Yes, it swoops back at a different angle. That's why you need an HO headpipe or have a muffler shop make you one. Muffler shop is better cuz they can make it without the "crush", adding a bit more performance.

Yes, but beware of the proximity of the headpipe to the front driveshaft if you have no lift.
