Just go to your local exhaust shop and ask them for a price on a exhaust stack to suit your vehicle (they cost more as they are usually chrome)

mate i had stacks on a 45 series ute once. 350 chev int and it was f#*kin load. too loud for me as it was right at head height when driving. ended up selling it but it did sound horn.
most systems made of mild steel but stainless steel available but costs more. got my stacks from trading post $150 for both from memory, dunno new though.

was going to say the same thing, i wanted to do this to my rig too but after talking to a few people about it ive decided not too because of the noise factor, but they look very cool

this will be on my beasty 2.2, so the noise wont be quite as bad as it sounds like you had it... i might check out the trading post and stuff.. might try and go round to the local exhaust placve hre when i get a chance too...
thx for the info... then i gotta find places for it to go under the cab without the clearance being sacrificed

Also just a note, they MAY not be legal, I know for sure they are not up here in QLD.
The regs say the exhaust must exit it the rear of the vehicle OR discharge immediately infront of the paasenger side rear tire if the vehicle has no side or rear door/windows ie: a ute.
Therefore "dumpers" or exhaust that finish at the diff are not legal either.

Queensland Transport wrote:Exhaust systems must comply with the Queensland
legislation which includes the following conditions:
• Exhaust headers (extractors) may be fitted to any motor
vehicle, provided:
– they do not foul any part of the steering, suspension,
brake or fuel systems;
– all fittings for emission control equipment
(E.G.R. valve, pipes etc.) are incorporated to ensure
the vehicle maintains compliance with Australian Design
Rules for vehicle emissions; and
– exhaust systems must continue to comply with
Australian Design Rules for vehicle noise.
• The exhaust outlet must extend at least 40mm 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.
• 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.

i think this bit means you can. as long as the tip is 40 mm behind the end of the cab.....but i could be wrong

I think you would have a hard time convincing anyone that your roof line is your floor plan

thats what i mean by reading it carefully, if the stack is behind the cab, then it is 40mm behind the last seam. it says nothing about height, and besides if the stack was that high up, you wouldnt get fumes inthe cab anyway........

There is a place up here in Townsville and I'm sure there is something like this somewhere near you. It's called Highway truck spares and I priced a 4in exhaust stack for a truck and it was $180. Weld that to a couple of mandrel bends and bobs your uncle.

It was all shiny stainless too....looked horn

Go to any old truck spares shop and they are highly likely to have em, they'd be perfect.

Those Qland regs are effin stupid!
our 323 mazda has the factory pipe exiting on the RIGHT hand side of the truck...OPPOSITE the fuel filler (this IS for a reason) but the lux HAD the factory pipe (and the after market one too now) exiting on the LEFT side of the truck!
Welcome to queensland, please leave any technological inovation or common sense at the border
