Take it to a muffler shop and have them bend pipe rather than buying a
catback kit.  Result is about 1/2 the cost.  I paid $195 installed for
3" pipe and a good muffler.  I don't remember the brand I put on that
truck but it was a name brand.

I just had estimates for my 99 xcab. Dual after converter is about 350.00
but single pipe and out the side is 150.00. This is from Midas.
