Thread: Aftermarket exhaust available for Disco 3?

What exactly did you hope to gain from fitting a "Aftermarket " exhaust ? Obviously you have the V6 petrol engine ?

Disco3_BigBoat,

I can not help you.

However I was driving along today looking at the rear of a D3 in front of me and noticing how the twin pipes (TDV6) seem to be the lowest point at the rear of the car and began thinking surely someone must have thought about, planned or already done a mod and found a new route for the exhaust so they either go over the rear axle or exit in front of the rear wheels or something like that.

I assume you are talking bigger pipes for better performance etc but if with your chipped and lifted D3 you were planning to get really serious and an exhaust upgrade was wanted then a change in the rear design would want to be considered.

Will be interested to see what transpires.

If you have no luck here, go on the Disco3UK site as there is probably a greater chance you will find someone on there who can assist.

just go to eny well none exhuast shop,,, they will make enything you want for i guess half the price of a pre made pipes,

Alive tuning do a TDV6 system with removable rear section for offroading.

I was told a little while ago that there was alot of work went into the design of the Disco's air intake & exhaust sytem, and there is not much room for improvement.
I'm leaving mine as is.

The D3/4 being such a quiet vehicle, I think any exhaust mod would run the risk of introducing unwelcome noise, such as a drone. IMO it would be prudent to explore this option more thoroughly before laying out any cash.

If it is just a performance gain you are after, I have a feeling the gains will be minimal. We are not talking about a 4.2 Patrol diesel here. GGHAGGIS ran a D3 in competition. If there was anything to be gained, I would guess Gordon has tried it already.

Admiral is right. Gordon would be a good person to get advice from as far as extra performance.
The money that you would have to spend on a custom exhaust, would not be worth the minimal gain. I had an ECU upgrade done on my D3 (and nothing else) and the power / torque gain was very noticible.
Your thoughts Gordon???????????

Cheers, Craig

Most of the comp work I did in the D3 didn't rely on tiny incremental performance increases, which I suspect is all you'd get from a custom exhaust system. Upgrading the intercooler will give you far greater increases (have a look at AliSport in the UK - of course, this only applies to a diesel D3!).

I did chat to one of the guys working on a D3 in Europe (for the Dakar Rally, but they never ended up competing), and they had removed the two rear mufflers (replaced with a straight-through). They claimed a minimal increase (they had also upgraded the intercooler), but had heard of concerns about the back-pressure on the turbo. I don't think you'd get any greater increase with the petrol V6 + exhaust upgrade.

In terms of clearance, one of my clients has replaced the twin pipe design with a single pipe (exiting on the driver's side rear). He still had the pipe routed under the rear diff/driveshaft housing, so didn't really gain much in terms of clearance. With the adjustable suspension it isn't really possible to re-route over the top, but it may be possible in a coiler.

Cheers,

Gordon
