I decided to give one of the 300 dollar rs4 exhausts on eBay a try. I'll update after I've got some actual ride time on it. So far it looks and sounds identical to the 650 dollar setups. Not really sure what the deal is. Shipped directly from Thailand to NJ in less than a week. Bike also has the 550 performance ecu.
