I live in texas and have emissions testing. would i still pass if i delete my mufflers. im pretty sure i would b/c isnt the emissions thing completed by the cats? also would flow/loudness improve and how would it sound overall. its a 5.3L avalanche 1500

 

my truck doesnt have mufflers on it, bought it like that. i think it sounds good not too loud in the cab and doesnt drone unless im luggin and its about to shift, but it is a good bit louder than my friends truck which has a chambered muffler on it

 

louder...flow better.. and wouldn't mess with emissions
