A slightly different Header question...
From what I understand, there is only like 2-3 whp to be unlocked from a header on the RX8. All of the headers out there seem to be equal length headers too. However, I saw one picture of the knightsports one, where it appeared not to be equal length. Maybe it was the picture angle fooling me. However, since there is not a large gain in power to be had, what about sound? What is the sound difference after installing a header? And what would be the sound difference of equal lengthv vs. non equal length on a rotary? Assuming that the knightssports truly isnt equal length, is it the only one that isnt? Like I said, 2 or 3 hp doesnt matter to me, I wont be able to feel that, but I will be able to hear a sound difference all the time, just wanted to know what it would sound like...
-Matt Also, through a combined, intake, header, supercat, and catback, what kind of gains if any would I be looking at? |
intake would give you most of the gains, the supercat would probably lean out your fuel a little bit but you pcm would accomadate for that and take away most of the gains after a short period. I'm guess you'll get +/-5 avg whp throughout the band and maybe more at the peak if that, after a while though it might be even less.

I know that I'm not looking at much whp. Sorry, but 5whp doesnt really matter to me, I wont be able to feel that. But I am interested in hearing this thing scream, my question was more towards the sounds differences...

Hm, just for sound?
$1000 for headers $300 for intake $600 for exhaust $400 for supercat $2300 is an awful a lot of money to spend for just sound. But if you must, do a search there are sound clips of the these things in different combinations. I doubt you'll find anyone with headers though. |
I've got the intake, and the exhaust is on it's way, I'm simply wondering how the different headers will effect the sound, thank you for your input, back the original questions...

Need For Speed has the RE Headers installed. I have two clips posted of his entire system installed:

Nemesis8,
boy does that thing rev quick, what all does he have in it???? beers |
I'm not quite sure - but it is highly modified. He is rebuilding his website currently, so maybe PM him for some specs.
I forgot to ask him where his rear bumper went :eek: Kevin |
for the record... i really don't think sufficient testing has been actually done to declare for sure there is only a 2 hp gain with headers

Quality is truly unknown at this time, but for the price it's worth a shot! Also appears to be a copy of the RE-A (based on looks/design) but without the center exhaust port divider. |
I just looked at the OBX website and didn't see any RX-8 headers. Does anyone have them installed?

I think ddub just received his, but didnt install it yet.

As for an intake some will actually reduce HP (K&N Typhoon), the racing beat Revi intake will grab you ~2.5HP gain. Total gain 12.5 HP and you would have spent ~ $3,000.00 make me sick to think about that. Just buy the Greddy kit for that or get an aluminum flywheel and Supercat. |
