Exhaust silencer

[martin hunt]

For my Wolseley wasp
Exhaust silencer
1&1/4" or 32 mm inlet and outlet pipe
5" body diameter ,or there abouts
24 " long ,an inch or two either way isn't critical

Any ideas or leads for supplier would be most welcome
Thanks in advance
Cheers Martin

Just a thought , do you have a custom exhaust maker near by? Have had a few items done for agrucultural products over the years, more than likey somewhere 'boy racers" would use!.

Got a local firm on stand by to make up exhaust,but am having problems finding silencer with correct input and outlet mountings
1&1/4 " is not much used now
Yes I can used flared couplings at either end but would like to avoid this if possible

Does anyone know if the exhaust system fitted to the Morris minor is 1&1/4" or32 mm bore ?
Think I could get enough usable parts from this system if right diameter
Seen complete systems on interweb for around£80
But can't get any info as to tube dimensions

Just had email back from suppliers of the Morris minor exhaust system and their pipe is 35 mm bore
I've room in the manifold mounting flange to machine a suitable hole for this to fit into
There is enough pipe work to be able to make up,a functioningsystem ,with a little bit of modifying
Will the slightly larger pipe work cause any problems?
Looking at the manifold flange more closely it appears that the 32 mm pipe now in situ has been flared out before being welded in place
So perhaps 35 mm was the original size fitted ?

I seem to recall that I simply used what I could afford which was approximately the same size as whatever was on them, I never had any problems from doing that.
Incidentally, if you have an SU carburetor and it does not have the damper for the piston you can bore the piston ,make a damper to fit and get a bit more acceleration..
If the MPG does not matter to you you can also polish the needle which fits into the jet to get a few more horses, even a couple of thous off makes a difference,
I hope these vague hints and recollections help.

The standard Morris 1000 exhaust system used to have a nice crisp fart on the overrun .

You have been warned !

I have catalogues in work which give all the dimensions of available exhaust systems, but I am not in work until Wednesday - if you can wait.

Cheers Carl.
