I've never used stepped headers before, but I've heard they are better than standard headers, they make better torque in the lower rpm range. The 3/8" flange is a definate must have, ball and socket collector makes sealing alot better. And the ceramic coating is great, looks better, dissapates heat alot faster. However, the scratch kinda easy and as far as I know, can only be recoated to repair scratches.
