I'd like to get a 3" DP installed and remove the first catalytic converter thats on the downpipe. Attached are my emissions results from May 06. Everything is wya easily passing except 15mph hydrocarbons, will removing the first cat put me over? I think I can easily pass visual, most places prolly won't notice the 1st cat missing, just whether or not I can pass emissions. How much does the precat really do? Thanks!
