Since my hookup on a Greddy system fell through, I'm looking for something else. I've got about $200 to spend. Here's my options I'm considering above. Vote on what you think is best and sounds nicest. I've been really impressed with the Magnaflow sound. Prices above include shipping. My catback is about $75 in town with 2 1/4" piping.
