I am curious about something, about to buy a DZ, who makes a header and pipe for the engine, I see macs products makes a 4 stroke system for a YS 1.20 that has a flew header mounted to a pipe, and doesnt look like it comes apart. That is what I am looking for, something like that. I want something that holds the pipe to the header with some or a lot of flexibility without a silicone coupler, is there such product?
