I don't think the tuned pipe would be essential. Even though I don't think we have the tuning optimised yet I haven't found it to be overly sensitive, its pretty light and keeps the noise down (nowhere near as quiet as Scott's YS though!)

You could certainly buy a genuine Hyde mount and I did talk to Merle about getting one but unfortunately the size wouldn't fit in the space we had to work with and the price didn't fit into my budget. I cant compare the one we made to the genuine Hyde but it does seem to be working ok so far and made a noticeable difference compared to hard mounting.

Alternatively you could look at something like the isolation mounts shown in Claude's post on the previous page, we will probably try one of those setups in the future but had trouble sourcing the bushes during this build, I believe now the ones we were looking at are back in production.
