just wondering how long the tailpipe from the muffler needs to be to be legal in QLD ?

And does it sound better shortened ? < thats the main qn :)
I mean I dont want it to sound like a fart but louder ?

Note: if anyone has pics of their tailpipes being shortened post away.

tailpipe must end behind any opening window.

thats the only requirement, other than noise of course.

and whats the noise constraint ?
how would i measure that if i was to do it myself ?
or would i have to get a mechanic to measure the sound ?

need a sound pressure meter. or just use common sense.

does the length of the pipe past the muffler make any difference to the noise?

i thaught it was the length of the pipe upto the muffler that matters.
