High flow -vs- standard is around 10-12 rwhp, standard -vs- none is around 15-18rwhp.

I might be crazy, but 15 - 18 rwhp thats the same if not more than LT headers. I dont think so.

Uh, nope...... they are more restricive than you think, and I forgot to add that's with a tune (check engine light will come on) which helps as well.

Do you recommend adding a mil eliminator if I remove my cats? Providing I don't get a tune right away.
