New Headers

[Yanayaya]

Yesterday my new headers arrived from VPW. I'm really happy with them, the quality is excellent, now to get them fitted. Initially going for the decat approach and then depending how that goes will have sports cats popped in at a later date.

It's loud without the cats . Are you making the decats yourself or getting a shop to do them , or modify the old cat pipes with the supplied flanges ?

I've emailed you chap lol I'm going to need advise on a few things and you're the man with the plan

If you don't mind me asking how much were they all in shipping and import duty

Very nice kit. What are you doing about (de-)cat pipes?

Initially I'm just having decat pipes made up. Later down the line I'm going to have sports cats fabricated into them.
So for a period of time it'll be Nascar level

Look good nice and shinny

These look nice. What size are the primary and secondary pipes?

I have a pair of X-Force 1.3/4" headers that are brand new as they aren't large enough for what i now want to do. :-(

1 7/8 " primary with 3 1/2" collectors , for Monaro though not sure what size VXR8 ones are if thats what you have

[StuartOwen]

Look very nice, I'm tempted by a set of these at a decent price like that, what are they like to say the wortec headers that Monkfish sell? (except cheaper) I'm assuming being stainless they would still be ok for ceramic coating, I'm currently looking at trying to keep the temps down in the engine bay, but when I search I end up looking at cam's, header, etc lol I'm easily side tracked.

I have custom made headers and cats made for me by AAS in Newcastle cost was about £1000. I had 200 cell cats made but they will make decat pipes to fit but wont fit them thats down to you.

This work was done about 5 years ago so price might of come down since then. Lot of the scottish guys have headers From AAS.

Current cost for AAS mid-length headers, sports cats, angled plug lead(s?) and O2 extension cables is £1300 fitted. (Guess where I'm going tomorrow!)

I was seriously tempted by these Proflows, but I couldn't find anywhere local who I'd be happy to fit them and make up cat pipes. I don't have the time to fit them myself, so I'm going with the lazy/expensive solution.

See when i had mine done there was no mention of that extra stuff but i was about the second person t get it done on here.

Doesn't sound that bad a price to be fair with the fitting, When you say mid-length is there different lengths they do or is it just that's what they call them. Bit of a hike for me up to Newcastle (I'm over near Liverpool)

[StuartOwen]

How come they wont fit the cat pipes for you? Emissions etc I assume or because it would be an MOT fail/not suitable for road use.

The Proflow headers above are classed as longtubes, in that the lengths of the primaries into the collector are "long"! This contrasts with "shorties" fitted to 5.7 VXRs. The AAS headers are somewhere in the middle. They will make longtubes, but they seem to discourage it due to clearance issues and the potential for knocking. More expensive too. Others can discuss the relative merits of primary diameters and lengths.

Incidentally, I'm on Merseyside too. 3 hours drive and a return by train. Leaving the car there for a couple of days, you're more than welcome to see the results.

Performance aside (not sure what you lose/gain vs. long tubes except in vague terms), the AAS medium lengths are well made and a good compromise between ease of fit, ground clearance, price, and are well made.

Sorry Yanayaya, we seem to have stolen your thread! Please keep us informed of how you get on with your Proflows - I would have most likely got the same if I had the time to fit them myself.
