dont knoq if this is aus wide or just vic but the exchuast must exit a certain distance from the last opening of the vehicle and before a certain date i think about 88 ican exit any side but past that date it has to exit at the rear or drivers side. that said mine is a stiaght pipe out the dumps downwards under the drivers seat. it comes down and crosses under the chassis behind the rear spring pearch and the runs along the side of the chassis. when i do my bodylift in going to get pass between the body and chassis.

also if its coming out the sides it has to be facing between 15 degrees down from horizontal and 45 degrees down from horizontal. and as previously noted, it has to extend 40 mm rear from any adjustable windows, but musnt extend the overall lenght of the vehicle (ie doesnt hang out past the bumper)

If you are dumping out the side you have to have it on the driver side only but considering you have rear doors im sure you have to run it all the way to the back so you can't get exhaust gasses leaking into the cabin.

Side pipes are only legal on utes as far as i know.

BTW- no muffler on a non turbo would be quite loud i recon. :twisted:

MY exhaust exits on passenger side and is legal....

Te rear section of the vehicle - last 30cm or so - is classified as rear so even if it points out to left it's still considered "rear" and is legal.

This is an extract from the ADR on exhaust outlets. MC = Wagon, N = Ute (generally speaking). Good starting point.


11 EXHAUST OUTLETS
11.1 Enclosed LE vehicles, and MA, MB or MC vehicles must meet the following requirements:
11.1.1 the exhaust outlet must extend at least 40 mm beyond the furthermost outboard or rearmost joint of the floor pan which 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;
11.1.2 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; and
11.1.3 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.

11.2 Omnibuses (MD and ME Vehicles)
11.2.1 the exhaust outlet must be as near as practicable to the rear of the vehicle;
11.2.2 except in the case of vertical exhaust systems, the exhaust outlet must discharge rearwards or to the right of the vehicle, either horizontally or at no more than 45 degrees downwards, and must not extend beyond the perimeter of the vehicle when viewed in plan; and
11.2.3 when the exhaust outlet is vertical, it must be located behind the rearmost portion of the passenger compartment and may discharge either vertically upwards or rearwards at any angle above the horizontal.

11.3 N-Group Vehicles must meet the following requirements:
11.3.1 the exhaust outlet must be behind the rearmost seating position and at least 40 mm beyond the furthermost outboard or rearmost joint of the floorpan which is not continuously welded or permanently sealed, and must not extend beyond the general perimeter of the vehicle when viewed in plan. In the case of permanently enclosed vehicles not fitted with vertical exhaust systems the outlet must extend to the perimeter of the vehicle when viewed in plan;
11.3.2 the height of the outlet must be either greater than 150 mm above the maximum height of the cab or less than 750 mm above the ground;
11.3.2.1 for above-cab exhausts, the direction of discharge must not be to the left of the vehicle and must be above the horizontal ;
11.3.2.2 for other exhausts, the direction of discharge must not be to the left of the vehicle and must be between the horizontal and 45 degrees downwards; and
11.3.3 any exposed section of an exhaust system discharging above the cabin must be shielded to prevent accidental personal contact in areas where contact can occur during normal operating and servicing conditions.
11.4 Vertical exhaust systems, where fitted, must meet one of the following requirements:
11.4.1 the orifice must be a horizontal cross-section of the exhaust pipe and must direct the exhaust gases vertically upwards; OR
11.4.2 the orifice must be a horizontal cross-section of the exhaust pipe and must be fitted with a rain cap such that in plan view the hinge of the cap makes an angle of 90 degrees ± 10 degrees with the longitudinal centreline of the vehicle, with the rain cap operating in a fore-and-aft direction; OR
11.4.3 the orifice must be angled and orientated so that the principal flow of the exhaust gases is directed rearwards, within 0o and 45o the longitudinal centreline of the vehicle.

Well you can't ask for a more complete answer than that!
This is not legal advice.

Do you have a modification plate for the reduction in seating capacity from 4 or 5 down to 2? If so that would make it a N category. Excuse my ignorance but what exactly is your 'Middy'?

Here is how the categories are defined:

OFF-ROAD PASSENGER VEHICLE (MC)
A passenger vehicle having up to 9 seating positions, including that of the driver and being designed with special features for off-road operation. A vehicle with special features for off-road operation is a vehicle that:
(a) Unless otherwise ‘Approved‘ has 4 wheel drive; and
(b) has at least 4 of the following 5 characteristics calculated when the vehicle is at its ‘Unladen Mass‘ on a level surface, with the front wheels parallel to the vehicle’s longitudinal centreline, and the tyres inflated to the ‘Manufacturer‘s’ recommended pressure:
(i) ‘Approach Angle‘ of not less than 28 degrees;
(ii) ‘Breakover Angle‘ of not less than 14 degrees;
(iii) ‘Departure Angle‘ of not less than 20 degrees;
(iv) ‘Running Clearance‘ of not less than 200 mm;
(v) ‘Front Axle Clearance‘, ‘Rear Axle Clearance‘ or ‘Suspension Clearance‘ of not less than 175 mm each.
OMNIBUSES
A passenger vehicle having more than 9 seating positions, including that of the driver.
An omnibus comprising 2 or more non-separable but articulated units shall be considered as a single vehicle.
LIGHT OMNIBUS (MD)
An omnibus with a ‘Gross Vehicle Mass‘ not exceeding 5.0 tonnes.
HEAVY OMNIBUS (ME)
An omnibus with a ‘Gross Vehicle Mass‘ exceeding 5.0 tonnes.<P12>
GOODS VEHICLES
A motor vehicle constructed primarily for the carriage of goods and having at least 4 wheels; or 3 wheels and a ‘Gross Vehicle Mass‘ exceeding 1.0 tonne.
A vehicle constructed for both the carriage of persons and the carriage of goods shall be considered to be primarily for the carriage of goods if the number of seating positions times 68 kg is less than 50 percent of the difference between the ‘Gross Vehicle Mass‘ and the ‘Unladen Mass‘.
The equipment and installations carried on certain special-purpose vehicles not designed for the carriage of passengers (crane vehicles, workshop vehicles, publicity vehicles, etc.) are regarded as being equivalent to goods for the purposes of this definition.
A goods vehicle comprising 2 or more non-separable but articulated units shall be considered as a single vehicle.
LIGHT GOODS VEHICLE (NA)
A goods vehicle with a ‘Gross Vehicle Mass‘ not exceeding 3.5 tonnes.
MEDIUM GOODS VEHICLE (NB)
A goods vehicle with a ‘Gross Vehicle Mass‘ exceeding 3.5 tonnes but not exceeding 12.0 tonnes.
HEAVY GOODS VEHICLE (NC)
A goods vehicle with a ‘Gross Vehicle Mass‘ exceeding 12.0 tonnes.

Same here in SA apparently. My wife has a Hiace 13 seater bus she drives for her work, I noticed it's got a compliance plate for having two of the seats removed.
