JMM exhaust tone

[Syk0AU1]

im considering gettin the dev1 from JMM very soon, but wonder what it will sound like. Does anyone have a wav file or mpg that shows what the au's sound like after the dev1?

Sorry I've got no mpeg/wav file with of the sound of mine but it sounds awesome!! I wouldn't trade my exhaust note for anything in the world. Mine has a real nice 'sports' note to it.

Also, going by the last time I heard Casper's car, my note is quite different to his. Mine has a much deeper rumble to it.

[Syk0AU1]

im too after a nice deep rumble, a nice tone abit deeper than caspers. Do i have to say anything in order to get it, by the way they install it, or is it because casper has an xr6 or what?

Yeah just ask Brenden when he does it. When I picked mine up it was already done with a sporty tone and was told if it was too loud to take it back within a week but I liked it the way it was :hihi:

where did you get it done krissy?
you from melb?

[The Mighty Red]

I'd say the deeper rumble is because it doesn't have a resonator at the back of the exhaust.

At JMM
Yes, from Melb (Werribee)

Krissy, are you running JMM Race Headers too, or the Scavenger/Streetfighter Headers?

Cheers

Sorry guys but having mostly V8's in my life the 6's still don't cut it with exhaust sound. The only decent sounding 6's I've heard were the old log manifold ford 6's of the XK-XB's with the split system.

But the deep throaty sounds that I've mainly heard on the ohc ford 6's either have a hotdog or no rear muffler & the standed redback or Lukey centre muffler.

Mines not deep and rumbly, its more raspy and gets a real snarl to it at high revs. I think it may be partly due to the VCT engine as most others with the same setup as mine have a deeper rumble.
Still, the WAV doesnt do it justice, its got a real bite to it in real life without attracting the undue attention of revenue collectors.

[buickman]

Well my ford stock rear muffler is being replaced tomorrow as it has got a hole in it. I think I will go the hotdog this time ,I've got used to some noise now . The pacies & redback centre muffler is Ok.

I now the 4480 are 3 into 1 & the 4499 are 2 into1 are JMM 2 or 3 into 1.
Also are there any difference in overall lengths of these extractors where they bolt to the cat.

cheers buickman

where would u guys reccomend in QLD to get a good set of extractors and exhaust through??
im thinkin just my local exhaust shop but get some GOOD extractors fitted from the likes of genie or somthing.. as well we dont have JMM in sunny QLD sadly..

that's exactly how i'd describe the tone of mine. its not very loud but whips up the decibels at high revs. i probably would've liked more sound but then i remember that sound doesnt equal power - i've dropped plenty of loud cat backs that end up showing nothing of substance under the bonnet.

its also got a rough gurgle at idle that sounds pretty mean i'd say...moves a hundred or two revs from 1000 :

then again its a dev 3 with streetfighter headers so a plain dev1 would sound way different i'm supposing

will try to get a sound bite of it when i can be bothered

You wont beat Men at work exhaust in capalaba Pacies 4480 $500 fitted. Mandrel bend with muffler & Resonater $280. My EF has a 2.5 with no resonator (too Loud) screw the noise but was $200 fitted including a nice chrome exhaust tip. They are honest too!

[blackers10]

are those pacemakers good for the VCT 6 in my fairlane? coz i read thru here they need to be GOOD to have any point in attaching them!

ill havta get a quote from the local joints see what they can muster up..my lil bro is starting a new job at a mechanics next week so should get trade rate aye??

cheers fellas

If you live on the Northside of Brisbane you could try Rob Bliss Exhausts at Geebung or Ultimate Performance Exhausts at Brendale. Both do great jobs. Had my AU XR8 done at Rob Bliss, very happy with the result and after service is terrific.

[blackers10]

yeah im on the north side.. at morayfield

Hi everyone,

I finally got around to recording my Fairlane exhaust note. It has a JMM DEV 3 VCT kit with race series headers. Here is a link to the MP3 file (488Kb):

"Acchh! Sounds like that gopher I caught in the lawn mower!"

[Casper]

Geez Dauphin... redline the puppy!!! I doubt it went over 4000rpm the whole time!

[sfr rob]

oh.. sounds nice when ya take ya foot off the throttle!

how much does a dev3 kit set ya back?
is it worth it?

Rob :eclipsee_

[Walkinshaw]

Sounds similar to mine. JMM use redback systems + their own headders.

And i agree with casper, sounds a little soft on the RPM side of things.

[Dauphin]

You're right, Casper. Hehe, it was a frosty day and a cold engine. I thought about doing it again to redline but oh well.

Rob, it's definately worth it. Each time I had something done the machine felt more alive, especially when the chip went in. If you go to the JMM website (www.jimmockmotorsport.com) you'll see the prices for DEV kits. I don't know if VCT makes a difference in sound, maybe Casper can answer that.

I plan to mount the camera at the towbar one day and do some sprints, see how that sounds.

Actually, off topic. I mounted the camera on my passenger side sunvisor and went for a ten minute drive to someone's house last week. I caught four stupid acts in that space of time - two of them were people pulling out in front of me without looking. (None of them P platers and both in Holdens.)

Hi Andrew

Bit off topic here.... but....

Ive been having fun with my fairlaine at JMM as well, headers, exhaust, stall, intake, putah and shift kit.

Damm Im impressed with her now, completely different car.

Ran it down 1/4 on Sat with HD towbar kit and roof racks on 15.6 with 60f 2.160

Have you raced yours yet?

[Dauphin]

Not yet - I don't have enough courage to race it.

The VCT's seem to have a more raspy sound rather than the deeper growl of the Intech. Oddly enough yours is certainly deeper sounding than mine (so is Laminges) however I would assume that being LWB the extra pipe length may have something to do with that.
I would also assume that the placement of the cat and muffler... along with muffler types... may have some influence on the final note.

[GT290]

: : : : Has any one just used the standard system on their GT and just either taken out the resinator or and titted hotdogs. If so what was the sound like then. I too am looking at trying somthing with out too much mods. I have fitted the CAI and that made a huge difference to performance and sound when you give it stick...but I miss that nice rumble you get.

[JC]

Rear resonators removed on a BA XR8 sounds good - should be the same for a GT.

[GT290]

Thanks for that, One thing...did you get any droning inside?

Cheers
