I Go Wide-Open in My 711ci Twin Turbo Jet Boat! Finnegan’s Garage

This time on Finnegan’s Garage we build a supercar exhaust system for Game Over, my 19-foot long fiberglass jet boat. We hooked up with the dudes from Stainless Header Manufacturing to install a new tip that looks like it came from a Lamborghini. We cut and TIG-welded 4-inch diameter exhaust tubes to connect the Precision Turbos 88mm twin turbos to the new tip and then we went back to lake Allatoona in Georgia to see how she sounded. The noise was glorious! 13:44 Go here to see and hear it. Want more info
