since i'm upgrading some engine things that will require "free flowing exhaust" i was wondering what is out there that flows freely but isn't much louder than stock. if not just a hair quieter. i'm a young floogie but i have never really been able to deal with a loud exhaust. any ideas or thoughts?

Silent exhaust and GTO just doesn't go together~!

Most aftermarket exhaust systems I heard are louder than stock. Since you have a '06 GTO your 2.5"ish exhaust is pretty efficient, even thou it has its crimps in places. Most aftermarket catbacks are 2.5" anyway I think most of the gain is replacing the muffs.

Yes you can do that. Depends on your pocket and your state smog regulations Long tubes with catted mid-pipes would be better.

JBA or Magnaflow would be good options for you. Over at ls1gto.com those are pretty common recommendations for people who don't want to go too loud.

Heres a link to a huge collection of all sorts of different exhaust combos:

i have the jba and daily driving isn't too loud and has a nice tone. on wot it is super loud and very throatty. i think there is a thred on ls1gto that has sound bytes of the differnt exhauset/header options.

From my experience, the Magnaflow system is the quietest. At idle, it is very quiet. However, at WOT it does get louder and raspier, as all straight-thru mufflers will.
