I just sold my Vantage roadster with windshield and quicksilver. I loved both. the quicksilver is good for 8-10 hp and had great sound at idle through redline. The wind deflector is nice for long drives especially if you have a passenger that you want to talk to. I like the feel of the wind and I had the 700 watt stereo which overcame most sound. Try ebay or call around to dealers that may have one in stock and looking to move it at a discount. 3000 installed is a good price for the exhaust. Good luck.
