Outer Limits 4x4 Board

Yeah, better sound, more throatie

Est price - $650-900. Mandrel, thats the key

so a 2.5" Mandrel bent off the dump pipe with no muffler, is what i should be looking into ?

if this is too much $$$ is there another way but cheaper ??

Whats ur price mate? If your budget is low then i would be seriously considering quality.

I got a custom made exhaust with no flanges, ended up rattling to bits...

2.5 or 3.0inch is the way, i would go a 2.5 but others think differently.. much of a muchness

it seems you have a few posts on here seeeking advice on mods.. I would be getting the exhaust 1st then moving on to suspension and lift etc etc.

A really restricted exhaust will, in turn, shorten the life of a turbo charged engine. Turbos have alot higher engine gas temps, so the last thing you want the hot gas to do is bank up around your engine and turbo, you want to be getting it out as fast as possible... a free flowing exhaust will lower your egt's up to 125-150 degreees..

well not really sure what my price is because i am looking at getting a suspension lift (round $1500), and than later down the track some wheels and tyres (least $2000) and other acessories later on aswell (snorkel etc).

But at the end of the day i dont want to get something that i need to relpace or fix only couple of months later, i will pay extra for guality!!

yes not really sure what i will do first, thats my next decision after i choose what i am actually doing....

So saying about the engine degrees temp the exhaust system you mentioned before would be the way to go?
.... 2.5"/3" mandrel bend, no muffler ....

yes having no muffler will give you better sound, turbo cars always run quiter than non-turbo counterparts, and i think you'd probably be best off with a 2.5" Mandrel bent exhaust with a flex pipe at the front and no mufflers, u'll get better power and sound and should only cost around 800-900 dollars. and in the end you get wot you pay for so theres really no cheapskate way to have a brand new awesome setup, but for something thats half descent and value for money the system i said should suit you to a tee. i also think that a 3" is probably a bit big for a four banger, i think old mate is just over compinsationg for sumthin and trynna look like he's got a big rig.

when you say better power, is that going to be very noticable? or does it only give you a slight power increase....

Dont forget the 1KD runs a Catalytic converter too, and you'll need to factor in a high flow cat into the exhaust costs.

sorry mate but what the 'F' are you going on about?
i didnt understand any of that haha, put it in new to the 4x4/mechanical area language....

2.5" should be ok for Mandrel bent and 3" for Press bent.
As Feass says, the quicker you can get the exhaust gas moving the better, but if the pipe is too big it cools quicker and because slower to exit the system

okay than, cool!!

So whats the difference between mandrel bent and press bent??
Can someone discribe so i understand??....

the top bend is mandrel, the bottom is press bent, ill let you decide whats better

by the look of the picture i am guessing 'mandrel' is the best....

That right????

I dont want to do anything to big or money wise though....

any other ideas to help me out?

None of these mods will cure "slugish off the mark" (turbo lag). but they will help. 2 1/2 exhaust is plenty big enough for a 3litre, however the hilux all ready has a good size exhaust from factory. My advice is lose the stardard muffler and fit a unbaffled resinator. You may gain 5-10% improvment in preformance. But the best gain will be from a chip, up to 20%, not a DP chip. If you want some 1 on 1 advice pm me.

so in other words there isnt really a cheap alternative for a new system.
You got to be ready to pay atleast round $700.....

got a new exhaust installed the other day and extremely happy!

all the did was cut it off before the muffler (so i dont have one) and weld on a stainless steel 2.5" exhuast for ONLY $120....

Straight off i can tell it does give you a slight change in performance due to being less restrictive and letting the turbo work beta. It also gives it a better deeper sound.

Good to hear ur happy with an inexpensive mod that works.

yea mate, thanks so much for the work and such a awesome price! real happy and would recomend to anyone....

with that cylinder thing that was before the muffler (sorry cant remember its name). Do you know what i am talking about? lol....

But is it possible to take that off? If so what effects does it have?

thats the cat converter, its got to stay, the fine is huge.

okay than fare enough!

but just to say if it were to get taken off, what effects does it have?? as in sound etc...
