Having cut open my exhaust to find nothing in there and seen that others have done the same, I am starting this thread to give people an idea about what they will find in their exhausts. The key thing here is to note the part number on the exhaust before any cutting is done My exhaust has a part number of 3M...

Hello everyone. As I posted on General Chat, I am 2 stroke expansion chamber builder, and a huge fan.

I build, tested and develop...
