Re: Cat removal? (jmzvet)
The smell.
Get it dyno tuned, pulling the cats will make a significant change in the dynamics at the valve overlap time. The only way to compensate is by editing the PCM and tuning it on a dyno and monitoring the mixture.
For various good and valid reasons, I'm against removing the catalyst on a highway vehicle. If you find youself overhwelmingly horny to do this for some reason, then do it properly.

:iagree: When you add the cost of the parts, and the cost of proper tuning, it's a pretty poor cost/benefit ratio. Add in the grief from your neighbors because of the freekin' NOISE and the added pollution I just don't see it as worthwhile for a street driven car.

:iagree: If you are not an all out track racer, why would you do this? Very little to gain except fines and/or jail time. :conehead Obviously, most people think they won't be caught and don't care about the polution angle, but it is a felony. :yesnod:

Re: Cat removal? (jmzvet)
If I remove the Cats from my 03, install some O2 sims and straight pipes, is there anything else to be concerned with ( other than smog issues )?
There are MANY other ways to go if you are looking for the power and/or sound.. :cheers:
