I paid $30 for mine installed. The shop had also made my custom cat back flowmaster/ no resonator setup, so nothing with the Y-Pipe fit quite right, so they had to add a few pieces and custom make an adaptor to get the Y-pipe to fit right, and I still only paid $30. Oh, and he also "fixed" my cats included in that $30. $240 seems to me to be rediculous, even if the bolts were rusted, as they were on mine. Hope I could maybe help a bit... Peace y'all. -Nick
