I'm not sure what the brand name is but I went to a local shop to get a "full cat back exhaust" price, and I was told it would be around $750 installed. Does this sound right to you guys/gals? I really can't spend that much money on an exhaust system (I am ok with $300-$350), but I do want the full cat back because my stock is all rusted and getting ready to fall apart. Any suggestions will be appreciated. I searched but didn't really find a lot of help on prices.
