    Default Advance vs Pacemaker Headers. What to get?

    Hey,

    I'm finally getting serious about extractors. I can't justify RPW and have narrowed it down to pacemaker and advance headers.

    Advance:
    1 5/8 primaries, press bent. Interference design. 2" secondaries.

    Pacemaker:
    1 1/2 primaries, mandrel bent. Tuned design. Unknown secondaries

    Given I've got a 4 speed auto, I think better mid torque would be more beneficial from an interference design. If i had a manual I'd probably opt for a tuned design coz I would be able to keep the revs in the upper band.

    So yeah, I'm thinking Advance (plus they're local in adelaide!). Has anybody got any other reasons why I should or shouldn't go with these??

    **EDIT** This thread isn't meant to be a 'my extractors are better' **** fight. I just what peoples opinions on what they think would be better for MY car

    i was the prototype car for advance headers, bloody good (compared to ralliart stock headers)

    more torque throughout the range (although im manual) from what i can feel

    mine may be slightly different to yours though, as you have an edited product from mine (being the first built)

    talk to mike, mikes a good bloke

    or adam from fishers (he's the dealer for them )

    good luck

    i recently heard from the local mitsu parts dealer they have walker/lukey extractors fore magnas now ... for 400 ish or something .... dont know the stats of it though and neither do they ... they r only new and i cant find anything on the net , so a phone call would be in order if u really wanted to know ..


    i think if walker has put the time and effort into making a set then i reckon they would be worth a look as they would know they have to compete with pacemaker so these must be up to a certain standard .

    Pacies, there the only mass produced extractor I've seen in AUS with the stem into cone secondaries, plus press bent is nasty. There seems to be a bit of negative sentiment in AMC towards pacies but you compare them side by side to most extractors and they **** on them, the fact that magnas dont seem to pick up much is probably due to a decent factory design. I watched my friends 302 XE pick up 15kw on our dyno between pacies and stock.

    in normally aspirated engines, mandrel bending is not required, and can result in a torque loss

    proven on my mates dyno

    I've seen reports showing the 'lack' of flow between press and mandrel. It's bugger all difference, and considering the advance primaries are slightly bigger I'm not too concerned about press bent.

    Pipe over cone is a +ve for pacies though.

    I forgot about these. I'll defiantely investigate since I might be able to score employee discount frome someone.

    mike was the guy who used to design the genie headers, back when THEY were the shiz...

    knows his stuff, and based the design on the ralliart high comp engine, so the flow would be better for a verada/ exec auto i would imagine?

    To add to the confusion:

    Lukey:
    1 3/4" primaries, pressbent. Unsure of what design it is, tuned or interference (my guess is tuned). These are a bit more expensive than the advance headers. However unlike the pacemakers and advance headers, the primaries are butt welded to the plate. The piping doesn't go through the plate, so isn't as strong.

    Only pluses are the 1 3/4" primaries.

    How the heck do less restrictive bends lose torque? And if you say back pressure, so help me I'll come down there and smack you
