I know this is another exhaust thread but..
 

What I am looking for is the sound that is very deep, and not tend to be too loud(enoughly loud is okay)... and I looked up compared the agency power,greddy SE,racingbeat rev8 exhaust and... just the sound from Youtube isn't much of a sense to me so... what would you guys recommend for a deep, enoughly loud? I am kinda on racingbeat rev8 exhaust side now... and I am using racingbeat intake with airduct...

I would go with HKS Hi Power. People say they are super loud and deep. But, I have bunch of friends with evos and stis, and they all have turboback exhaust. No cat,only 3" test pipe. They are loud. However, compared to those rally cars, 8 is quiet.

Well a deep loud tone would be an HKS hi power exhaust, although its only single exit, so if you like the looks or not, you can always mesh the other side.

Greddy SP2 is pretty deep as well, they are discontinued but you can find a used one for cheap im sure.

It's a rotary, why would you want it all deep and throaty? Let that rasp ring is what I say.... But whateve's. It's your car. Listen to good youtube clips turned up loud on a GOOD surround sound system for the the best idea of what you are getting.

Oh and you want loud, roll with your exhuast off for one, day it's TOO loud, stupid loud.

I had the greddy se, it puts out an AWESOME sound without being too loud and looks second to none but it's only a 2.5 inch system so don't expect anything on the performance end. I just switched to the racing beat rev8 and it's definitely quieter and a bit higher pitched. I miss the sound of my greddy but the performance of the rev8 is worth it IMO

borla or racing beat.

they are deep..

it all depends on what you do with the midpipe.

beers :beer:

I use to have the agency power with midpipe and is extremly loud, I remove the midpipe and now I just have the cat-back and the sound is awesome, and now I can hear my engine again... I hear one greddy se and I fall in love with the sound but I prefer the look of the agency power, is bigger! And cheaper :p just the cat-back cost arrounf 550 from race roots.

I have a rx7store high-flow cat and GReddy Se exhaust. It's pretty tame at idle but definately loud under load. I love the exhaust tone with this combo. And the best part is no CEL.

Hope you guys dont mind me asking, but the Greddy and AP exhausts, do they drone the interior?

Not in my opinion. I'm speaking for the GReddy SE.
