I'm not sure which LTs to go for because my searching has shown me that there are several brands out there that are damn nice. I'm wondering about the new Kooks headers that are stepped from 1 3/4" to 1 7/8". Will these $900 headers really perform that much better than the $400 1 3/4" Pacesetter LTs? What I really need to know is if the performance gains would be worth the extra $500. Thanks,
