06 Suzuki GS500F Stock and D&D carbon exhaust compare

Here's a comparison of a stock exhaust and a D&D carbon slip-on exhaust on a 2006 Suzuki GS500F. Initial rev about 3,000rpm then going to about 8,500rpm. Basically a remove-and-bolt on project. No re-jetting has been done and everything else is stock (headers, air filter, etc). The D&D carbon exhaust has been shortened to around 15". This clip was taken by a Canon Powershot SD1000.
