Mate you are doing a great job here ,keep the good work, but you almost need your own sub section or own section all together ie on the main page where the differant model are....

maybe even have a sub menu where we can post questions to suit a certain make of truck...ie Rover , Toyota, Nissan etc so its much easyer to aply info to our own models.

Just think it would be easyer to follow if we clean it all up a little....if it not to much of a headake or prob for the modurators etc

I know you can seach a section for tips on your model but doesnt always get all posts etc...

Just an Idea...waiting to get shoot down

mabye the moderators will read this and make a section for this topic
my phone number is on all my replies just maybe they might ring me to set that up
lol

hey amshaw
the moderator did reply and your sugestion was good but the way the forum is set up does not allow for the changes

I have a 2000 3.0TDi auto wagon.

I am about to put a performance exhaust on and I would like to know what you recommend.

Thinking of 3" pipes, 3" straight through GENIE muffler and Hi-flow CAT.

Would you go Hi-flow CAT or no CAT at all??

Would you put on a Hi-flow resonator??

Any assistance would be great.

hi there

you could go to a 3' system with a straight through muffler
as far as hi flow cats are concerned it is all a bit of a falacy
it is a bit like a larger piece of pipe
there is no difference in a ceramic brick inside the cat as there are only about 5 manafactures of the catalyce material in the world. and they are all made the same
the only difference is that you could possiably find a cat withh a much larger body which would give you more area to flow through

my sugestion for a cat woul be to go to a new large s/steel core cat these flow about 20% better than the older ceramic ones

having a resenator is up to you depends how loud you want it
but i dont think you will need one

try using a magnaflow muffler instead of a genie they are much stronger and better packed

ross

Thanks in advance.

what is the best exit point side straight out rear etc
what shape tip (curved down out etc)

i have a swb patrol TB42 with extractors and a 2.5in exhaust. the muffler baffles are nearly destroyed and i was contemplating putting a straight through ppe replacement (no muffler). im not worried about the noise but is there any problems in engine power and/or fuel consumption??

cheers

GQGasPig wrote:Hi Mr EXHAUSTFIX,

I like your work on the forum.

I have 91 LWB GQ wagon running gas/LPG with what I believe is standard exhaust, there is no cat and the muffler is riddled with small rust holes but does not appear to be leaking yet and the pipe has a fair bit of corrorsion.

I recently put 33x12.5x15's on and lost some fuel economy (what's that on a GQ anyway!!) and power.

Given my exhaust is on the way out. What would be the best set up (are extractors worth it and what size pipe and muffler should I fit) to regain some economy and power without driving myself nuts with noise?

Cheers

I have a HZJ 75 cruiser with a naturally aspirated 1HZ. I would like to rearrange my exhaust to make space for some other things under the tray. Whilst I'm at it I would like to go the extractors and an exhaust upgrade. Someone else has already asked about this engine I know, the difference being, I would like the power and economy increases with the quietest exhaust noise possible whilst not defeating the purpose. Could you please include some specific brands and models of muffler in your reply. Thanks very much.

BOGAN wrote:Hey Ross i know this is not 4wd related but thought i would still ask it
Have posted same ???? on Just Commodores

Looking at doing a exhaust system for the VX SS Commodore and was wondering what you recommend was thinking extractors/headers and then a 3 inch all the way through with hi flow cats are there any systems you can recommend as a complete front to back been looking at a few but there are so many that claim they are the best


Any help would be great

Cheers Dave

BOGAN wrote:have been told that using 3 inch is not always good and that 2.5 will be sufficient for power and sound wise

Is there really anything wrond with using 3 inch like i wont lose to much back pressure

Its hard to find someone who will give a honest no BS answer around town

Vehicle 80 series
Engine 4.5 Petrol

Recently modified the exhaust to make it run down the inside of the chassis rail.
Current sytem goes like this.
extracters, 2.5 inch through to standard muffler (ie. first mufler removed)then standard pipe finishing just past back wheel. (ie. final muffler removed).

Sounds rather tinny.
After a deeper sound but not real noisy with extra power.
What should I do.
Thanks in advance.

Have a 83 lux with VN series 2 T700 auto, what would be the best set up for torque / power without having a drone.
Was recommended pace maker headers 2.5" pipe and tri-flow muffler in a single system.
Is a cat converter really needed? [ except for rwc ]

cheers

you could go up to 2.5" with this and use a larg straight through truck muffler in the front (m24250) and a good resonator in the rear(bm444)

this will give you max power and sound

expect to pay about $400 with extractor fitting

hi there as far as moving exhaust u might have trouble keeping it quite enough
because you need to run a special muffler in the front to reduce enough noise
i make this muffler and it has been designed for this very purpose but it will only fit in the original spot

Is the special muffler in the front the one that is behind the front wheel? If so I can fit that no worries, can you give me a price with freight to Townsville please. What muffler should I use at the rear? I can fit anything that needs to go in there, just need to know what the components are.

Thanks.

thanks for that, im assuming the resonator is the small muffler looking thing at the rear? is it nessacary to have a resonator and what exactly does it do? can it be removed all together or moved forward. the reason i ask is where it is at the moment its vulnerable to damage when dropping off big rocks
