Aftermarket exhaust SDV6

[Owen]

Has anyone had experience fitting and aftermarket exhaust to their 3.0? Mine is a MY11 and the existing system has dropped its guts, sounds like a bunch of tin cans rattling around !

I have seen the Legendex system at $2700 , seems expensive but i suppose they would not sell that many. I am in Melbourne.

Thoughts, suggestions?

See an exhaust shop and have them build something.

Will likely be a better alternative and often cheaper.

A few mandrel bends, a new higher flow box in the guts...

or no box in the guts , nice note , not loud

Went to an exhaust shop, $1500 replace main muffler back, no resonators, in Stainless.
Britpart unit including responators, in stainless, $1036 delivered.
Legendex system from genie, $2699
Legendex system from Roo systems, $2500

Do you know what’s broken on your existing exhaust?

Yes, the weld / crimps have let go next to the spare tyre. I have fixed it with the MIG but is a great opportunity for an upgrade 😉

Hi, my D3 exhaust had been bent over time so had it replaced by a local exhaust guy before xmas, $350 without the resonators fitted and he increased the dia slightly as it allowed for a thicker wall thickness. Did a great job and sounds about the same.

[LRD414]

I would have assumed no resonators would be noisy.

I assumed the same and left the resonators on

Your earlier photo looked like they were getting replaced with just pipe?

[discorevy]

yes , I made and tacked the centre pipe up with the intention of getting a local exhaust shop to make 6 of them using mine as a template, they wouldn't do it as they wanted the cars there [tonguewink], which wouldn't work logistically while they were on my hoist, ( I would think it shouldn't be that hard as the centre lines are the same ) so I just got them to bend up the resonator pipes , I then came back , welded up my prototype ,painted and fitted it and found the note to be great , left it at that

[Tombie]

I’ve still got the rear cans...
They and the rearward pipes weren’t damaged on mine at the time

The exhaust guy told me that he had left resonators off of a number of turbo diesel vehicles and had little impact on sound levels. I decided to have him leave them off but hold on to them just in case! As it worked out didn't need them. My D3 seems to breath a little better but that may be compared to the old squashed pipes[bigsad].
From what I have read the D3 exhaust system already breaths pretty well.
If I could work out how to insert photos of the new system I would[bawl]

[discorevy]

I'd think if yours sounds about the same , that your main muffler and cat are still in place , there wouldn't be much restriction in the resonators because there are two of them and by the time the exhaust gases have got that far they have cooled significantly .

Yes the replacement starts from the back of the center muffler with twin pipes.

If we could get 30 sets a local guy would make them .

I've also looked at the Roo Systems Legendex SS system. They use a 409 SS and full mandrel bends. Price seems a bit high, 2.5K and you have to DIY. Ive just had the tow and economy ECU tune done by them, seems to work well, apparently works better with their exhaust fitted too....

I would definitely go SS, but you need to know what grade of stainless they are using. So far no issues with the factory set up, would love to have bit more noise though...

The Britpart is 201 Stainless. The properties of 201 are a little better than 409 however they cant tell me the wall thickness to compare apples with apples.

I have been rethinking the stainless though re off road, I do have a few dings in the existing system from off road, maybe the pipes will get banged up before they rust, hence just go with steel.

[Eric SDV6SE]

Owen,

Someone at my current work recently upgraded their exhaust (larger dia. etc for better flow), and they were told to go with mild steel to avoid cracking, especially for off road use. My personal preference would be SS, just need to select the correct grade. I would also assume (rightly or wrongly) that companies like Roo Systems or Britpart would not offer SS systems without some significant R&D, as they have reputations at stake.

Due to EURO Emission standards compliance requirements, the factory cannot fit these high end free flowing systems as they have to cater for the entire range of driving styles and conditions, so its a compromise.

Also, if a full SS system (whatever grade) lasts the life of the vehicle, then i think its a good investment. I would hate to skimp on an exchaust, say pay 1200 for a mild steel system, then have to replace it again, (effectively spending 2400) when you pay 2500 for the same system in SS once.

Personally, I am saving for a SS free flow system, hope to get it at the end of 2018

Just my honest thoughts

Regards,

Eric

to me, that sounds atrocious. like a hilux with open pipes.. would drone hard on the highway too. does anyone have a 3lt with exhaust done they can make a video of please?
