Monaro LS1 headers from Oz

[mjf93]

I'm looking into options for header upgrades, with sports cats. My car is a 2004 5.7 VXR, so it has 1"1/2 tubular manifolds as standard, as I understand.
I want to upgrade to some 1"3/4 or 1"7/8 headers with sports cats to get a little more noise, and maybe some mid range torque.
From reviewing the prices here in the UK vs Australia,they seem a lot cheaper in Australia. Has anyone had any previous experience with importing them, or can recommend a company that they have used in the past? Or is it simply not worth doing?
Thanks in advance.

Unless you're making over 6-700hp n/a then 1 7/8" would be overkill.

If boosted, 1 3/4" will easily take you well beyond 700hp, and then some.

Thanks for the info, the car is pretty much standard so I would imagine 1"7/8 would be overkill then. I am potentially looking to upgrade the cam at a later date, so as long as it would facilitate that then 1"3/4 seems like my best bet.

I used vpw.com.au and couldn't fault there service, 1 7/8 longtubes but had to fabricate my own cat pipes so workout the extra cost for that though it's a lot cheaper with decat pipes.
Payment had to be bank transfer and they turned up at my door in about 7 days

Thank you for that, I will drop them a line.

I was part of the group buy that ringram organised about 18 months ago - they are Pacemaker items with hi flow cats and I've also attached that to a Wortec cat back. I see you've got an LS1 VXR, same as me, so I *think* if you get the same parts as I did they will bolt right up to the Wortec (if that's what you've got).

I got 1 7/8 headers on mine, as they were the same price as the 1 3/4.

They make a tremendous noise even with the centre silencers in - you have been warned!

Pacemaker also offer a ceramic type finish which I didn't get but others did (jameshsv has this) - I would go for this next time.

I do have an LS1 VXR with a Wortec cat back, so my system should be the same. Have you got a link to what you purchased? Are they stainless steel items, or mild steel? Was the group buy through the same company as above?
I run my Wortec without the centre silencers in, but it is not a daily drive so I'm not too fussed on it being too loud.
Also, did you go for long tube or medium length headers?
