    Forget about horse power for your car. just drive it until you can upgrade to an LSX vehicle.

    I'd suggest maybe a cutout instead.

    A cutout after the cat will sound better than with no cats. If anything just get a high flow cat with a magnaflow. I think pacesetter makes some headers for a v6.

    Yea i already fixed the problem, instead of putting up a converter back on and instead of the test tube I put up something called a turbo tube. I wasnt getting enough backpressure thats why it was making that rattleing sound and the turbo tube gave me backpressure. But it made me car quieter what can i do to make it a little bit louder

    isnt backpressure controlled by the size of the exhaust valves?????? im confused, i see cars at the strip with open headers all the time
