Need advice on Custom exhaust
 

So im thinking of getting a custom 2.5" turbo back done and I wanted to know if anyone has any experience with the hks carbon titanium muffler. I am considering that muffler in the 3 inch form with the 4.5 inch tip. Anyone know how loud it would be ?

I have a cheap ebay muffler that is modeled after the stainless version of that muffler, and while it is very nice sounding at lower rpm's, it does really begin to drone at higher rpm's. I have a resonator sitting in my room that I am going to install here soon. I really like the ebay muffler though, sounds real burbly and real good at idle.
