~$80 for muffler.(super worth it!)Originally Posted by biju
~$250 for install and parts.
Will be another ~$150 to do the piping between the cats and muffler (O2 sensors are there and a flex pipe). +cost of new cats.
I found a little "dad and son" shop with lots of experience - came highly recommended by the local speed shops. I basically told them to take the time and parts to do it right and then give me a bill. I'm quite happy, and I think I got a good job done...
