hey guys, noob here at the forum. i'm looking for some advice/opinions about this. I don't have the cash for a full cat back system, so I was hoping to just replace my stock mufflers with some aftermarket (preferably Borla chambered) mufflers. Have any of you guys done this or had a muffler shop do it? Does it require a lot of fabrication? And if not the Borlas, are there any aftermarket mufflers out there that are pretty much a straight up replacement? I'm looking for a little more rumble than stock, but something that doesn't drone at highway speeds. Thanks for the info.
