email is the best way to get hold of Roger at Harpers there is only 2 of them there and one travels a lot, Steve is hands on the tools.
I've got a dual Librands on mine and it's noisy enough without driving you mad on a long run.
Somehow the side exits lose the V8 sound to me as you just hear 4 pots very close to you and miss the others (On a dual system).
