hi all

looking for advice on making an exhaust for a 26cc engine side mounted pits style exhaust? i have a tight space to work with hence make it yourself, off the shelf pitts exhaust would do but i cannot find a side mount exhaust to fit the engine no choice but to make it

the original exhaust is a piece of dog poo,

i have paid £10 for some 50mm, and 19mm 16 gauge tube and sheet for end-plates, to make a barrel type exhaust i intend to use aluminium solder rods, but was thinking about silver solder?????

advice here please !

small tube for the baffle and possibly the exit as well?

the only thing is i need to make a 10mm exhaust stand off to match the opening not sure on technique but i could get this milled out of 10 mm flat bar or block?

advice here please?

Richard,a lot of shops,such as the pound shops etc,sell a range of stainless steel salt and pepper pots.This will give you a ready made canister,which can be silver soldered with pipe and the like.You will have to fill the letters P and S (usually perforated in the lid),with silver solder.Go to your local Wilkinsons or such like with a tape measure and also check the weight before buying,some are very heavy.

Best of luck Barrie B

Use the 'silencer' you've already got as a header, then a bit of pipe to one of these...
