You might expect to see a slight increase in HP but not much with this conversion by it's self. Your need to combine mods like stage 1 & 2 DNA filters fuelling device & open cans to feel any big HP gains.

Did you gut the cans by just removing the catalytic or did you remove the catalytic & baffle them??
