Outer Limits 4x4 Board

My exhaust winds itself from the turbo on the driver’s side to the passenger side, it makes the cross over from the driver’s side to the passenger side behind my transfer case and there isn’t enough space to clear the transfer case park brake assembly.

My question is, what would happen if I simply cut the exhaust pipe off at the transfer case? (at a reasonabley safe spot) so that I don’t have to put up with the rest of the length of pipe going behind my TC and all the way through to the back of the rig. I know its illegal to have less and 4 inches clearance from the cab, but I don’t drive it around town unless im heading out bush or camping and I cant justify getting an axhasut system fitted because im doing a motor transplant soon.

Please help, I really want to fit this TC park brake, im sick of parking against things.

the main thing is it must exit the vehicle well behind the rear most opening door or window

i have had to drive with an exhaust leak under my cab and i got very sleepy quite fast in the middle of the day was quite scary.

Serious?? Sh1t, didnt know it was that bad. Its a soft top (see the pic below) and the transfer case where i want to chop the exhaust is mid way along the wheel base. Do u reckon ill be safe?

My main concern was missing a muffler (what effect will that have on niose etc) and having the exhaust too short. Its got about a meter and a half from the back of the turbo to the transfer case where i want to chop it.

Thanks for ur input.

noise wont be too bad the engines are pretty quiet in the toyo diesels and the turbo will keep the sound down to. but half was along the wheelbase wont be great or legal.

can you not just mod your existing exhaust?

Thanks for that mate, great help.

I figured i might be struggling with short length only being around door handle length along the length of the car.

I wish :( all my tools/bender/welder are all at my old joint down the Gold Coast, new place in bris is too small. In addition, its a silly jap model, so the turbo and exhaust tun down the drivers side straight to my fuel tank, so even if i wanted to mod it, it would still have to cross over behind the transfer case

Do u know any other way for me to get it a little further back without corssing past the TC or moving my fuel tank to the other side?

Thanks fo that

this is what i did with my truck i did not want the exhaust under the truck so i put it just outside the rail



looks kinda cool to

jonathan

thanks for the pic mate, much appreciated.

One last question,

How'd u get it on the other side of the rai? did u go under?
If so, do you have probs with clearance?

This will only be temp fix until the motor transplant is done, but the last thing i want to do it tear the exhaust of on a rock lol

Thanks again for your input, hot looking hilux too

I think youll find it too noisy cut off at the TC without a muffler. Im not sure if different turbo will make a difference, but during my suspension work ive cut the exhaust at the front shackle and it sounds like a bloody jet taking off under boost!

hahaha sounds like fun.

I guess the only way to find out is chop it and if it screws up then i better get the bender and welder out and do the job properly.

U wouldnt happen to know of a place round bris that'll sell a decent system for the hilux or even if u (or anyone else) might have info and pics for making one up, something simple and short that pops out under the rear wheel arch, can i use tubing or is there a special type?.

it might just be worth doing untill the other motors in if i really want to run the TC park brake.

Thanks fo ryor input

i am running a 2 inch body lift and an 80series chassis so i ran over the top of the rail in the wheel arch

a mates truck has the long range tank in his lux and his dips under the rail just in front of the gearbox cross member then along the out side and it all sits above chassis

cheers

if your going to cut it it wouldn't be hard to extend it back a bit and try and make a side pipe or something i little further back

nothing better than a turbo diesel without a muffler, can be loud tho

Hey,

used an V2A aftermarket muffler and a Filter. The 1HD-T isn´t loud at all, no problem!



greetings Sönke

HDJ 80 with J4 cab and hydraulic cabin

Thanks for all the advice, very much appreciated.

Ill give it a go with oug the muffler and if it seems like im going deaf from the noise ill get the bender out and have a go at knocking a new one up.

If i get stuck along the way ill be posting again

Thanks

just make sure you keep plenty of airflow thru the cabin

i think windows up with a soft top at night is a bad idea cause lots of co2 can sneak in around the gaps more so on the hiway or doing cruising

i did not believe it until it happened to me

it will not be super loud but will sound like a turbo diesel with no muffler

heaps of whistle

probably best to face it at the ground if you can

cheers

sweet ones, will do.

I didnt belive it much, but ill take ur word on it and try it around town before i go cruising down the motorway asleep

looking forward to hearing the turbo wistle though lol

Good point, its got a downward kink before it turns to face the TC so ill give it the chop there.

Thanks again, ill post again if i run into hassles.

Cheers

You will end up with heaps of black shit under the car from the exhaust smoke. But it will sound nice. I had a 2 1/2" stainless system on mine straight through. It sounded sweet for a 2.8 turbo.

yeah kinda forgot about that.

I reckon i could bear with the black stuff for a few weeks though.

Is a straight through system cheap enough to buy or is it cheaper just to buy some 2.5 - 3 inch pipe and bent it myself?

Cheers

How often do you work/look under there. if you need to work on that area give it a wash

Move ya fuel tank to the other side and run the exhaust straight down the drivers side.

had a look again over the weekend before chopping it, moving the fuel tank seems like a little less effort than the other options.

Willy Hilux, What all is envolved in moving the tank? asside from new mounts to hold it. do i need a new fuel cap on the other side or can i run it across? and what about senders/elecrtonics?

Thanks

this is what i did with my old truck
dont move it add to it you can never have too much fuel



i ran the exhaust above the drive shaft in that truck

jonathan

mine stops under the drivers seat and i dont have any issues also makes the turbo more noticeable

ThrashLux lol that looks awesome.
If i had the space and the know-how i would be mad keen.
Thanks for the pics.

Stock $Runner, did u mean that u chopped it under the cab near the transfer case and u dont have any troubles at all??
I was keen to chop it thiss weekend but didnt find the time because i was sure that i would have to bend new pipe and spend hours fixing the pipe because of the issues was going to have gassing myself
But if ur saying that u drive around with it chopped under the cab and it doesnt give u trouble then i reckon i might just chop it tonight.

Got any pics??

mine goes about 100mm past the cross member and it dosent bother me just make sure it still has atleast one mount

mate i chopped next to the gearbox, as in just after it levels off with the car, sounds sweet and havent had any troubles with fumes in the car, im sure it is illigal tho

waz

Thanks to the both of u.

It the answer i was looking for

Im sure its illegal too, but then again i think if either of us was picked up, we're sure to get a couple fines

Thanks again for your input and advice

Cheers

I had one of my exhaust's fall off in the bush so it ended up exiting underneith the rear of the cab where the backseat passenger would sit, a mate and I drove around for most of the day like that then we both started to complain of having a headache and withing 10 minutes we were feeling really sick and dizzy to the point where I couldnt stand up anymore. After that experience I would never have a pipe exiting under a vehicle.
