CAI vs. Headers

Hey guys I have a real simple question...Should I go with the AFE stage 2 si CAI or get a pair of shorty headers? Also what kind of performance gains or losses am I looking at with each of them?
Your impute would be greatly appreciated

 

The $25 rebate on that AFE CAI only lasts till the 31st if your gunna go that route

 

Headers?

 

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.

the headers are the only thing that gave me noticable power gains

 

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

Can someone tell me what a header is?

 

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?

 

k awesome. sounds like i will do both of them eventually. now comes the hard part, getting the change

 

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.

 

i beg to differ. didn't notice any loss in torque on the bottem end

 

that makes sense. and what do you mean taking out all the cats? arent there just two?

 

4 total on the 1GR. 2 in the manifolds, 2 in the Y

 

oh i see. i dont plan on replacing my Y's anytime soon so thats not a problem. now im leaning towards the long pipes. the only thing is that i inspected my headers and it looks like itd be hell taking them off and then putting them on again mainly because of the bottom bolts

 

took me 2.5 hours... have a friend too it helps alot

 

how did you guys manage to get the bottom bolts tight? there looks like very little room to put a wrench in there

 

you need small tools and a lot of hand/finger strength. Or you could try and find some specialty tools that twist and bend into tight spaces

It's really not that bad
