I just installed new headers on mine, Hedman Street Headers 28146 $485. ceramic coated. my old ones were toast. there only 3 tube, center 2 together. went in real nice. I did install a hi-torque mini starter, to have more room just incase have to work on starter.. I really like them.. had the local exhaust shop do the rest of the system. 2.5 inch pipes. with flomaster look a like.. sounds great..
