Thank you! It does kind of sound like a twin, that's what I love about it. Like Uncle P said, don't waste your money on a full system, you don't need it. Go with a mid pipe instead. I'd go with a set of slip-ons, either Leo or Arrow. I have a set of Leo's, and I absolutely love them. Just go check out YouTube, to see what sounds best to you. I'd send your ECU out to Jet Tunning for a reflash, guess this helps with performance, and is on my next list of mods. http://www.jetttuning.com/that_s_racing/view/1143/ecu_review_from_ken_hill
