I looked it up on the "internet" and I was a little low. I found numbers from 10 lbs to 13.5 lbs is about equal to a 1 hp increase.

I've seen a ratio that drag racer use as a rule of thumb but I can't find a solid source. I did find several hp calculators based on ETs, trap and weight but not the formulas behind the calculator. Fun to play with regardless.

Just thought I'd put up the weight of my stock exhaust and cat vs my M4 slip on and Arrow cat elim.

Stock can including all mounting hardware
~14.5lbs
Stock cat
~2.59lbs

M4 titanium slip on
~10.9lbs
Arrow cat elim
~.9lbs

When trying to add HP to my car it was always easier to reduce weight, I was told ratio was 10 to 1 regarding weight to HP.
