Time for a new muffler....

[chocolat1701]

ok since my warrenty is almost over i am now looking to add some upgrades to my LS and i am starting with the KNM intake and the sct flasher, but i also want to upgrade or atleast change out the muflers but i know nothing about them, i have a 04 ls v8 and i will like some suggestions, im looking for performance sound but not really loud when im in idle i like the low prrrrrrr sound similar to the LS on this clip.
