    I broke out my torch and hammer and got quite a bit more clearance. We will see how it works out... IMG_2547.JPG

    That's a great video on header bashing, never expected results like that! Seems like you can dent them within reason and have little or no effect on performance!
    If you have good motor mounts your engine will move very little in the exhaust area. The farther you get away from the motor mounts the more movement there will be. For example, your air cleaner will have more movement than your exhaust manifolds.

    I had to do the same thing to mine. Fit was great everywhere except for the damn control arm mount. I ordered mine uncoated as I fully expected some massaging was needed.

    But if you do have do it .you just have to modify just slightly and some time what is causing the problem.Other wise you will have exhaust flow issues.
