I did it to mine.....


It made it noisier, and the turbo sounded very cool.



I've since put the muffler back in again.

Why did you put it back in?

Because he is soft!!! And probably got pinged for being to noisy

How much more noisy was it with the middle muffler off? I don't really care as long as it doesn't drone at cruise. Any performance gains to be had or just a cool turbo noise?? The TD5 has a pretty decent stock exhaust apart from that massive front muffler.

So worth it just for the cool turbo noise

I replaced mine with a big straight through one (still with offset outlet) as I was trying to find the source of a drone and the muffler seemed to be hollow. I didn't notice any extra noise but the turbo response improved. I subsequently replaced the bellows-type flex joint (saw that it had a 50% restriction, so a bonus) with a wire one and that got rid of the drone and further improved the turbo response.

I pulled mine out before I left hervey Bay last week, to be honest its barley any louder. If at all.:confused:
Pulling a trailer and the engine working in the hills it's has a bit of growl but nothing like my 550hp cat dragging 65tonne.:)
Same with the turbo, it's barley noticable.
Question, who has pulled the cat out?
This might be keeping things quiet on mine.

The turbo smooths the pulses of the individual cylinders.

My old 903 V8 Cummins (no turbo) has just had the injector pump overhauled and doesn't it make a good crackle around 1500 rpm with a bit of throttle and a full load.

We use too, alooooong time ago, put about 5 litres of petrol to 500 litres of diesel in the the 903 vt's
Then take off to Sydney, a nice blue flame out the stacks at around $1.30 @ 2100 rpm.:wasntme:

Why did you put it back in?

Just to quieten it down. It'd been running on Simex and muds just about exclusively and I'd just decided it needed to be quietened down for the amount of open road driving that I do. I stuck a set of Pirelli ATR's on it which are very very quiet, but it was a bit of a wasted effort considering the exhaust - so I changed that back also. I now need to just pull the TD5 and that should make it quiet enough. :D

No pings, it was louder but not that loud. The turbo spooling is very cool though.

well I removed my massive front muffler on tuesday and had it replaced with a piece of pipe for a measly $40. the $ to :) result is pretty high. Turbo spool is definately alot earlier, there's a nice roar when giving it guts through the sand. The turbo is also a fair bit louder, especially if you have a snorkel.

The noise from the snorkel is something I've noticed again on mine, having got used to the original noise when the snorkel was fitted.

Where did you get the pipe, just from an exhaust place?, because thats pretty cheap.

mine was about 40 bucks too,,



interesting thought about cutting out the cats----

Interesting, everybody has noticed the turbo making more noise.
Like posted earlier, it has made bugger all difference in the noise stakes on mine and I can not even hear my turbo spooling up.:mad:
Are you guys running exhaust cats??????????

Paid $40 to get mine done i still have the cats, and even at idle you can hear the slight whistle and when it spools you can hear it very clearly! :D

Read this with interest but don't know if the mind is playing tricks though:bangin:

Is it right the the std flex joint on the early D2 TD5s has an internal pipe narrower that the exhausts 2.5 inch diameter???:(

If so if you were looking at removing the cat to increase the exhaust volume flow to change the flex joint as well?

Cheers....

No, the earlier TD5s flex joint is better than the later flex joint, the system is 2.5 all the way from the turbo to the end pipe, if your worried about noise, just replace the centre muffler with a straight through hotdog style muffler, I know of guys that have replaced the straight pipe that they replaced the standard muffler, with a lighter more straight through muffler, Vortex mufflers are one that is used.

So Baz,

Whats the go with suggesting putting a 'hotdog' (hold the onion):angel: in rather that a straight through????

I did many of my V8's, I 1st pull the centre muffler out but soon realise that they sound like lazy ski boats out of water.
If you really want good sound, go the full hog, custom extractors mandrel bend if you can source it and than a full Remus exhaust.
They are tuned and slightly muffled, sound absolutely magnificient.
Nothing like a remus as far as I am concerned and most who have them around the world.
My mate even has one on his X5 diesel. Made that go better too.

Well for one it makes the car legal and 2, it is still straight through but a lot quieter, than just a straight bit of pipe;)

Discowhite, Tombie2 and me are doing it this way, along with a few others:D

Search Vortex, there should be a few post on the subject.
