[email protected] 0 Report post Posted December 21, 2009 Awesome article. I have an obsession with stock oem exhaust so this is interesting to read. I ran RS4 Audi mufflers on my soarer a while back, they were worth every cent with the Vacuum valves and stainless construction. Quote Share this post Link to post Share on other sites
