Right now there is a brand new Racing Beat cat-back exhaust system listed on eBay for $455 with free shipping. http://cgi.ebay.com/ebaymotors/Racin...13675968QQrdZ1. They have systems available for both the sedans and P5s. I bought my system from this vendor and they are great to deal with, all the things you want from eBay. It's a great system, quiet at idle with a great note under acceleration. Looks sharp too. Just wanted to share this in case someone is looking for a good system for not a lot of money.
