Hard to install

As the title says they are hard to install partly because of weak instructions. My biggest issue with the headers is the y pipe did not fit my stock exhaust. Had to go to exhaust shop for them to put in the stock connector which cost another $60. Good stuff but you'd better have lots of tools, patients, time and an exhaust shop handy to get these in with any ease. That being said Ive noticed good power increase and they make the truck sound perfect with stock catback!
