If you really want the P's your best bet is to get the headers that are made for them. Some headers will work...but is it worth the trouble? I had stock exhaust when I got the P's so it wasn't a big deal to get new headers. But you can probably sell your set up pretty easily. Since it's only 3 months old it should still be in good shape. I really like the heads. The car pulls really hard down low but it also pulls really hard to the rev-limiter. What ever you decide to do you'll be happy. Just because the car will be sooo much faster. IF you do get the P's make sure you clean them up(Port 'em) it'll be worth it. I wish I had so I'm getting ready to pull the motor apart(again) to port them. Good luck!
