Hi guys,
With some help from a few great guys on here I have modded the muffler (still need to spray the exhaust and shroud black and rivet the shroud on)
what I found so difficult was fitting the shroud between the exhaust and crank case whilst avoiding the chain brake.
I was banging my head against the wall for days trying to bend the Aluminum and get the shape I wanted and to fit so I have added a template below which may help you guys out!
You’ll need:
aluminum sheet 0.5mm thick.
3.2mm x 1.6mm aluminum rivet
Spray paint to avoid galvanic corrosion
16mm Drill bit it dremel.
I firstly removed the baffle which was harder than I thought, not wanting to drill the spot weld out incase I went all the way though (as I don’t have a welder to repair it) I used pliers, cutting disk and grinding wheel to remove it.
I then I flattened the original exhaust flaps, centre punched a hole and drilled them away.
Ignore that this was a 20mm drill (will use that when I enter the realm of porting)

After much messing around with paper and cardboard templates I got a shroud fitted
I big thank you to @drf255 and @pioneerguy600 who have helped me with the project sharing tips tricks and advice. It’s so much appreciated guys, thank you.
