11 GT high flow cats
I do not want to void my warranty... If I get HI flow cats, will I pass emissions, will it throw the famous bank code? No tuner and no plan for one anytime soon. Currently have roush axle backs and want it a little louder
THanks for the input.....

he did mention he's just looking for more volume/sound. imo, if you replace the overaxle pipes you'll get the sound increase you are looking for. this is why I did a catback instead of an axle back.
