Exhaust Exit Laws

[Scribble]

Hi does anyone know the laws on where an exhaust has to exit on a car? I have heard it can be anywhere after the rear doors.

I have seen utes etc with the exhaust that runs up through the tray, behind the cab and look like truck exhausts sticking up above the roof.

Does anyone know the laws regarding exhaust's? Im in WA by the way.

Thanks for your time,

Joel

I THINK the ruling states that the exit point of the exhaust must be at least 1 metre past the last opening window of the vehicle.

That is why utes can have shorter pipes.

Keep in mind that regardless of the length of your pipe you are still required to adhere to noise level regulations.

• The exhaust outlet must extend at least 40mm beyond the furthermost outboard or rearmost joint of the floor pan that is not continuously welded or permanently

sealed which could permit direct access of exhaust gases to the passenger compartment, but not beyond the perimeter of the vehicle when viewed in plan.

• The exhaust outlet, if to the side of the vehicle, must discharge to the right hand side of the vehicle and downwards at an angle to the horizontal of not less than 15 degrees and not more than 45 degrees.

• The exhaust outlet, if to the rear of the vehicle, must discharge at not more than 10 degrees above or 45 degrees below the horizontal.

• All exhaust and muffler systems must be free of any leaks or mechanical faults and should be adequately supported.
