Did you see Shawnski's there? I just did a quick look through and didn't find one.Not sure if you are aware or not but there's a thread on here dedicated to exhaust sound. You might find your answer here.
Below is a video collection of custom exhaust builds by member of this forum and current and future after market systems. Feel free to add you custom exhaust video and please include any details about your exhaust design including pipe size, mufflers use, resonators used and part numbers...www.fusionsportforums.com
