Welcome to a revelation in supercharged V6 sound. Our new valved setup for the B8 / B8.5 platform delivers incredible sound throughout all rev ranges and allows for the ultimate flexibility. Constructed of T304 Stainless Steel, this system runs 2.5 inches all the way back to the tips. Utilizing our high pitch x pipe technology this system delivers a high pitch wail unfamiliar to the platform before. Low-end rawness combined with the high pitch tone provides the driver with the ultimate sound experience for the platform. It is time for you to take your S4 / S5 to the next level.
