to end up on a shopping list shortly :clap:

PekkaNF:
I just lash up with perforated steel strapping.....pretty good and offers good possibilities of screw mounts.

Not pretty, but fast and cost effective and spares seem to be around.

awemawson:
I've just bankrupted myself ordering 2 1/2" BSP fittings - the existing exhaust is in heavy wall pipe, and although I could replace it all in standard exhaust pipe, by the time it's turned round a few bends it works out even more expensive.

There are no local suppliers unfortunately - anything over 1" BSP seems to scare plumbers these days ! Really I want a 2 metre length of 2 1/2" with threads on one end as a tailpipe, but without buying a lorry load it seems to be unobtainable, so the last metre is going to have to be that existing flexy pipe reused.

John Rudd:
Andrew,
Are there any vehicle ( commercial or otherwise) exhaust makers down your way? I'd have thought 2-1/2" pipe in abundance not necessary the right schedule for your use but of reasonable wall thickness to suffice without breaking any more piggy banks...
