Go outside and look at your car. Do you know the function of a manifold/header? It's the exhaust that's released from your pistons after the combustion stage in the cylinder. There's 4 because we have 4 cylinder cars. In a Vette for example, there's two manifolds on both sides of the engine block because there's 8 being a V8. People get after market manifolds (which are called headers) that are larger in diameter which allow more air to flow through.

The manifold releases the exhaust(by product of the explosion from your cylinder) through pipes out through your exhaust tip. The other parts, like a DP are ways of breaking down the exhaust system in order to replace specific parts. The DP is connected to the manifold and yes, you HAVE one already, every car does. Hopefully that clears things up a bit.

Its huge.

I bought the straight cut one with mine but didn't end up using it because its too big. It wouldn't be bad on an SS car because they have a different rear bumper, but on a base model the tip is just too big, and it hangs too low to look good.

The SS's use different bumpers, the SS/NA (2.4 non supercharged. NA is naturally aspirated, means it doesn't have a turbo or supercharger) is close to yours, except it has a plastic insert in the middle that extends over the exhaust area. it is about an inch lower than your bumper. The tip fits much better with that style of bumper. The SS/SC (SC is supercharged) has a different bumper, look around and you'll find a lot of pictures, it also hangs down a little lower.

If you already bought the tip try it and see if its your thing. if it is, eh, thats great. (be prepared for a few rice comments) if you haven't bought it, don't.

Its a catback exhaust, which means exactly waht it sounds like.
It replaces the exhaust from the cat converter back. It should bolt right up to the existing cat.
