HM headers
Anyone use HM headers? Paceys are the aesthetically better option but i've heard HM are a bit better in terms of performance. Opinions?

V6 or V8?
HM Headers have a broader power band and will give extra power from just above idle, whilst Pacemakers dont really kick in til around 3000rpm.
Pacemaker will give you more MAX power though, just the power band is not as broad as that of HM.
Pacemaker look better and are better built and imo they are the better option.

yer hm are made outter thinner material but u can get it in stainless/mild steel more power all over paceys from what i have read just dont look as good and they are tuned where as pacemakers arnt. im goin HMs when i get the $$

im goin HM headers when i get tha cash. from what i have herd and read they hav more power and alot louder over paceys and they are actually tuned to your cars engine where as pacemakers arnt. HMs are made out of thinner material tho but i dont think ur gonna be wearing a hole in them any time soon even tho they come with a 10yr warranty. they come in mild steel or stainless.

from what i read hm headers shit all over paceys louder more pick up and power. they are designed specifically to ur engine where as paceys arnt. only bad things i know about em is the welds arnt cleaned and dont look as good, HM use thinner material and sum ppl may think its too loud
im gettin hm's
V6, i've read the large thread on "that other forum" compring the two but i've only ever been in cars with paceys installed, I was hoping maybe someone here would have some feedback on HM.

I have been in a car with HM and I honestly prefer being in my mates VL with his paceys. Offline the car is no different but VN's are pretty good offline anyway. Top end the Pacey's will eat the HM headers up.
Pacemaker all the way

well im goin HM i dont see the point having the same setup as every1 else. at the end of the day its going to be no diffrent to any1 elses. I read alot of good things about hm's and the only bad things i herd was the material is thinner than pacey and it may be too loud for some .

My mates got HM's on his vs and they sound alright but my pacey's on my vn are heaps louder. If you listen to both cars next to each other the vn's idle sticks out.I wouldn't knock pacemakers i reckon they are better than HM's.

The truth is no one knows what are the best headers for the v6 the companies don't even bother to list the length of the pipes, HM are often said to be the best but as far as I can see in the few brands I've seen pictures of none of them are long enough to do anything magical.
May as well just run the factory tube headers from a series one VN

If pacemaker are better around 3000rpm wouldn't the be the best bet as the torque really kicks in hard on the Buick's @ 2700rpm. Mid range would be impressive great for overtaking and bursting out of corners.

But the Pacemakers have the longest runners of the lot. But yeah the VN has great downlow torque anyway, so on a VN I reckon the pacies are a great matchup!

With my car i feel a hard pull about 2700rpm up to 4300rpm then it changes.
But thats like going around a corner @ 20kp/h and still in 2nd and then accelerating up about 75% throttle.

What other brands of headers are ok? I've been thinking about getting some, either new or second hand (ebay)
i'm not too concerned with top end power, mainly down low torque. Oh and a nice sound is always important

Ive got a set of pacemakers installed on my VN V6 with 2.5" straight through (stock cat). When I first put them on I could feel the responce as soon as I touched the accelerator at idle. But I haven't seen or herd about HM headers before, So yeah looks like the ball is in your court man.

Extractors are not made for low end torque. But the closest set of headers for that job is HM Headers but remember they are also very expensive.What other brands of headers are ok? I've been thinking about getting some, either new or second hand (ebay)

Depending on what you want from headers and whats been done to your engine the best brands are Pacemaker, HM, Genie and of course Di Filippo.

Ive got HM tuned length on mine, no complaints here
I used to play sports. Then I realized you can buy trophies. Now I’m good at everything.

Yeh i'm leaning towards the HM tuned length headers, i'l have a chat to the guys at tidd bros when I go to buy them.

Pacemaker etc. are also tuned length headers...

They can be tuned length headers, tuned length headers are good for top end power, most headers arnt tuned length unless you ask for them. A mate had some tuned length on his worke falcon 6, and the thing sounded like a skyline. MY car is the only V6 commo i know of that has through all the people i know though
