Putting the cat back on will make it more quiet than without. Your Jeep may even run a bit better better and get better fuel milage. Not to mention better for passing aircare and better for the air we breathe.

It doesnt sound gooder cause they suck on anything less than a v8.They arent made for 6 cylinders so what ya hear is what ya get.

Flowmasters are designed to run with cats so the volume of noise will not be effected. The reason it is sounding different is bscause you removed your cat. The O2 sensor is slowly getting dirty eventually you will not be able to start your Jeep at all. My advise is to put your cat back on as not only will you fail your aircare on emissions but it is also ilegal in BC to remove them from any vehicle that comes from the factory with one installed.

I punched out the cat and installed a pipe inside the cat. Added on the Flowmaster and it DID make a HP difference. Sounds better than the other cheap crap out there. Seems funny when a newbie asks if I got a small block in my toy.

Put your cadillac converter back in it's better than driving a Jeep.[16][16][16]

If you try to please everybody, nobody will like it.
