Which Headers

[BlueDevil]

I'm looking at fitting long tube headers to my Monaro ( 6.0 ) but which ones are best. I've seen a number of options wortec, AAS and some others from Australia.

Does anyone know what the differences are and if they give different overall performance.

[MedwayMonaro]

There are a number of options, I'm not sure what the differences are on power but I guess that will depend on the set up of the car.

Wortec and AAS do them but they tend to be the more expensice options. The Pacemakers are available from Oz but these are not stainless steel, but are considerably cheaper and fit well. You also have VPW headers which are both cheap and stainless (but don't come with cats) plus some other Australian ones that I'm looking into at the moment.

Need to FH a power run but my proflow headers were well priced and made. Look to be a similar design to the pacemakers.

1 7/8 in to 3.5 inch. Come with a 3.5-2.5 converter than can be cut to size. All gaskets and nuts.

Cheap for what you get too.

Botox, Pacemakers are stainless steel!

Interested in this too as my cat went today so I've started looking into it. So many options. I've emailed some UK companies and going to look into Aussie options too.

Just not in our climate.

Same planet!

I hope you guys know about stainless grades!?

[neiljohnson]

I removed the pacemaker headers from Medway monaros car & they have corroded rather badly for the short time they were fitted regardless of what they are made of!

[vxkev]

There are many grades of S/S and exhausts are not the highest grades like surgical or nuclear grades, they do rust especially where there is cross contamination like bolts made of high tensile steel also salt as in road grit erodes S/S once it starts to corrode it can happen quite quickly and make holes there are also cheaper so called S/S with nickel added to the carbon steel instead of chromium which are magnetic the better quality S/S are non magnetic.

[Coatesy351]

I have pacemakers, they are not stainless steel.

[rich24v]

The ceramic coated pacemaker headers I got IMHO are mild steel.
Very magnetic, exactly the same as mild steel.

[L2VXR]

Proflow headers (from vpw ) are non magnetic 304 stainless

[Aitch 'H']

I've got AAS headers and they're still very shiny stainless after nearly a year on the car, no idea what grade stainless they are though!

[Kiwi LS2]

Is 304 stainless what we should be looking for, the whole way down the exhaust path? TIA.

[Yanayaya]

I run long tube headers on my Monaro and they are ProFlow from Australia supplied by VPW. They are very good, lovely build quality, they do sit quite low so speed bumps become a little bit of an issue and that's at the standard ride height of the car.

316 would be better as it contains molybdenum so better corrosive properties to salt, and certain acids that are in exhaust gases

As usual, plenty of excellent advice from the guys in the know....
I'm following Aitch'H' and an AAS exhaust is booked to be made/fitted to my ro in 2 weeks time. As the saying goes 'you pays for what you get'

Totally agree on the statement you get what you pay for, but with all the options that seem to be available with such a variance in price it's hard to determine what to go for.

Thanks for all the advice so far, more homework is required.

I paid £700 for my headers (no cats) I believe it's £1100 with the cats but you'd be happy with them. I know MedwayMonaro and neiljohnson who took his headers off and they're covered in surface rust. My AAS headers as I've already said are still shiny and have a lovely bluey heat pattern all over them where they heat up and cool down again (you know looks like oil spilt on water) they're 1 5/8" going down to a collector at the 4 into 1 point that you can get your fist into! They don't hit the floor, even over speed bumps, and have made the car really rumble with the rest of the exhaust set up I've got. For what I paid I couldn't be happier so well worth a look mate
