That price is not all that bad. Figure $80 for the cat plus about $100 to install, the tips are going to be a good $100. The mufflers not sure, they must be around $100 or so each, I will assume series 40? Plus install. Powerlogs are about $120 and the down pipe is about $80. That'*, what, $600 plus the install. Like I said, not bad as long as it'* all welded. I think you will like the sound. There will be a nice deep cabin drone.
