[Liveware Problem]

Nice, bet it sounds good too with that stubby?

[Neal]

Yes mate it's certainly got a grunt

Put a home made baffle in to make it quieter and

Have some back pressure

Sounds sweet tho

I'm not mechanically minded at all, what is the purpose of back pressure?

Not sure, but I think it's like this: when the exhaust valve opens and the piston begins to force the exhaust out of the cylinder, the piston is designed to experience a bit of resistance (i.e. back pressure). If it's not there I guess the piston could experience unbalanced forces during the exhaust cycle and (and this is where I get hazy) not run well. When you fit a short exhaust or remove a baffle you reduce the amount of back pressure. You can get away with some leeway, but the engine will run more smoothly when the back pressure is close to what was designed.
