So the cut-outs don't affect a/f ratio in a bad way when their opened? I guess what I'm trying to say is if I had one put in before my Flowmaster on my stock "dual" exhaust it wouldn't affect anything negatively?

I went to the track yesterday to test my shorty headers/stock cat setup. i figured out that my truck ran better with the cutouts open. 13.9 closed/13.8 open and 12.6's on a 100 shot... so, unless you have lt's, cutouts DO help performancewise..

in your case it will definitely help..because flows don't flow well so it will compliment...
