These people make a good range of stainless silencers at a reasonable price. If you are Ok with a side exit at the rear of the silencer, they also do a range of angled bends at various degrees.

If however you want an exit pipe that runs from the silencer to the rear of the car it requires a bespoke pipe as it has to run close to the rear tyre without hitting it or the chassis.
Other sources are Melvyn Rutter (excellent service - no connection other than being a satisfied customer) and P D Gough from whom I bought a silencer and rear pipe for my '54 Plus 4 in 2009. Just looked up the price: £322, argh!
