Ryan,

It's not worth it to mess with the headers in Cali, due to the regulations. Just go with a CAT Back system. I just installed an aFe system this morning and it took me a grand total of 28 minutes to remove the factory system and install the aFe system. The build quality is great and the sound is more throaty, but not overly loud.

with the short tubes he can keep the cats and be legal in cali. with the new intake you will just get a lot of noise, maybe a little more pull at high rpms.

get one of these

Depends, do you want power or sound to be your primary goal? If power, go with the headers. If sound us your biggest objective right now, go with the CAI. It is simple as that.

headers are aftermarket replacements for the exhaust maniflods. They are the parts bolted directly to the heads on the sides of the engine. They channel the exhaust from each cylinder down to the exhaust pipes

Yeah i guess that pretty much sums it up. I think Ill go with the headers first. Non of these would make me lose low end power would they?

Cold air you could lose a tiny bit, but as far as I am concerned, the headers will more than make up for it on the low end side of things.

I'd go for long tubes. I will be going for long tubes in the future. Just take them off when smog time comes around. Way better then cutting the stock stuff up.

hmm i was thinking about getting shortys with high flow cats. that way it there is a closer effect to the long tubes and i never have to mess with anything once it is done. Also what is the big deal with cutting and welding to the cats? And i also heard the long tubes make you lose some low end power as well.

High flow cats will do nothing if your cats are fine. Most people say they gain power but only because they are replacing a clogged cat with a new one. The big deal is getting the work done. If decide to sell then you can't take them off without damaging the headers. Until I see this documented loss of low end power I don't believe it. Now if you took out all the cats then you will see a loss.

I haven't done it but just by sight it looks like there should be plenty of room. Way more room than Ranger had.
