exhaust questions

ok i am wanting to upgrade my entire exhaust and need to know if i should go long tube headers or shorty headers which is best plus also i need to know about the cats and what exactly it is called and where i can get them to bypass the o2 sensors to get rid of the cats

Long tubes if you can make them fit. Do a sereach, its been talked about before.

Long tubes are best but EQUAL LENGTH SHORTY HEADERS are almost as good, and easier to install. You can also go with unequal length headers but they're not as good as the equal length but are very easy to install. You DO NOT HAVE TO GET RID OF THE 02 SENSORS TO GET RID OF THE CATS! You can get H-pipes or X-pipes with out the cats (known as off-road pipes) and still use you 02 sensors. Besides, if you do not have o2 sensors your check engine light would come on.
