Sup guys I want a new cat back exhaust system. Something that sounds great and most importantly that increases MAXIMUM performance. I want to get the Random tech high flow cat because it bolts up easily. Everyone is saying there exhaust system is the best out there?? I would like to know from real people with real opinions. Should i get 3" or 2.5" ? and yes i plan on getting headers later. Right now im looking just for an awsome cat back to bolt up to the Random Tech cat or am I better off getting SLP welding on high flow cat?
