Welcome to the forum Simon. I'm familiar with the YouTube you posted--that is a truly great sounding example of what you're lusting after.

I'm in the same shape as you regarding confidence in being able to complete this project. IMHO, I believe it depends on a couple of things--one being the level of automotive/mechanical competence you possess and the other being the amount of engineering and fabrication the kit you purchase requires. As you research the kits available you'll find a wide range regarding how complete the kit is. You mentioned RCR--they do make a very complete kit. I can only speak for myself when I say I feel I can bolt together almost anything that comes with an assembly manual; it's those cases when the parts aren't in the kit and you have to "figger out" what to do and then create a unique piece to accomplish it that leaves me a bit uneasy. One nice thing, though, is that for the right size check almost any of the kit manufacturers will do a lot of that work for you.

As for "that sound", chances are pretty good that you're hearing the 180* "Bundle of Snakes" header system the GT40 kits use. The header tubes from each cylinder are "bundled" together to provide optimum scavenging, resulting in some of the pipes crossing over and being connected to the same connector as some of the pipes from the opposite side. It has a very unique and unforgettable sound. Surprisingly enough, most of the ones I see on the forum are muffled--can't speak for the example you saw, though.

There are quite a few members from the UK on the forum--keep your eyes out and you'll figure out who they are. There are also quite a few group organizations in the UK that you can join.

Good luck, and hold on--you're in for a great ride!
