These exhaust kits are designed for people who take pride in creating their own custom exhaust. They allow the installer to custom-tailor these exhausts to fit vehicles with non-OEM aftermarket headers. They're made from extra-long, 16-gauge aluminized steel for lasting durability, and the tailpipes exit out the sides. All necessary hardware and instructions are included for a complete installation. Mufflers are not included.

Great kit for the price. Had to modify one of the angles on the drivers side head pipe. And expand both the ends to fit my collectors but I also used Summit Racing headers so... Only other thing was the tail pipes aren't bent to the same angle so there is a little difference there. All in all, considering the price there is no reason to complain. I would use this kit again, no doubt in my mind. ...read more
