Well, while we are on the subject, I will tell you guys my unique situation. A little while back I bought a nice Apexi N1 muffler, and went to the shop to have it put on, I figured I would get full exhaust some other time. (Since then I have been having big plans for a turbo so it's a good thing I waited.) When he took off the stock muffler I had the bright idea of thinking it might sound nice with it off. I revved it, and it did...extremely so. Guys, I'm really picky about exhaust sounds but I love a good sounding one. I love a really deep, clean constant sound, as opposed to the growl of a mustang or the drone of a civic, I hate both equally. So I told him to try the muffler on for a second, and it obviously sounded better without it to everyone around me. I figured I'd sell the Apexi, save some money and have a great sounding exhaust, and that's what I did (I welded on a nice lil chrome tip for looks though.) Right now, it is not unreasonably loud, but it comes down to this...
When I go turbo, I want to replace the restricting 2nd cat and resonator and put in some bigger piping, like 2.75-3.00" depending on how much boost I'll be running. It's already quite loud enough for me (and the perfect sound) so how much will taking out the resonator and getting bigger piping effect it? Also take into account that I'll have a turbo running off it too, installed probably around the same time.
