You are right about that, the Maxima stinks to high heaven, everytime I follow him, usually I lead though, faster car and all

I'm sorry, but some sort of cat is necessary IMO. If you're driving this car anywhere besides the strip, use one. It really does a lot, and the difference between a hi flow and a tube will only be apparent on cars that are race tuned, and are race cars.

I removed the CAT from my SE & installed a Glasspack instead. This alllowed me to gain low end torque & still keep enough back pressure too. Of course my 92 didn't have two Oxygen sensors though to worry about. An O2 substitute may work to trick the PCM in believing everything is okay back there though.....never tried it myself yet. You still have to put "something" in the CAT'* place though! A straight pipe will not do it. With my setup I noticed more power & a nice rumble sound from the factory Hi-Perf muffler too. Another, alternative is getting a Hi-Flow CAT like this: MagnaFlow Universal Catalytic Converter

I would install a Hi-Flo CAT if I really had to but have to stick with my claims of more Hp and torque without one, no matter if it'* NA or not. None of the other cars I have done it to were blown and they all were able to spin the tires on take off when I removed the CAT as opposed to before when they wouldn't spin a tire....unless I ran in reverse then dropped it into drive....ouch!

The O2 spoof work fine. I tried it first for a few months before removing the CAT just to make sure.

You can't really blame our Club executives for denying the benefits of removing a regulatory device. They would get into big trouble legally and maybe even morally if they didn't.

LOL!
Glad I'm not "restricted" to such then!
But yes, you're right.

Just as a Counterpoint . I can spin the snot out of my tires, and I'm NA with the Cat and pretty good tires....

Ditto.

Someone said that the there is a bad smell from running without a cat, a smell of rotten eggs. Im sorry but thats wrong, the rotten egg smell is the smell you get from most new catalytic converters. Tha't'* why when you drive behind a new car and he is running it hard you have that smell usually, and if your behind an old car that smells like rotten eggs then he probably got a new cat installed. I run without a cat and so does my dad, there is no differnace in smell from before or after removing the cat. What did i notice from removing it? Better fuel economy, a rumble, better low end torque, and more responsive. In place of my cat i have about 4 feet of resonator pipe that is glass packed. Where i am it'* legal to run without cats, no laws saying you need one. However, i will probably soon goto a high flow catalytic converter.
