My headers are almost as quiet as stock at idel. Once it gets about 1600rpm they get louder than they would be with a muffler or catback. They are also lounder at WOT.

But you probably loose some sound quality also ( or at least I did) you can hear a lot more noise up front and they just dont sound as smooth as stock headers.

For the egr blockoff, you can buy a block off kit or just get a small piece of 3/16 or 1/4 inch flat steel, then mark your holes, drill them, then cut out where you need to.

LTs really can make that much of a difference even with a 50 series? Cuz I kinda wanna keep my cats.. unless I can get em deleted outta the PCM with my tune with an HP Tuners. But I will either run true dual.. maybe a 40 or straight pipe still, but will the headers really make that much of a noticeable difference?
