I have a 07 DX and I want to put on some pipes to make it sound more like a harley. Now, I know when it came to some sportbikes that I used to have putting on a full system exhaust vs. a slip on exhaust system would not yield much more hp gains if any over stock. Sometimes you could get as much power out of a slip on system rather than dump the extra money into a full exhaust system. Is this the same case with the VROD, or will I benefit more from putting on the full systems? Not really looking for overall hp but I am just curious if the V-Twin will respond the same as the sportbikes or not.
