VCT Exhaust

Bucknaked · 17-01-2005, 07:05 PM

Well I'm booked in on Wednesday for some back end work on my exhaust. Something about CAT back and new resonator and stuff like that. 2.5 inch pipe. Excuse my ignorance, but I know squat about these things. I'm after a better note, plus I think my rear muffler has a hole in it. Pipes out the right, noice out the left.

Anyway, I was wondering whether they are many benefits for the VCT doing these couple of things. Does it help the VCT to breath a little better. City Custom are doing the work and they do top stuff for the 8's and I hope their work is as good on the 6. Anyway, I hope she will sound better and go better.

It will make some difference to performance and a better note but dont expect miracles. The VCT had a twin exhast system setup as stock that was very capable. Its main problem was the exhaust header.....which is just like all the I6 headers...basically crap.

Still, will improve a little in performance and a lot in sound. Just make sure you get the resonator at the rear or it will drone like crap.

Bucknaked · 17-01-2005, 07:26 PM

Cool. He's pretty good in what he does.

Eventually I'll do the header, but for now, a sound is what I'm after

genebaby · 17-01-2005, 07:44 PM

How much is this sound going to cost? I hope it's worth it....

I got sound for free before I did my exhaust, the headers cracked :P now that turned heads rofl

I'm gonna beat you around the head with the part they remove. :gren: :evil_laug

Its certainly not 1300 and theres nothing to edit.

Its going to improve the airflow of the engine thingy magiggy.

Anyway, what you doing browsing the secret AU thread. Are you a closet AU fan?

I hope you've seen the before and after dyno graphs....

When I had my Sandman Panel Van, we used to go to the Nats and disconnect the pipes from the bottom of the headers. Nothing sounds better than a V8 with no mufflers.

I have the before graphs. And I'm using Caspers after graphs.

Its all about looks and sound. Nothing to edit.

Yes it is. You are editing the exhaust you used to have out of your car, and putting in a different one.

Its a 6. You do the little things, to make it a little less boring to drive.

Or you do the bigger things...and beat most V8's

Its in the shop getting an exhaust mod too. New Carboard and some stronger pegs.

JC · 17-01-2005, 10:02 PM

Bucky - how much is this little piece of work worth? I hope not more than $450. Oh, and make sure you keep your big tips (not for me, for you)!

Casper, I think you better clarify the V8 thing. I think you mean most AU series 1 V8s, or most Stock V8s - but then you are talking a modded six running a chip so the comparison is in your favour anyway. But even then, it's only just.

Just to remind you, that out of the list of cars in the AU times thread, there are 8 V8s before we even get to the first six (loxxr6's), 2 of which are 5 litre V8s wih *some* mods. So while you have a car that is quick for a six, there are still a heap of V8s in front of you (and me).

$450! For a 2.5" system i wouldn't pay more than $300 unless it's stainless steel. i got my 3" straight through for $400 fitted.

Thats why I said most V8's. Basically most of the E Series V8s with similar mods and pretty much ALL of the Holden 5.0l V8's with similar mods.

VS Clubsports and SS's, road bait.
But if you want to go nuts....JMM EB I6 NA...13.4 second 1/4. Thats got to hurt.

Nah that doesn't hurt! I don't really want to get into an argument with you in Bucky's thread - hell, why not. He does it.

Anyway, do the same mods to any 5.0L injected V8 (or even *most* carby ones) as that JMM car has had done to it, and the V8 would eat the six alive. It's not like it's a stock (unmodified) car, so comparing it to stock cars is an easy way to "win".

Having said that, I'm just a little jealous that yours puts out more than mine (at last dyno results, anyhow), and it's quicker to boot! THAT's what hurts!

Casper · 17-01-2005, 11:48 PM

Meh, dyno numbers mean nothing. They are close enough to make no real difference.
Time on the track, well, sorry to say but I was fiddling with the car this weekend and I think its got a 14.9 in it without a fuss now. Maybe, just maybe, a 14.8

:

Oh, and I am talking similar mods... at least till the 5.6 and Boss/Gen3 cars are concerned. They are in a different league, no doubt.

Auto 5.0l with exhaust and intake and chip....most wont be that much quicker.

JC · 17-01-2005, 11:55 PM

I reckon mine's good for 14's now too (1/8 mile, lol!). Seriously, mine has gotten seriously quicker since the 3" system went on (Another satisfied Custom City Exhaust customer) - I just wish we had a drag strip in Canberra. Might have to organise a trip to WSID in the next few months or so.

We do - Northbourne Ave - you get lights, terminal speed printouts, and photo finish to determine the winner!

Seriously though, what ever happened to the recent election promises for a dragstrip? I thought there was some approval for it to go ahead?

JC · 18-01-2005, 12:41 AM

"Election promises" and "go ahead" very rarely end up in the same sentence without a "not" in there somewhere. But, yeh. Would be good wouldn't it.

I'm really looking into the WSID thing though - I'm keen to find out how quick my car can go 400m under drag strip conditions. It's really important as you need to know for some of the intersections around canberra (King's avenue roundabout, for example)

Do it JC, take the trip to WSID for your own peace of mind. Some things just have to be known, ET is one of them.

Mr Cube · 18-01-2005, 08:15 AM

OK Buckie... I got the same work done to mine, Pretty much for the same reason (barring the sound being the driving factor)..

I noticed a change up higher so around 100kms put the foot down and shes away.. Round town not to much... But yeah it sounds pretty good too...

I rekon better then the stock exhaust.. I didn't understand the dual setup on the VCT, didn't look like it flowed that well.. But Im not engineer or machanic and when I ran FPV they said they didn't know why it would be set up like that...

What setup is that? Duel Fuel?

Mr Cube · 18-01-2005, 09:01 AM

no the dual exhaust... When I heard dual I expected 2 x 2" pipes..

not the 1 x 2" and 1 x .5" that doesn't go to the tip but points up into the car...

It was a cost saving measure (but $100??, a bit of a joke, really). Only the XR6 VCT and the XR8 got IRS, so why design 2 different performance exhaust systems for one rear axle? They used the V8 exhaust on the VCT, and just deleted/blocked one side of it. The reason the Fairmonts with VCT & IRS get 168kw instead of 172 is that they use a similar exhaust to the live rear axle models.
