Hi all,
Just to let you know that I've changed my exhaust system, I've kept the silencer, gutted it, ie, took the baffle out and the other crap, got a KS manifold like the ones in the photo's I received, well had to silver solder it up but the bends are so nice and smooth.....
Well.... huge difference!!! The silencer was a 600rpm increase and the manifold was a 700rpm increase!!! Now I'm seeing 7600/7700... Wow!!! Huge difference.... I have six pounds more thrust!! Only thing now is that it's noisy... well noisy tips, I'm running a wooden 22x8... crap I know... Not sure now if I should get carbon 20x10 or a 23x8 prop???
