On the OBX, you'll almost certainly need to dimple the #1 tube, because it will rub on the steering linkage. Best to test-fit the headers and dimple it before ceramic coating if possible. Make sure you have plenty of clearance; mine had to be re-adjusted after some drive time. Also, some guys choose to try to shim the motor mounts instead of dimpling the header. It's not always possible to shim it enough to keep it from rubbing the steering linkage (without dimpling) and even if you can keep it from rubbing, you're raising the center of gravity slightly by shimming. Given how heavy the LT-5 is, lifting it - even slightly - can make a difference.

Good luck with the install!
