I received my Gibson bullets from Dana Marine yesterday as Bob promised. Installed in minutes. Took it out to Lake Pleasent today. The Gibsons really knocked the noise down. They look very nice too. I would not have a problem recommending these mufflers. I have the HP500EFI which is turning a stock 24 pitch at 5000 rpm with 3 people and full tanks. 64.8 GPS MPH (Before Mufflers) Today, which was warmer, seven people, two full coolers, full tanks, got 59.8 GPS MPH at 4900 RPM. So, I really dont think I lost anything. I had a lot more weight. I might go out tomorrow for a while with less weight. I will keep you guys posted.
If you want to get mufflers, I am highly recommending Bob at Dana Marine Products. 951-279-5005.
Thanks Bob,
Mike
