I know there's a v8 in there somewhere - just can't hear it!

[ariddell]

Guys,
What's the concensus on exhaust options to free up a bit more of the v8 grumble on a d2?

I know how fantastic the Rover V8 can sound from the symphonic aural assault the TVR gives with an engine not overly far removed from the Thor, but the d2 noise just isn't doing it for me at present. Sounds like it has been silenced within an inch of its life to avoid upsetting the kids on the school run with only the barest hint of burble.

I'm not looking to turn it into a hoon mobile with a bean tin hanging off the back or anything, just a firm believer that a V8 should properly sound like a V8!

So, what have other people done and how has it panned out? I did a search and there seem to be quite a few threads about exhaust options for the TD5 but not much on the v8.

Thinking it'll probably be pretty high on the list of mods for when i get it through the VIV inspection hopefully next week.

Thanks

Al

There is a small snippet of info in this thread:

Dunno if that will help ya... :)

[dirtdawg]

extractors and a good 2 and a half inch single system will sound pretty good, its what i have

do they increase performance as well?
yeh mine seems to have more of an electronic whine :P

[V8Landy]

i put 2.5" pipe from the twin pipes back through a sports muffler in the middle on my 3.9.If i was doing much towing i would put a resonater on the back if you did this you will get good sound but not to loud.I am guessing that yours is a 4ltr so should be around the same i would say:D

I am taking the plunge after thinking about doing this for ages.

I am doing the el cheapo option which is to replace the centre muffler with a less restrictive glass pack sports muffler. Rest of the system is standard.

Went to an exhaust shop in Croydon NSW used by a forum member here a couple years ago, but I couldn't find the thread to find out exactly what muffler he used.

My goal is better sound without a drone and the hope of slightly better performance and economy (but prob not).

I have reservations about replacing a perfectly good stainless muffler but I guess you only live once and this will probably be my last V8. May as well enjoy the sound.

The replacement muffler costs $240, will let you know tomorrow how it went.

You won't regret it:twisted::twisted::twisted:

In my last RR I had a rip snorter of an exhaust - sounded great.

Problem was I drove it to the tune of the exhaust - always kept it on the loud peddle way too long.

Current disco has extractors, a 2.5 inch system and resonator on the back. Not sure what type of muffler is in the middle.

It does make some noise, not as much as before, but my wife and neigbours are much happier for the experience.

[Lotz-A-Landies]

There is nothing that sounds as good as a V8 (except maybe a Merlin V12), so it should be heard, but only 1 suburb away! :twisted:

I'd go the extractors and the 2 1/2" stainless system, at least that's what I have, but is still just a little too loud.

[p38arover]

Yeah, I know what you mean. My P38A doesn't sound nearly as good as my previous RR with a 3" exahust system.

[ariddell]

Thanks guys.

Well i got a bit of a suprise today (becoming par for the course with this car it seems) when i had it checked over for the rwc. Turns out it has "non-standard extractors and cats" fitted at the moment which would apparently need to be fully checked out to ensure they comply.

Not quite sure why the previous owner would have had extractors etc done without replacing the rear muffler too. Just hope they are allowable for the rwc as it turns out there are a good few other things i need to sort out too, so could do without having to replace these back to standard.

Still on the plus side it means i should get the maximum benefit from a 2.5/3" cat back system when i get it through the rwc.

Keep an eye or should I say ear out for my silver D1 around sth melb / albert park if you want to hear how good a disco can sound. You might have seen or heard it already. :twisted:

Nice, that sounds the business - how is it on the freeway etc, much drone or is it quiet unless you blat it?

What sort of system is that?

[4X4V8]

Just got my D2 manual back from getting an X-Force High Performance centre muffler fitted.

First impressions - it gives a deeper, louder note at idle - sounds really good- and maybe it's just my imagination (probably) but take-off seems more crisp - it doesn't seem to bog down as it used to.

As you rev it there is a slight booming under load at abt 2200rpm, not intrusive though.

When you rev it doesn't sound that noisier than standard from the driver's seat.

I asked about free-flowing cats and extractors, there are a few manufacturers for the extractors (Genie and others I can't remember) and cats are about $300 a side. The bloke at the exhaust shop said that the exhaust back from the muffler really did not need to be changed - it's mandrel bent stainless which he thought was pretty good as it was. He suggested just extractors and free-flow cats.

He also showed me the gas leaking from the seam of the std muffler. He said it wasn't too bad but indicated it was beginning to deteriorate. I now have a reason for replacing it if the Minister of Finance calls for an enquiry...

I am going to get a recording from the back of the car while taking off (I think you get a better idea of the sound it makes under load, not just revving at idle) once I can figure out how to attach my camera to the back without it falling off (!)

Sounds probably like the same thing the previous owner of mine went for, extractors and cats but nothing further back.

Will likely drop into a place i know nearby who are happy to do some custom building/swapping of components to get to a noise level I am happy with when i get it through the rwc rather than trying to get an off the shelf system.

2.5" pipe from y-pipe back, magnaflow centre, small hotdog resonator at the back. If I ever get the engine warmed over or replaced I'll put in extractors too.

Its loud outside or with the windows down. SWMBO was complaining about the noise so I lined the rear door, rear floor and walls with dynamat. This was a big improvement. You know you are driving a V8 but its not intrusive until you give it a boot full. Under load at 3k rpm it sounds :twisted::twisted::twisted:.

Its given me a little more torque and it tends to rev more freely. It will pull up long hills in low 3 that would have been low 2 with the old stock system.

[4X4V8]

You won't regret it:twisted::twisted::twisted:

V8Landy, you were so right. This has transformed the car. Have taken it for a few drives now and it is bloody awsome. Just sounds perfect.

If I was going to be really picky, you do notice a slight booming in 5th on 100km/h, but that's it. More than worth living with, for such a great sound.

[tempestv8]

The catalytic converters really kill the "pulse" of the V8 on the DII, which is why it will never sound as good as a "cat less" DI V8.

I've gone through the full cycle. First I removed the rear resonator and replaced the center muffler with a Magnaflo (straight thru). Sounded very bad ass but the drone was unbearable.

Then I refitted the factory resonator and lived like that for 3 years. I finally couldn't handle all that noise and refitted the original middle muffler, and she's quiet again. Yippie!

The Land Rover exhaust system is pretty good and I've not experienced any fuel economy gains for the extra noise that the Magnaflow created.

If you want a good V8 sound but no drone fit a Flowmaster centre muffler as I have on my 3.9 RRC.
MOTOSPECS automotive aftermarket products - incl brakes, suspension, transmission & electrical (http://www.motospecs.com.au/flowmaster.php)

A Flowmaster gives a nice "mouse" beat at low revs but no drone.
It is a lightly baffled muffler .
I also have a dogleg oval straight through resonator on the back, as SWMBO objected to the hotdog.

My D1 V8 has standard manifolds with a 2.5in system with a muffler and resonator. Don't know details as they were fitted before I got the car.

The office I am working in now says it vibrates the windows (3rd floor) when I start it and idle out of the carpark :D
However it is quiet as a mouse compared to a RRC in our club. I don't know what his setup is.

Mine doesn't drone but it can be annoying to have it idling while standing behind it talking etc

[PhilipA]

Funny, even though mine is quiet especially in the car, it rattles my garage windows, and I have noticed it can set off car alarms in shopping centre carparks.LOL
Regards Philip A

[100I]

:D Our V8 used to rattle the old & dried caulked windows in our old house.
It was an easy telltale that SWMBO was home.
It had the centre muffler replace when the baffles collapsed in the OE muffler, it was of similar design to OE but was smaller and gave it a crispy 'chev' note but I'm sorry I don't remember the brand.

[kitacooch]

i am about to remove the rear muffler in attempt to get better note, also have a luky centre muffler to try, heard it sounds great, will have to wait and see

[4X4V8]

Will try to figure out a Youtube recording of my D2 with sports centre muffler today. Prob won't have time to get a driving shot now.

My set-up is really not that loud - my wife drove off yesterday and while the deep rumble at start-up/idle was obvious inside the house, it wasn't that noisy as she drove off down the street. I'd equate it with a HSV or FPV level of noise - more a bass tone at idle than loud thru the rev range. Still pops on overrun, though. Nice. Good for old farts like me who can't do the full V8 noise anymore but can't stand having a V8 that sounds like a vacuum cleaner.

I reckon a std P38 sounds pretty good, my D2 is only slightly more noisy than one of those.

Anyway, still highly recommend the centre muffler change in a D2 V8.

[mrapocalypse]

I chopped the rear silencer off... YAWN..... Nothin just a slightly uglier and pointless growl. The I got a muffler that I asked to be "A Burble" which it is. Has a nice soft rumble that you can't hear at higher revs but is kind of fun at about 2000 rpm. Keeps me off the pedal. It's a work in progress. I am trying to drown out the ACE pump!

Got it done at a performance shop in Woolloongabba! $275 and they are top people.

[Boxer]

I went for a 2.5 single press bent system with a muffler and resonator. Sounds great and for the mean time while the cast manifold are holding in the gasses, I'll stick with them. I figured I wanted to have it sounding better, but not go too extravagant as there's a good chance it'll get a little bit beat up off road.

[BustRucket]

Got an exhaust put on mine on Thursday. 2.5 inch from the Y back. 1 straight through muffler and no rear resonator. I can barely hear it at 110 on the freeway, but it barks under load. Just the way I like it.

[ozscott]

I had a very good bloke who specialises in custom jobs do my wifes 95 D1 3.9 auto. He said he would go for a mild system that made it sound better but not loud. 3 inch system with straight throughs....arrhh....started it and new something was crazy. Drove it and it sounded like 6 litres and angry...he couldnt understand it. He said later that it was probably the sound emitted from the alloy motor. He couldnt believe how fat it was !

My wife would drive past road workers and they would be looking to see where the sound was coming from! Needless to say that apart from taking me back to 17 it was just too loud. He stuck in a relatively good flow glass packed muffler and still had to stick in a better resonater than the one he originally stuck on. Now its got a nice quiet burble and is very quiet inside - quieter than original but goes well thanks to the 3 inch pipes.

Cheers

[Fleabag]

All I wanted was a demure burble from my V8 D1, which I wasn't getting from the standard muffler. I didn't want resonance or to break windows.

I just had the centre muffler replaced with a tri-flow and now it is perfect.

[ariddell]

Got mine done at the weekend, went for a 2.5" system and stuck with 2 mufflers but both straight through.

Now makes a nice deep rumble especially at low rpm but isn't too intrusive on the freeway.

Might remove the rear one at some point in the future depending on how it beds in.

Got my RR P38 done recently, i'll put up a seperate post with the details. I'm pretty happy with it - quiet when cruising, loud when moving :twisted::twisted::twisted:
