Yea ive noticed the buzz at higher rpm's...sounds pretty good i think for the price, i dont know how much more $ im gonna invest into this car though...im thinking about getting a Mach 1...so i think i should just save for mods for that car..

taking the rear cats off and still using the rear O2 sensors will not throw a check engine light as long as the O2's are not further than 12" behind the first cats.
going divorced will make it alittle deeper and alittle louder but your better off removing the rear cats. it will sound Ok like that even though i don't care for MAC's. they will buzz at higher rpm's no way around that with MAC mufflers

So if you take the rear cats out...and keep the rear O2 sensors in place it wont kick any lights on?? and i really dont want to have to change out my MAC cat back exhaust, but fastfall90 said that mac doesnt sound that good with a non-catted setup...anybody else heard a MAC system without cats? and can any muffler shop custom make me a divorced setup? and how is the sound of the exhaust going to change if i go divorced... well lets say for now i leave the cats on. if i just go divorced is my exhaust going to really sound any different? or will i have to do something with the cats for it to make a difference in sound.

yes the car will pass a smog check without the rear cats as long as you keep the rear O2 sensors in place

Would the car still pass emissions with just the front two cats on it?
