Hi Gary:

Yes, from plug to baffle, straight back. Also for the 30G pipe Matt measured it as 33-1/2 inches to the end of the pipe, if you don't want to stick a ruler into the pipe.

There was a fair amount of back-and-forth about anchoring the pipe back on page 12. Final analysis is the farther back the better. Engine vibration creates less flexing of the coupler the farther back the anchor is located.

For an idea of how a commercial mount looks, check out the Dave Brown Hush Mounts. Even the large one can't handle the circumference of the ES pipe, but it gives you some idea how they might be anchored.

All my experience thus far - on my first pipe - indicates that Ed Alt's use of the O-rings at the tail of the pipe, anchored on the sides of the pipe tunnel (also on page 12), is probably the best solution.

My Velcro strips are working well now, but it took some finagling with various insulators. Ended up using some of the Teflon-impregnated fiberglass tape with silicone adhesive, the same stuff Matt uses for his header/pipe coupler, which is McMaster-Carr catalog # 76495A56, wrapped around the pipe.
