What type of Headers you got?

im thinking of getting a set of headers before the market crashes again and was wondering if anyone here uses these and what your opinions are

actually i hope the market doesnt crash anymore...

anyway, my impression of the racing headers:
i had them on before i changed the catback and other exhaust mods.
so my impression of it compared to stock manifold at the time was: it didn't really lose any bottom end torque which was surprising, engine revved a bit smoother, but there's not much noticeable difference on the top end, i reckon other two free flowing headers will also do the same easily as well despite the price difference.

After I've put on the cat back it felt very different, mid-range improved while the lower rpm torque was retained. though theres still not that much difference on top end I think. no amazing max hp gains on dyno either. I dont know if the mid-range response came from the catback or if the effect of the extractor multiplied with the more free flowing catback. but then again I've driven other member's ae111s like DA's or evaril's and while they both have catbacks, their cars are no slower than mine I think.

now the bad parts:
problem with the racing header is that it hangs down really low, and one of the big flange kisses the ground quite often. I've recently lost an exhaust bolt on that flange because of that too, had to get that replaced. the weld on the bracket was pretty weak, pretty much all the jap reviews i've seen on the racing header have mentioned the bracket ripping off from the exhaust itself and they had to get it rewelded and reinforced, and mine was no exception..
plus it's a lot heavier than others too.

i got sucked into buying it because:
1. it looked nice (the photo from the HKS website.. lol),
2. the theory of bridged runners to reduce backpressure appealed to me at the time,
3. it's 4-1, "theoretically" it should get you more max power (well hks says its 4-2-1 since it's got a chambered collector, but the design of it really works more like a 4-1)
4. most jap reviews i've seen said positive things about it in terms of power gain, even though none of which have shown dyno charts, since its expensive to dyno a car in Japan. So the Japanese owners just go by their ass dyno. I've found out afterwards that some reviews are pretty exaggerated.
5. There are no other ae111 owners that i know of 2 years back, and certainly didnt know this forum so i couldnt really ask for any opinions or questions except for reading random jap reviews.

I really think you'd need some serious engine internal mods to get the most out of it, like if the engine's pulling 180hp at the fly or something, even so im still not sure if it justifies the difference with just getting the Y pipe remade. the AE111 race cars in the fuji champion race actually retained the stock 4-2 section of the extractors, and just remade the Y pipe and catback. some of them still put out 180hp with just balanced engine internals and stock cams, according to hyperrev magazine i've got here.

on the other hand, hks super header and the fujitsubo are almost identical, so i'd go with whatever's cheaper. the hks super header doesnt seem to suffer from the problems the racing header have either (weak weld on bracket). So if i have a choice again I'd save the extra money by getting a 4-2-1 or even only just change the Y pipe, save the difference and use it on other things to make the car handle better or actually go faster.

yeah its cool
one of the reviews you've asked for was racing header, so I just put down what i think.
if you could get the super header for cheap then go for it... its almost identical to the fujitsubo so i really doubt you'll find much difference between the two

you can just get a metal cat fabricated locally....
metalcat, catco, xforce all have nice high flow metal cats available for a lot cheaper than the sard cats...

aka Hyper Rev 4...
it wouldn't make much difference if you got HKS metal cat or not... but local ones will be a lot cheaper.... plus, i don't think HKS makes one for our car... only SARD and Kakimoto makes it for our car....

i have the HKS super header.
but i have a stock cat back and running a cat so i only really notice a smell from the steel and a buzzing noise as the gas passes through the flexi section.

but when it was straight through it did make a difference, never got it tested or anything.

If you're running a OEM JDM CAT, even matched with the HKS Super Header II as long as the CAT is in working order, I didn't notice much if any restriction. Changing to hi-flow made only a small difference imo have to test on the dyno. This was with FGK PG on the butt end =P

I've heard very good things in the past regarding the "Cusco P-Ball" manifold. Does anybody on here have one fitted? In the near future I'm going to see if anyone would be willing to lend me a aftermarket manifold so I can copy it. There's nothing freely available for the AE111 at the moment and I'd like to change this, I'm working for a motorsport company at the moment so if someone had a manifold they could lend us we could make up copys and sell them on here for quite a decent price! The same guy who made the de-cats was in the process of making a manifold but it seems to have all fizzled out?

Does make a bit of a difference if it's a mandrel bent straightened system though.

I had thought that the factory system was 1" 7/8?

My car had the 2.25 on it when I bought it, so can't really compare I guess.
