Cobra's popular PowerPro HP is one of the best 2-into-1 pipes ever built for the street. Its beauty comes from a fresh yet traditional design, and it has the kind of modern features no other 2-into-1 pipe has. It shines with triple-chromed, full-length heat shields, and has a unique and stunning collector heat shield so there are no visible welds in this collector area. The megaphone uses exclusive technology inside it to eliminate the chances of the muffler ever turning blue. The PowerPro HP 2-into-1 produces class-leading horsepower from the moment you install it and roll on the throttle. It also uses a 3.75-inch muffler body with a chromed billet aluminum tip.
