catless

[proxeyed]

Is it possible for the pt to run without a cat? I think it would be, but I was told it depends on where the o2 sensor is located. I would like to try out the straight pipe idea, but I am curious as to if it is possible. I hear people saying that running a straight pipe improves power and sound. I am aware that it would not be smog legal, but I am thinking about giving it a try.

I wouldn't run a n/a PT without a cat. It would be very loud to run a straight pipe. You can run a straight pipe with a turbo but a n/a engine likes back pressure and a straight pipe could actually make less power. A high flow cat would be an idea. Not only would it be illegal but the fine for not having a cat is like $25,000. You also might think about a cut out. A cut out works by allowing you to use your exhaust system and with a flip of a switch the system is blocked off and your exhaust goes out a straight pipe.

Be careful with those cutouts. I've heard that they are illegal in some states as well. Do your research.

Just put a house cat in the back seat. It would be considered a cat-back. []

dont do it on the street.

1st the Dreaded Drone will make you hate your car.
2nd it is seriously illegal.

leave it in the cat, go with a cat-back system (or just a nice loud replacement for the factory muffler)

I am getting some pretty strong power and good sound from a k&n fipk, Borla header (1-avoid the hedmen's they're crap; 2-make sure you remount the heat shield or else the computer will cook) and a custom cat-back my local speed shop built out of Really Big Pipe.
