Will putting on performance cats make my 05 dodge ram with the 4.7L sound better? louder? Performance gains? If any, which brand of after market cats do you prefer? I all ready have flowmaster 40 series delta flow and a CAI which can be heard and seen at http://video.google.com/videoplay?docid=7036001007954263126

 

Yes high flow cats will give you a little louder sound. I had a catco high flow cat on my last truck and it gave it a little deeper rumble. I was very happy with it.

 

I will check them out hanson. Anyone else?

 

i doubt you'll see to much of a gain as your not making massive amounts of power. im sure it will be something you might notice since you drive the truck every day but id say get a new cam in that thing.

 

yeah dean but i havnt found on for an 2005 4.7L V8
