I HAVE A NEW FLOW 80 WITH NEW PIPES FROM THE CAT BACK. I BELIEVE I HAVE THE STOCK CAT ON WITH STOCK HEADERS. WHICH HEADERS AND CAT(HIGHFLO?) WILL GIVE ME THE MOST AGRESSIVE SOUND AND YET LET ME PASS THE STUPID EMMISIONS TEST?

I used a catco it sounds great, and is still eco friendly.

 

You have stock headers? To me that seems amazing...but maybe you mean you have the stock manifold? In either case, new headers will surely be an improvement.

 

I'd go with catco or dynomax (I've heard catco fits better)
