Paul I got the cat delete option on my denali. You don't need to tune it. It should sound much tougher when your done.

You will either need a tune to turn the light off or some MIL eliminators. Or just deal with having the light on.

[MadJack]

good question, if its good there is no point to cutting it off.

He wants an extra half MPG and an extra 1 horsepower.

That will void any warranty if its newer and Kurt last I checked cats are worthless.
