dart headers

I would spend the extra money on TTI's. Just installed Doug's D453 on my Demon and would not reccomend them to my worst enemy.
Poor fit and finish. Ugly, weak looking welds. Even the bolt holes in the flanges were off.
Lots of modifying and fabricating to get them to fit decently.

I've done some pretty rough header intalls over the years, but these were by far the worst.

This is just my own experrience. Guys love 'em. Maybe quality control was on vacation the day mine were made.
