Well i thought I'd try and make a decent muffler for my blade.
I have made a couple of cans in the past for my track bike(usually the day before a track day). Also thought I should spend a little more than an hour on it this time.
I also needed a mid pipe as I didn't have one to fit the two brothers headers.
Using carbon fibre and vinylester resin.
I started to shape up a plug out of pvc to the shape I wanted for the mid pipe. I was going to make a mould off this and then lay up the pipe inside that. Knowing how long it would take and the effort it required I threw that idea away and using some polystyrene, I shaped it to the same size and shape of the pvc. Then wrapped some masking tape around it as the vinylester resin would eat the polystyrene if it contacted.
I glued up the carbon around the polystyrene shape and heated it so it would go off quicker. By the time it had tacked off(just gotten hard:blip:) the polystyrene had dissappeared(eaten by the resin esters)Lol
The can was made around a pvc pipe and some bubble wrap so it could be released from it.
Decided to glue the two together and gave them one final wrap of carbon to give a nice carbon finish.
The end cap was made out of a similar pvc pipe and some blue foam with a small pvc pipe to create the outlet. Had to be kinda precise as it had to fit inside the can with no gaps.
After countless sanding and resin coats(and 20 odd showers to get rid of the itchyness from the carbon fibres) it was ready to fit and pack.
It sounds nicer than the last one I made and looks better.
Although it looks a bit like a sv 650 exhaust.
It weighs bout five fifths of fuck all, and oh it fits:D
1 pvc mid pipe plug
2 pvc mid pipe and pvc can plugs
3 pvc end cap
4 muffler still needing finish coat
5 muffler packed
6 end cap on ready for finish coat.
