I had it on my '04 for 3 weeks. My sound clip may be in that other thread... not sure. Personally, I didn't like it. It sounded awesome at WOT but since I'm a rather non-aggressive driver, I rarely heard it at WOT. Under normal driving conditions, it gives an exotic sound, similar to a Ferrari. I was looking for Nascar, which I achieved by having the resonators removed and glass pack muffler installed. I can't tell you about the ease of installation since I had a muffler shop put the Borla on for me. But he didn't mention any problems. Incidentally, I still have the Borla if you decide to go that route and want a great deal on a very slightly used system. PM me and let me know.
