Outer Limits 4x4 Board

can you just whack a 3" exhaust on the back of your turbo or do you need to widen the flange at the back of the turbo before you put the exhaust on. i was quoted $700, to widen the back of the turbo flange and a 3" ehaust. is that a good price or keep looking. BTW its for a diesel patrol swb

on 60s it needs to be widened to 3 inch from 2.5/2.25 but can be done simply if you just and paste a little bit. dump pipe to back of car can be 150 for a press bent 3 inch to nearly 2G for a mandrel bent taipan system.

I recently paid $540 for 3" mandrel bent from the dump onwards.

I made my own with some pipe, a mandrel donut, a bit of flexi truck exhaust pipe and a straight through muffler.
All up cost about two hundred bucks and a bit of time on the angle grinder and MIG.
It was a bit tricky fitting a 3" past all the IFS crap under the Lux.
I took to my orig dump pipe with the angle grinder and die grinder and made it 3" right from the flange.

I paid $500 for mine on a 110.

Def90 paid $350 for his on his 90.

So the price should sit somewhere there.

i got a quote for a LWB patrol today for $400 3" mandrel from the 3' dump pipe back,

Hey i'm in Noosa and i'm getting a T4 turbo put onto to TB42 my SWB mav where would be the best place to get a 3" zaust made up? I was thinking just press bend but if mandrel is around a the $400 mark i'll be going that way

i was heading towards noosa exhaust but if there is someone cheaper let me know

Cheers

i went in to Midas at St Marys on saturday morning, and he said $400, that is using weld in mandrel bends and some straight pipe,

i paid $70 for 2x3" 90deg. bends and 2m of 3".

its really not that bad

Love to know where some people get these prices, have not struck one for a 4.2 GU thats under $700 for dump and whole 3inch in Melbourne.

tryed that exhaustfix dude, but he never answered, sounds like hes only interested in sounding technical and wow..

so do you guys recon you need to widen the turbo flange to 3" aswell or not bother with it

"so do you guys recon you need to widen the turbo flange to 3" aswell or not bother with it"

I was wondering this as well!!

Go see Sandy at aus4wd.

I'm sure he'll do it and will be cheaper and at the same time up the boost and fuel for not much more...

I dont know if the dumpipe makes a difference or not, but I made a new one anyway... At the end of the day the whole 3" system DID make a difference.

Mandrel or press-bent??? Got quoted $380 for a press-bent 3" for my 110.

everyone says not to bother with a press bent because its more restrictive, especially on a turbo diesel.

go with the mandrell

if u can afford it do it. less restriction where it counts

ive been in/driven cars with press bent and mandrel..... wow what a shock you cant feel the differance. both landcruiser 2H aftermarket turbos running 12 pound. even the noise was the same. 2.75 inch is still plenty of flow for a 4L turbo.

Thats because 2h's run out of breath after 3000rpm. They could flow that amount of exhaust through a Macca's straw. Just kidding.

If you have got the cash, go for the mandrel system. More scope for improvement down the track.

just had a new 3inch mandrel bend exhaust with dump pipe, fitted to a gu ute for $1250.00. made a big difference, happy man!!!! i thought that was a reasonable price, but sounds like some of you have been quoted alot less

Only tightasses get press bent.

when your working it out I reckon press bent on a 4b wouldnt make shit difference, its not a performance rig... but does in price
