I thought about getting a stainless straight-thro pipe made up in our pipe shop at work. Could get it done for free if i gave in a template or sample of exactly what i wanted. The only thing that put me off was that i wasnt sure about the whole back pressure thing?
Im sure i read that a scoot needs that pressure or it can burn up the valve or something? Maybe im mistaken, sure i read someone had ran their scoot with no exaust as it "sounded awesome" but others had replied about the pressure thing and told him he would burn up his engine like that. I assumed a straight pipe would give a similair effect to running no pipe?
Anyway, i just fitted a Leo Vince this week in place of stock instead, at least for now, that gives a lovely burble, my 50cc Agility almost sounds like a powerhouse now and i feel i gained a little mid-range power too (may just be the cool noise messing with my brain tho).
One thing tho, at 1st i wasnt sure i could live with the extra noise every day, i even almost got some ear plugs. Now ive ran it a few days i have got more used to it and it isnt so over bearing on my ears, i can kinda zone it out now on longer rides.
