no im all stock, but the res will take the sound you dont want away and let what you do want to hear come out.
i willing to bet what ever mufflers you put on, with a res it will sound cleaner.
from what i hear on the youtube and what not, they all sound good idling, (aftermarket mufflers) but when revved up ( or getting on it) they sound like crap with out a res.
that is why im opting for a solid stock exhaust when i get to modding, i haven't heard anything i really like except for a borla set up, and who really wants to spend that kind of money. but thats me and my taste.
