I had the muffler shop make a custom true dual with two resonators and its perfect now. Not too loud, not too quiet, just right.
it's disappointing to hear that the evo2 can't handle test pipes properly though
can't wait to hear those sound clips nonetheless

I mean, the sound was badass with just test pipes and the system except for that one whistling can sound that was being caused by the x-pipe. Here is what was causing it.
As you can see, if you dont have cats there is just too much exhaust pressure going into one pipe. The first part of that single section is small, so its smaller than any aftermarket y-pipe. That is what causes the unusual noise.
If greddy simply redesigned it so both pipes connected into one huge section without a reduced section before it, it wouldnt have a weird whistling sound.

ah ok i understand now
what do you estimate the diameter of the joint(s) to be? is the piping 2 1/4 on each side, merging into another 2 1/4 pipe?? if so that's smaller than stock! that would probably explain the aforementioned whistling

Greddy should have had a nicer x-pipe design because this one blows. Everything else in the kit is great except there are too many freakin pieces and its annoying lining everything up perfectly so nothing hits the suspension pieces.

The wheels are rota R45R's all around. They are 9.5" wide wheels and honestly I love the nismo wheels but I hate the fact that they cost around 2k dollars without tires.

Here is the vid.
I think the weird sound is from my camera. I even revved it to 6k and it doesnt seem like 6k on the video. Very weird. Here it is http://smg.photobucket.com/albums/v2...ture162687.flv

rasp at all? Sounds like it may be raspy if you have test pipes. sounds good though.
The big can setups like nismo have a weird sound to them. with test pipes, they make this annoying metal in a can sound, which may be attributed to the Z's howling note to begin with. That exhaust is dual can so it doesn't have that sound. sounds like a bear :-D
