i need some help deciding on wether i want cats or not, i dont get emissions tested, but i also love the sound of the GMPP axle back as it is, if i go ahead and NOT put cats in when i install my LT's, will it be rediculously louder?? i looked for some vids so i could hear one without cats but dint find anything, and anyone ever heard LT's without cats OR has a vid, i would apreciate hearing it
