Billy Boat Exhaust mufflers for Carrera 2/4 cars are manufactured from high quality T-304 stainless steel, and are completely TIG welded. The muffler has a perforated inner liner packed with a stainless steel mesh, in addition to a series of internal baffles. With this design, we have deadened the sound while allowing the highest possible flow. The single inlet muffler is designed to use the stock heat exchangers and catalytic converter, while the twin inlet is for the Billy Boat Exhaust header system. Either muffler can be ordered in a twin outlet (turbo look) configuration.
With the decrease in exhaust back-pressure, a horsepower increase of 8 to 12 horsepower can be expected, along with better throttle response and acceleration. The muffler only weighs fifteen pounds, eliminating the stock mufflers and reducing 34 lbs. of weight off the rear wheels for improved handling.
SINGLE INTLET – The Billy Boat Exhaust muffler is designed to fit in the stock location on the Carrera 2/4, replacing both the stock rear muffler and the side muffler. A 3 or 4.0 oval exhaust tip vents directly out the rear valance off the car, making for a much more efficient design. The stock band clamps are used to attach at the catalytic converter. A bracket and two stainless center straps are also included.
Stock rear muffler 396 cfm
Stock side muffler 462 cfm
Stock catalytic converter 442 cfm
Billy Boat Exhaust muffler 482 cfm
