I'm looking for something louder than stock but not obnoxiously loud or drawing too much attention from the cops. I've watched numerous YouTube clips and read plenty of reviews but still can't decide. I'm looking for something louder than the Xforce exhaust and like the sound of the Stillen one if that makes sense...

Going to get carbon fiber mufflers too as they stand out a bit less than the stainless ones.

Thoughts? 12" or 18" resonators?

Cheers in advance!
