Okay. I think I've done my research and I'll post what I think sounds good to me, and then I'll ask for suggestions. I looked around on the topics to do some research because I would love to add an exhaust system with intake very soon. I'm going for the exhaust first since my budget is somewhat low, since the exhausts are cheaper than the intakes. Now, I LOVE the sound just from the clips, of the Borla pro xs mufflers. I think they sound really nice, many people on here say that they are really nice, they hit the spot. I also really liked the sound of the magnaflows as well. I'm primarily looking for something that sounds good, but doesnt have bad drone, expecially in the cab. I heard that the borla's are very good because they aren't very loud but they still give that nice sound, that is what I want. Anyone know how the noise is in the cab for magna's? I'm looking at borla's primarily, but would like to see some more clips of them. Preferably on I4 since thats what i have. Thanks a bunch and I'll greatly appreciate the comments.
