I could be wrong, but those exhausts which build backpressure to increase torque are designed for N/A or supercharged vehicles and would probably be detrimental on a turbocharged car. Power in turbocharged cars comes from boost, which is created when the turbine is spooled up from exhaust gasses. If the exhaust gasses don't have anywhere to go after they exit the turbine (because of backpressure), then they are slowed down and it takes longer for the turbo to spool up. Hence, performance exhausts for turbochargers are designed to reduce backpressure as much as possible.

On this subject, can anyone explain to me why backpressure increases torque in N/A cars?
