Will removing my rear cats make my car noticeably louder?

Yes. Removing your cats will make your exhaust noticable louder.

 

I actually have a Crown Vic, I have the four cat setup and I just wanna remove the rear two, fast and cheap.

 

your not gonna see noticable gains by doing that, if you remove 2 then its not gonna pass emissions, so you might as well remove all of them

 

Is it easy to gut the cats if the cat pipes are removed? Can you bang all the stuff out and keep the cats in tact?

 

just cut right before and after them, they will fall right out. but when you get the car inspected your kinda S.O.L. because you cut the cats out.(unless you know somebody, or a chill certified gas station.) can you get your hands on a off road mid pipe for thoes cars??

 

In my opinion..just save up and do it rite. For around(not so sure about vics) $350 you can buy an x-pipe with two high flow cats. Then you can hook up your existing O2 sensors and be done with it the rite way. Offroad x pipes in my opinion sound like ace at higher rpms and I would never have them. They will also lose some torque due to zero back pressure. If you really want to do this though get an electric power drill and attach a long rod into it with a slightly bent end about an inch or two from the end. This will hollow out the inside of the cat. Then just hit it with a real hammer and the pieces will fall out. Do this till you get all of the cat out.-Shane

 

With the new inspections here in New York, they just do a visual and a OBD II scan so with my XCalibrator to shut off the CEL, I should be fine. To have an Off Road Pipe made for my car I have been quoted around $450 from a couple of places and thats just for the Cat pipes from the manifold to the H Pipe. I figured gutting the cats is a much cheaper and effective option.

 

Holy smokes at that price! Let me talk to a few guys in my club that have vics and Marauders..I'll get back to ya-Shane
