Well Toda sell both xforce and Toda
im sure that if the todas didnt make great gains for the price you would get ppl complaing and they wouldnt sell..as is not the case.

Toda headers have been proven great gains on many dynos
i will be testing this also with a comparision before and after and i will get back to you

to be honest with the xforce headers i gained 1KW same dyno different day im sure the old saying goes you get what you pay for

anyway not baggin xforce they are a great header....but there are better
