So I'm on the fence about two things. ZZPerformance intake v. K&N intake. also ZZPerformance catback exhaust v. Borla catback exhaust. I'm leaning heavily towards the Borla kit because Chevy offers it and can install without voiding any warranties, my judgment can be swayed. But with the intake kits what is better. I'm not concerned with price. I'm more concerned with power and weight. Anyone know how much a ZZPerformance intake weighs?
