Exhaust problems..

Garage talk. Anything from mounting a winch to water proofing the electrics.

What exhaust do you think i should do.

one single 3'' exit before rear right wheel.

A single 2.5" with or without a straight through muffler will be more than sufficient.


Well I tried reasoning, but he likes the extra half an inch in his pipe!!!!!!! But wait, now wants two of them. I would be seriously concerned about low end torque now.

Do what the yanks do with thier Chevys n such.. twin stacks out behind the cab :P although admittedly they are like a 6.6L cummins or duratech t/diesel :) I must admit i do prefer the uniform look of twin pipes tho. Prehaps 2.5 to the diff then 'Y' into twin 2.25s or something?

That's not a bad idea, I quite like it,

I should make it go into 8 1 inch pipes coming out the back yea Go realll hill billy lol,

Could go to the tractor reckers down the road and get some tractor exhausts. what ya think?

LOL. a Y collector behind the diff somewhere into twin pipes should work ok provided you can get them fairly straight n even. Might not be the best if you were counting and relying on every single horsey, but i doubt it will make much effect on a turbo diesel

Not counting on power just the quickest way to get the exhaust out there rear!
And there no dout about it, Twins look better then singles.

And it will give it a better look wen you see a big puff of smoke come from both sides of the truck instead of one Wen you try to hooon it with :lol:

Are you aware how much exhaust pipe costs? plus the cost of bends and getting it welded correctly.

full twins infront of the wheels is fairly easy if its legal on your vehicle, although i dont hugely see the point unless you have a V configured motor so so you have a manifold on each side to start with. Twins behind the diff isnt as easy depending how the exhaust bends over/around your rear axle. But if you can get a Y under there fairly central with no harse bends it should be alright for looks.. as long as you dont go like the AE101 trueno's and have the collector close to one side so the 'extra' side is a good foot n half longer, cracks me up when thy steam unevenly on a cold morning :P

Shouldnt need to bend to much to get them arround the rear axle, The axle dosen't come cloes to hitting the exhaust if the suspension was compressed. But will have a proper look to morrow

are you really all about it looking good even though it will sound like shit and be a waste of time. Are looks really everything? are you interested in 4 wheeling and making your vehicle go better or are you interested in driving around impressing your mates and little girls :?

Running better and 4 wheeling.. What have i done to make my truck look better.. it has a half prime pain job, Does it look like im trying to make it look better lol

If i wanted to impress i my girl mates i would had just gone and got a little old datsun 120y or 1200 and SACK it out and put a nice engine in it, but no i went and got a nice HIGH truck to go offroading in

Then get it done and get out there in the mud, the rivers and the rocks and each time you get to a point where you either get in trouble or can't get any further ask why?? and then improve what your lacking you don't need to build a monster truck or do everything that everyone has every decided is good to do. On a budget work out what you like and what imrovements you need to do from there.

By no means am i trying to discourage you because im sure your one of the main up and commers but i'd hate to see you get lost building something that everyone thinks should be done and end up with no experiance and no idea how to use what you have. Good luck and for the reccord i think your doing some cook work.

What is that supoes to meen..

And i know im a bit loose minded at the moment, I can't do nothing now that i f*cked my foot up, so my mind is doing what it wants, But i do want to get a new exhaust now that ive winded the turbo up, And i really really do not want to over heat my baby surfy,

At the start it was prity much all about looks because i thought the better it looked the better it would go right..
Well no Freaking way is that tru,
Im just trying to make sure my truck dosen't over heat, And adding a little bit of look to it ha

sorry mate meant to say COOL work, if it was me and by no means do i claim to no #### all, i would be spending money on suspension, lockers, tyres etc before i got to worried about more power but each to his own

Alright, I probably didn't come across sarcastic enough, I did try to challenge your logic. But seriously though, if overheating is your main concern, I would say again that addressing the cooling system would be a better solution. All joking aside, think about it, if a bigger exhaust was the solution to overheating, wouldn't the manufacturers put the biggest exhaust system possible and not worry about the radiator or coolant or water pumps, etc...

Nope i think the toyota got sick of there cars and trucks not bracking down enouth so they cursed the 2.4tbd with a to small exhaust so it would brake down more often :D.
But then again you do make a good point.

It does vent alot of excess heat actually. The EGT readings before a big bore and after make a hell of a difference, and help to keep the engine temps down. I swear there have been hundreds of theads on this. 86-surf must have actually used the seach button :wink:

Mate, I used to question these things as well. But if Toyota could save $10 per car by eliminating a component, it would be a big saving for them. Yes the manufacturers try to stay conservative for good numbers on fuel economy, but there are some brilliant highly qualified engineers with billions of dollars behind them working on these things and us shade tree mechanics questioning their wisdom is sometimes not justified.

Now I know for example, the slip yoke design on Wranglers is stupid - but thats only an issue if you lift it!! You don't lift it, its not an issue - a perfectly good design for on-road use.

Save your money and change the exhaust if you have actual overheating problem. Spend the money on more pressing mods, like a good suspension. As far as looking cool or sounding cool, well to me function over form is important (and thats why I drive a Jeep).

yea but 3 inch straight though or twin 3 inch's ?? on a budget wouldn't ya just cut out your mufflers or go a 2.5 straight through?

but well said there are 100 threads on this that im sure people have tested and tried, each to his own.

I am not questioning that, I do trust his ability to search. But going 2.5" twin exhaust or 3" exhaust when 2.5" straight through could work is what I am challenging. I just wanted to challenge his thinking to make sure he is making the best decision that is rational, logical and would work best for his situation. Getting a big bore exhaust for looks is a waste of money, if it adds to the performance - brilliant. I know a free-flowing exhaust helps the engine, but it has to be done within a reasonable range. I changed by cat converter and muffler to a more flowing design is exactly for the same reason, but I stayed with the same bore size because I don't have a turbo - no functional gain.

Have you got some EGT readings before and after a bigger exhaust is fitted?
I haven't changed exhaust size, but my experiments with a range of different turbo sizes shows a very poor correlation of EGT with exhaust flow.

Yes there have been hundreds of threads on this, but I have yet to see one where actual EGT measurements have been quoted. I know people who've blown the head on a 2lT, then fitted a bigger pipe with the new (improved design) head and placed all praise on the exhaust.

A pyrometer (EGT gauge) is a real investment in your engines health. An oversized exhaust isn't.
