Also, I don't think you can eliminate cats with headers and meet the necessary emissions regulations, smell or not, if I'm wrong on this then OEM's could save some $$ and more thoroughly tune engines and meet emissions.

Didn't say there wouldn't be a performance gain. For the price of headers the gain wouldn't be worth the investment. Why increase exhaust flow with multiple chokers down the line. The smell comes from your air fuel ratio being completely screwed up due to improper o2 readings. No I won't pass emissions and I don't have to in my area. The only reason someone would even look for them would be because they're thieves. Gasoline should be illegal too if no cats is. I burn more gas in my mower, weedeater, chainsaws, and welder. Where are those cats. Just information. I can't wait to do mine!
