@wintershade I'm assuming you don't have a tune. You didn't get a CEL with the cats? What year is your car? Thanks.

@wintershade - If Santa decides I was a good boy... I am going to install hf cats, no headers, with stock PSE this Christmas. I want to accomplish what you're looking for... some fun/sport exhaust and performance under spirited driving & track days, but no drone and the ability to take a con call in normal mode when cruising at highway speed. I'll let you know what dB I measure in both sport and normal modes if/when I do this.

I have a valved JCR exhaust and race cats. To my pleasure it does not drone and very quiet in Normal mode valves closed....Options are endless.
