My Posts This: Topic Forum | the home made one is made from steel tube and steel flat plate

you drill the flat plate to the hole spacing of the engine and then tap the hole for the retaing bolts mark out and remove the area for the gasses to pass through get a tube and slightly flatten the end and weld to the plate with a larger tube for the main chamber drill out to fit the manifold tube to go inside, cut off the manifold tube at an angle so the gasses can pass and weld the two tubes together, now make up two baffle plate and weld them inside the main chamber, drill and tap a hole for the exhaust pressure nipple to fit into, make up a smaller tube for the outlet and fit as per the manifold tube, blank the ends off, and i painted it black to tidy it up a bit
with this baffled steel exhaust it is not much heavier than the original ally one but is quite a bit quieter
the picture above is the best one i could take without removing the exhaust
