My favorites weren't on there......TL type S exhaust for people who don't like loud obnoxious tones......Comptechs, and of course supersprints. I have experience with the TL-S exhaust, I love it, I just don't like loud fart pipes. The comptechs are great, but they are pretty expensive and even a little too loud for me still. Supersprints are the best you can get, but they come in at around $1000 or so, give or take a few. I've seen them on a few Av6s and they look/sound incredible.
