I want to buy TTI 1-7/8'' w2 headers but I don't have the wide spread bolt pattern. I would have to buy the 1-5/8''to 1-3/4'' step header. will I lose power with the smaller tube? TTI recommends the step headers to 550 hp and I have over 650 hp.

Mr P, the max RPM is 7200 I believe with 7200 rpm and your ci.. you would hurt the performance... stay with the size you have now.. replace the flange
