Looking for a new exhaust setup

Currently have the full cat-back Highline Tuning exhaust, but I'm selling it soon. I know what straight pipes sound like, I know the pros/cons, I know what some people may think about it. I've noticed many of these threads do stir up some heat sooner or later. I'm not creating this thread to draw arguments.

I'm thinking about a 2.5" Y pipe, to 3" straight pipe all the way back to either muffler or just tips.
Now, how should I go about the end of my exhaust?
Are there any decent mufflers out there for our e46's with a single 3" inlet and 2.5" tips?
Or would I be better off going with no muffler and just running a couple tips? Would it be significantly louder?
This is really the only thing I need an opinion on.

Again, please no bashing or anything.
No, I won't lose any HP/TQ to notice any difference whatsoever.
No, it won't be too loud.
No, I won't attract the wrong kind of attention.
No, your bitching won't do anyone favors.

So the muffler shop I went to quoted me at like 900 bucks for dual 2.5" pipes from the cats back. -___-
That can't be right.. he said most of it is labor dealing with bending the pipes and everything, but still.. no way should it be even close to 900.

For the Highline exhaust, there's no resonators or anything, so wouldn't straight pipes with a muffler sound relatively the same as my exhaust right now?
Should I just go with tips and no muffler?

I have a buddy doing my exhaust for my 330i. Its a Y pipe from the headers to a 3" Stainless steel single pipe. Also is building me a whole made resonator and muffler from 6" Stainless. Cost is right around $600. Here is a pic of his work for a for a LS powered M3

I'll call some muffler shops tomorrow and see what custom straight pipe work I can get done for cheaper than 900 lol.

Maybe I'll just make it louder by just cutting the muffler off and putting on tips?

That's what I plan on doing. I know a lot of people probably think that's stupid, but honestly, with the 2 stock resonators still on there, it sounds fantastic. Not too loud, not raspy at all, just a deep, low rumble. Plus once you put some nice stainless tips on it, no one is ever going to know its not a cat-back setup. Plus for around $200 depending on tips and labor costs, you really can't beat it
