My HDK install thread.

You did! 383<416. :oops:

My 499 has much better headers (custom made) than the Proparts I bought for the Mega/440-1 540. The Proparts simply did not fit and I am reluctant to dump another $900+ into TTI factory made 440-218 tubes, but probably will. A HDK coil over kit makes more space by dumping the torsion bars and is required per TTi. I have recessed the side bolt on the upper shock mount inner fender hole to help clear the #4 down tube. Oh BTW, trying to fit 2 1'8 step headers in to 3 1/2 collectors.

did you make them or a custom company build ?
