Bent Exhaust

Just picked up a '98 XJ. While exploring an oil leak (still looking for the source), I noticed the exhaust pipe has a cave in (looks like a rock hit it or something), and I would guess it's probably squeezing the interior volume of the pipe to 60% capacity for about 2". It's just after the 'y', just before the pipe comes down across the tranny.

Would this affect peformance at all?

Any help is appreciated.. as you can tell I am new at this.

Im pretty sure I know exactly what "dent" your talking about, and If I am correct it came that way from the factory. Not 100% sure why its there but people seem to think its for either back pressure, or clearance of some sort.
