Re: twin pipes
so does it matter how long it is? could it only be like 40mm apart?

any length ya like, coz it will make it sound better.
although if you were get it all into a single pipe to exit the truck, then that would sound even better still

Re: twin pipes
there should be an small performace gain from adding this if your pipes are the right size
without going into harmonics and a loooong droning speach there is a piont on the single pipe where the pressure waves and resonance build up (will cause more heat here as it is stalling the exhust gas) now if you jion to the opposite pipe it will let this build up flow accross and its an easy one to locate you just use the heat, paint your exhust with some paint and run it at running revs 3000-4000 (becouse harmonics wavelength changes depending on revs)... anyway there will be one spot that heats up faster burning the paint, thats your piont you want to put the H pipe in
And yes shorter is better
