Your engine mods have alot to do with how your car sounds. I noticed a HUGE increase in exhaust tone when I put a new turbo on, when I put a higher compression 6-bolt with a ported head on, and even just porting out the exhaust manifold/exhaust housing.

Be thankful your car isn't really loud, I kinda like the way how stock DSMs sound with just an exhaust. Its smooth and quiet.

i have heard that the exhaust packing in the muffler has to stiffen and get packed down and once that starts to happen the exhaust starts to get louder. is there any truth to this?

is this 2.5" diameter echaust piping from turbo and back...? 3.0"?
You say Cat is out right? so how many resonators are there in the exhaust system? 2 maybe?

3.0" exhaust is louder then 2.5" exhaust, also the resonators help quiet the system down a bit, and I bet you have at least one in there.

If so, go to a muffler shop and have them remove it (or 'them') for straight piping, that'll give you that louder tone you're looking for.

my piping is 2.5 off the turbo then i turns to 3 then it hits 2 resonators and then turns to 3.3

That's why your exhaust is so quiet

any thought on the whole getting louder over time idea?

I've only got a 3" high flow cat and 3" custom catback on my 1g, and its very loud. But it sounds very aggressive and it probably sounds the best of any i've heard in person.

keep it quite. You dont want it loud. People complain about me all the time, and it kinda sux when youre driving and trying to chat on your cell phone at the same time.
