Agreed. I'm sure the sound is a little different, but when I wrecked my SLE we had to cut the exhaust off to run it and it sounded terrible.

Don't do it, 3800s are not a very good sounding engine.

Straight pipes are terrible. Also decreases performance tremendously because there is virtually no back pressure in the system. I am straight piped, except I have mufflers. And it actually sounds really good.. grumbly at idle.. almost sounds like I have a cam. You can take out the cat, resonator, do a u-bend delete, and get some good sounding mufflers and I bet you'll be surprised at how good it sounds.

I hate the urban myth of back-pressure. You don't want back-pressure. What you want is proper scavenging, which is that the exhaust exiting actually creates a suction in the manifold, pulling the exhaust out of the cylinders. Too much flow, and the exhaust leaves without doing this. Too little flow, and it gets backed up in the manifold, and the cylinder has to work to push the exhaust out.

Same thing.. just another way to describe it haha. Either way, straight piped eats your performance. Feels like you're driving a semi.
