Hey all, I'm new to the forum and was wondering if anyone could help me with some advice. I have an 05 Volusia VL800, which is Fuel Injected, and wanted to do a custom dual exhaust on my bike. When I took the stock pipes off I realized that there are Catalytic Converters in the mufflers. My question is, "Do I need a Power Commander or ECU Tuner in order to put any other exhaust on?" and if I don't go with a custom job, what brand should I go with to be a a bit louder with a mellow tone. A co-worker of mine has an 02 (Carburated) with Cobra pipes on it and I'm sorry to say it sounded like garbage. I want the bike to have a deep loud tone. Please Help or PM me. Thanks.
