I thought it might be a little more appripriate here....

I just designed and made a new front section for my magna.. If any has seen the original seccondary pipes on them, they fall very short of my standards. the pics will show.
They are not polished yet so it will look alot better next weekend.

Am willing to make to order as these particular models are not catered for.
Dont know about performance as i dont have before and after dyno proof. But any1 knows better flow = HP.

That's beautiful work mate.

Any plans for extractors?

**** yeah man thats some nice work

Good to see someone get off there ass and do something custom for the V6!
Dunno im 50/50% on getting one of these made..

Could be $300ish i can put towards my DOHC conversion i guess

Awesome work;)

Have you found a noticeable change in sound / power ? Also have you kept the pipe lengths the same? I was thinking if both sides were and are no longer equal length then that might be a bad thing ???

I wanted to make tuned length but was resticted for space.
The runners were never the same length on the original. Front bank was running about a metre long with the rear about 200mm long.:nuts:

I have the original rear muffler on so there was no noticable change in sound.
But feels a little happier to rev:) . I think i may Have lost a little off idle,:doubt:
But i spose thats what happnes when you loose backpressure.

Any plans for extractors?

That would be a mayjor pain in the A**!!!
But for the right money i would give it a go...$$$$$$$:bowrofl:

Looks good. What price will they be if your wiling to take orders?

Although im thinking to get decent gains out of them you would need to do the extractors awell (going from small to big to small probably dosn't do much at all power wise).

I tried to get quotes on getting some custom extractors done. Most places wern't interested and others said $1000+ plus but no garuntee it wouldn't go higher.

Unfortunately thats the going price, all i wanted to know if it was extractors up to the cat or just the extractor bit..
But for the $1000 and gain 3kw on this car id rather spend $1000 on a DOHC motor and gain some power with that

OK now they are not extractors. i think they are called seccondary pipes.
It retains the original cast manifold, i've just replaced from the flange on the cast manifold to the cat. Now next weekend i will cut off from th Y and it will go into a 2 1/2 in cat and S/S exhaust.
@ the moment ive still got the original 2in press bend exhaust and rear muff.
I will see gains after next week.

The price is ABOUT $250 using the OLD FLEX JOINTS
And ABOUT $400 using NEW S/S FLEX JOINTS.

I will have to work out the real price next week as i got the bit from scrap @ work.
S/S Flex joints 1x 2''=$70 goes inbetween the banks...
1x 2 1/2''=$90 after the Y join and before the cat.

After a couple of weeks just with this mod i'm actually averaging 10-20km more per tank. :shock:

Sorry for the delay will try and get the rest done this weekend...

Got the rear section done today..... Here's some pics.

Very tidy work. I think AMC NSW has found it's new exhaust shop... lol

Hey man what type of muffler and tip is that?
Can you buy those without having to get the whole exhaust piping re done like urs?

Wow thats nice :)

Very Cool, Sweet Job, Art even.

Thanks all... The tip is part of the muffler, and the muffler is a 2.5'cobra performance, cost me $200

I wanted to wait a week before posting.
Sounds pretty sweet too!

OMG the midrange has just got a kick in the guts, not to mention it keeps pulling to 6300rpm..... Got some drone in the 1500-1900 range, freeway speeds are great.
Will be adding another resonator to remove some more noise....

Would you make the front pipes from mild instead of stainless? maybe it'll make it a bit cheaper?

I believe the secondarys off 3rd gen sports are of a better design than exec's and can be bolted on if you can find them..

Yeah i can make em in mild.... but will only be about $60 cheaper.

How would you make it up using the old flex pipes on a car say, like mine, that is in QLD?

quite difficult i suppose.... send me the pipes/flexjoints and using my car as a jig make yours up and send it back... hard process:nuts:

hey there TROTTY. Love your work mate, very nice.

Im pretty handy with a TIG, and most power tools, besides time what specialties are needed to do a job like this? Do you work in the industry? You should if you dont haha

the main thing you need is access to under the car.... you can do it on stands but the back and neck really pay for it...:rant:

Tools needed would be from start.... Welder.. grinder/drop saw, socket set, and if really picky then a die grinder for cleaning the inside of the flanges aftter welding. And general hand tools, clamps, hammer etc... Hardest part would be making the rubber holding brackets...

I use all mandrel bends, so i cut the angle i need, weld on the straight section and then weld my next bend on, etc usually start at a flange and work form there.

And i have my own side buisness doing exhausts... all custom stuff.:D

i like i like

i got everything but pipe clamps, and as far as access goes, ive only ever used stands for everything ive ever done so my neck and back are *expletive deleted* but at least they are used to it.

thanks for the advice anyways mate, last time i asked someone for some advice, they gave me nothing but lip because they thought i was trying to muscle in on their game.

HAHA you're in QLD, dont make rats **** to me.... I'm a helper, not a hinder...:D

And you dont really need clamps but it helps. You will have to weld under the car instead of workbench, just to tack that is.

some undercarrige shots of whole exhaust.... still yet to put in a hotdog, Nice shiny one...haha

That muffler looks like its angry and about to take a bite out of you if you get any closer :)

Heres what it sounds like from inside the car... and a quick power run to 100clicks...
Notice its really freed up the top end....:badgrin:

thats a pretty quick 0-100 time. What else have you done to your car?

K&N panel filter.... and the 2.5inch exhaust.... Tuned for 98, added 3 deg more advance to the dizzy.... Thats it... stock standard. Oh and did i forget irridium plugs....lol

I chose the easy way and installed the secondary pipes from a 3rd gen magna sports. It
also has the better flow where the two banks meet instead of the T junction.

Edit: That was for my old KS v6xi.

Man, im sure I brought this up and a few people said its impossible. can you please confirm that I am understanding this right....

You can replace the extractors/exhaust manifold from a V6 2nd gen with stock ones from a 3rd gen V6. I guess its only the 3.0 V6 though? Any extra work needs to be done??? If its a simple swap, and can be done, I think I will do this quite soon, im sure the crap design of the 2nd gen will beneft from the 3rd gen one. Did you notice much difference?

So he said secondary pipe, or down pipe, The bit that goes from the exhaust manifolds to the cat

Getting this done tomorrow in S/S with mandrel bends w00wp!

']Getting this done tomorrow in S/S with mandrel bends w00wp!
Couldn't that money be used to get your engine into the car? :bowrofl: You better hope the pipe doesnt need redesigning when you get the 6G74 in.

Nah it shouldnt :P
And yeah it could but nothings happening until i get back from visiting you :P
I hope it doesnt - ah well, will soon see

How much?Where?

i dont no if im allowed to post this here but would anyone be intrested in my extractors.

How much?Where?
He said Using new flex joints about $350, or if he can still use the old ones about $250

Well got this done yesterday - Cost me 4 big ones though:rant:
As in Trottys Video (I'll post a few of me thrashing the hell out of it soon) the car just keeps going! No more crappy SOHC Drop off when it gets to 5500, just keeps on pulling - If you cant afford the money for extractors, Seriously consider doing this mod - probably the only thing on a 2nd gen (V6) which will actually increase performance noticeably, friggin awesome to thrash it now cause it keeps (slowly) pulling and pulling.

Told you all.... the exhaust headers are not all that bad.... just that dreaded T intersection! i want pics too to compare what he did and what ive done...if you can that would be great!

I couldnt believe the extra pull to redline either....:redface:

i can do them.... but they will be about $1100....just get the T intersection done..

Sorry about the late reply. No email notifications and totally forgot about it. TUFFTR is
right. Its the bit between the headers and the cat. D&T in adelaide did it. They had one
lying around from a previous owner who had their Magna system put on.

Yeah i mean usually when it hits 55ish in 1st it starts to choke, now, just keeps pulling to 65ish.
Bloody fantastic, even the guy at the muffler shop said dont bother about extractors, this is by far all you need.
I'll try and get pictures Soon, i have taken them but to upload them i might do that tomorrow etc.
They've done a pretty good job from what i could see (amongst the oil lol)

Ahhh thanks. I know realise the whole confusion was because I thought that T intersection was part of the exhaust manifold/extractors or whatever. I guess I should put one of these in, hopefully do it the same time as a cat back exhaust one day.

Screw the cat back. Get this done First, you will notice way more of an improvement over a cat back any day.
I'm gonna be pushing this mod hard! 2nd gen V6 owners get on board and get the downpipe redone!

OK OK you have convinced me, im still not 100% sure I want a cat-back, but I will put this on my to-do list, as surely its pretty easy and cheap. Is it something you can swap yourself or is there welding etc involved??

I was shocked when I first saw that T intersection, I could not believe someone remotely automotive minded, no matter what the cost saving was, decided to make a join like that :nuts:

The one that i make is all custom.... ive nevr heard if fitting the 3rd gen ones before hence why i made my own.... if it works it would be alot easier and cheaper....
Otherwise i am stil available to make these.

If you read my first post you will see i said the same thing about the DREADED T!:nuts: LOL

Like trotty said if this 3rd gen one is better use tat, if not, all has to be custom made :)
