well not strick i am out in nowere florida and i was reading and found out the first two are resinator for reduction of sound so they can go for sure but i head bad and good things about taking the cats off
I think the front two are referred to as precats and do function as a means of reducing emissions (as far as the EPA is concerned, we have 4 cats in OEM form).
It's up to you. High flow cats will not hinder performance for all but about the nastiest of street cars. The stock H-pipe diameter leaves something to be desired though.
I dont know who said that removing the cats (and installing a straight pipe in their place) could cause you to lose power. Some folks kinda get backpressure and exhaust scavenging confused though.............
If considering removing cats, I'd get an O/R pipe.
summit racing will sell a h-pipe for around 110 bucks.bolts right up,gets rid of your cats and is 2.5 in diameter,really frees up your flow and sounds great.i put that and mac pro dumps(muffler)on and you can feel the differance.also sounds great.as long as you dont test emissions your good to go.hope that helps.
