Last weekend, I bought a Megan header off another member on here and installed it the following day. Now depending on if I have people in the car or not, I'm getting a rattle from my Apexi GT spec exhaust. The piping is hitting in 2 spots. One is right at the bend by the gas tank, and the other is where the piping bends under the rear suspension. Anyone else had this issue?

Last time I had this problem with my toyomoto ypipe and Greddy Evo. I found out I bent the hell out of it from most likely a speed bump.

I know its hitting, because I've had the car up on a rack to look at it. Also, I just have the car lowered on eibach prokits, and very rarely scrape the end of the muffler. The header repositioned the exhaust, but I'm not sure how exactly I can get it to sit right again.
