RX-8 Intake help

Okay so before you say search exhaust and such I HAVE for like the last 5 hours I've been trolling every post lol...

I'd like everyone's opinion as to which intake sounds the meanest/loudest

from what I've read the hp gain basically is so little im not even going to include it in this discussion, im asking about sound

based on older posts most people said the following were some of the best sounding, please correct me or let me know your opinion! thank you!!!

umnitza
weapon r secret weapon
k&n with mod
mazdaspeed cai

I've had both the AEM (same design as MazdaSpeed) and Racing Beat, which are the two favorite aftermarket intakes, and I thought the AEM sounded louder.

I have personally seen intake temps well over 150 degrees F with the K&N original intake. These readings were recently taken on a warm day in Arizona.

the umnitza (simota) intake is the loudest out of them all i dont care wat anyone says.. it rattled my dash at 8000rpm..buutt i have to agree with alz0rz i did lose alot of power and it was very noticeable..im running a aem (same as mazdaspeed) now havent had much time to run it had some problems with it but its decent sounding and gives a few extra hp..

hey man I dont know if this is a little too late but I highly recommend the AEM Cold Air Intake, I have installed it in my Rx-8 and there is a pretty big noticible difference in the noise, you wont hear it when you taking off softly but it will kick in when you really slam, and especially when you go above 4,500 rpm, this is where the HP really kicks in. it get even louder, so AEM is the way to go.

thanks guys, seems like AEM is the way to go, won't lose any hp and sounds good.

now, for the exhaust,
greddy headerback?
b&b headerback?
racing beat /w cat?

opinions?!

keep in mind this will be with aem, plan on purchasing both next monday
Thanks guys!
i've seen plenty of members buy 2-3 exhausts or intakes before they found the one they liked most and im trying to get a overall feel of what everyone has experienced first hand and likes the most. without having to go through 2-3 eh

yeah first off before i go on i would like you to know that i am not trying to disrespect you or your knowledge on tech, were both Rx-8 owners, we share a rare blood line. now I have notice that when my 8 hits 4.5k rpm i do notice a bit more pull and a slighter aggressive tone, it maybe not have any gain but i does breath better allowing it to burn all the fuel more efficiently, i dont want to explain that cold air is more dense because i know you already know, but if you notice on a dyno run the results show that there is a peak in hp around the same rpm, so in conclusion, the CAI just enhances the performance, please correct me if i am wrong, no offenses will be taken, i am just trying to learn more and more about the 8.

yep.. that's the noise maker.

You'll see them come up on here for sale from time to time. There was just one yesterday that already sold.

Not sure what the avg price is for them.

if you want noise - just cut open your stock intake box and put a k&n cone filter on there...


lots of noise plus similar results to the k&n series 2. Little to no power gain, turbulent air flow and heat soak all for under $30.
