Catback Exhaust systems are designed to completely replace everything from your cats all the way back to your exhaust tips. Traditionally, if you are planning on upgrading your entire exhaust system, you will also need headers and downpipes.
BMW’s move from the S85 V10 to the S63 twin-turbo V8 brought big gains in efficiency and speed, but the factory exhaust left the soundtrack behind. The Valvetronic Designs Valved Exhaust System restores the drama, delivering a sharper, more engaging tone with genuine GT composure when you want it. Connecting to OEM or aftermarket downpipes, this system runs 3.0 inches from inlet to outlet and features a large X-pipe crossover for superior scavenging and response. Exhaust flow then passes through our valved mufflers, exiting via your choice of premium tips. A vacuum-actuated valve system with an included controller ties into the factory harness for full, on-demand sound control.
