^ Crazy C. You're going to be the official rasp judge during my trials, I need to swing by and show ya da white nightmare.
Nice post.... But stock mufflers make a **** ton of rasp with aftermarket exhaust before them.
Even tho its beaten to death, I love exhaust threads. They are the most fun. 
When i hear unequal length headers, I think of turbulent flow. Turbulent, fast flow plus poorly designed flex section would result in rasp.
in order to decrease that rasp, i would think u either need to smooth out the flow or install a flow resriction to slow it down a bit and decrease its energy. installing a stock muffler should eliminate much of the rasp, resonator will take care the rest.

A test pipe will exacerbate the problem, but it won't cause it.

It's interesting you say that, because I've been having this feeling after installing the Cattman headers that the last bit of rasp I have is actually due to the 2k Max muffler I have. My setup is Cattman headers->resonated test pipe->resonated b-pipe->2k Max muffler.
There is only a slight rasp when I'm WOT, and now there is none when I decelerate in the 4-5000 rpm range, but I think changing the muffler could help. I wonder if having a 2.5" exhaust all the way to a 2.25" muffler inlet could cause problems. I'm really thinking about the G35 sedan muffler since it's 2.5" and will still be very quiet. Thoughts?

Sorry Aack mang, but u gotta prove this to me.
I would think that a stock muffler would eliminate rasp or minimize it so much that its just about gone.
Any video links? Are we talking a performance muffler like the 2k or stock 4th gen muffler?
I think a stock 4th gen would eliminate rasp.

But I'm with you if you keep a completely OEM catback and not just the muffla (To a point, headers + OEM catback will result in rasp)
Maxrider, brb, imma edit this with a video on what I'm talking about, it's not a maxima but it applies toward pretty much all cars....
Bah, if only we were behind the car during the dyno you'd hear the bees in a can sound.... It sounds terrible....
You can kindof hear it, but it does the car A LOT of justice, it does not sound that good from behind.
This car has 3 mufflers btw (OEM catback)

You should see the pos flex that came on mine not sure which brand i ran it for a month before i couldnt take it and took the sawzall out when i saw the flex up in the light i could see daylight from the inside what a pos and it was only about 1.75 in in the inside dia. And it was only a couple years old.I put a longer and wider one i got from napa so its a straighter shot i had to make a new mount and header wrap the pipe by the floor board i have the cat and the stock b pipe still and no muffler just a nice pipe and tip and NO BEE CAN NOISE to speak off people tell me it sounds amazing all the time

Um, I still had plenty of rasp even after getting rid of the test pipe and replacing it with a resonated one. I would say that got rid of 20% of the rasp. The Cattman headers got rid of 70% more. I say I only have 10% left to go, and I'm thinking that a G35 sedan muffler with the 2.5" inlet (instead of the 2.25" inlet on the 2k Max muffler) might help with that last 10%.
A test pipe will exacerbate the problem, but it won't cause it.

I installed my 03 Max Oem unit and it removed all the rasp, I also think tip size matters in sound quality.....I also installed an extra Cattman 2.5" x 22" resonator and it's freaking smooth now!

Maybe yours was replaced by the previous owner...cause the flex section on my WSP ypipe is definitely 2.5" ID.....
