i own a '04 prerunner 3.4v6, and installed both magna and flowmaster. magna flow was really good, deep sound. The flowmaster i installed after was ok, it was deep and had a more garggling sound. As far as performance, you're not going to notice a huge difference, no matter what car or truck you own, or what exhaust system you go with. If anything you're only gainning maybe 2-4 horses (not worth spending over $300-$700 for a name brand system.) So anyways, just change your factory muffler with a magna or flowmaster for about $100 with installation and you're all good to go.
