Cats??
 

I have a few questions. Which should I run stock cats, gut cat or high flow cat? Also the longtube header do I need buy long wire for o2 sensor to bung in?

I would run no cats, and the longtubes usually include some wire to extend the sensors, but mine didnt need to be extended, they fit fine.

With long tubes I did the Magnaflow cats. I don't want to be a gross polluter, just want to go fast on demand.

i personally prefer no cats because its cheaper, especially if your going pacesetter, and i like the smell and the sound. otherwise i would do like trever said and get high flow ones.

LTs = no cats IMO

no cats 4 sure. smell and sound is glorious :)

u wont need wire extended but u will need to splice the connector if u end up finding out u have a couple 02s that are welded in, I did. Other than that u wont need anything but a couple hrs and ear plugs for the drive home if u're taking it to an exhaust shop

VEry funny for ear plugs. I bet will love it anyway.

Allright. I tried look cheap high flow cats but seem still price high? Where is cheaper and good to use. In my locate 30205, Ga will always have emission test.
