I just replaced a set of high dollar, switchable mufflers to a set of IMCO Gattling Gun type. Wow, what a difference. The sound level inside the boat as well as out is at least 50% better if not more. Zero back pressure, no black on the transom and best of all no fouled plugs. The best single improvement I've ever performed on any boat...

Can you post any pictures of what they look like ?Inside and out?



Thanks
Rob

thats a lot of praise for a muffler!

The Spider Boat at Offshore Performance now mufflers such as these. Sweet looking setup.
