Faster With Or Without The Cat Converter???

[JwMonE99]

I am just wondering becasue I have a 99 V6 and i got the cat taken off when i put up the exahust and i might be putting a cat back on this week so im just wondering if i would loose any power or gain?

[01SOMSS!]

dont know about hp gain but it sure will sound louder

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~NICE~CAR~IS~A~NICE~CAR]

that would sound...........not very pleasant!:(

[silverz28camaro]

put a flowmaster on your car with no cats and keep the stock manifolds

that would sound...........not very pleasant!:(

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.

yeah i thought you ment straight from the headers! lol
but yeah i had the high flow cat and magnaflow cat back on my 01 V6 it actually didint sound to shabby! lol

Reason why I ask is becasue im trying to get rid of a rattleing noise my car makes when it gets to about 3 rpm

[A~NICE~CAR~IS~A~NICE~CAR]

hmmm i dunno if that has anything to do with your cat, but then again V6's usually just sound kinda :sillyme: no offense i had one...:cheers:

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

[Dskeet6]

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