Sure.....it is ok....the generic X cannot be too costly but considering mufflers too I guess at least half of that is parts then $100-$150 labor is fair.....in my books.
If cheapest price possible is what you're going for, then that's a good price. I'd recommend doing a whole catback though (bigger piping) in case you plan on supercharging it later.
