What would make more power on a stock ss/sc

a cold air intake
or
catback exhaust

thanks,

its a toss up but id lean twords the catback

 

nethier are goin to give you any power your goin to notice. now both of them together and a good tune that u would like for a starter

 

are there any cat back kits that are quiet? i had a honda before with a magnaflow cat-back and it was quieter than most others ive heard.
i love how quiet the cobalt is stock and was hoping to keep it like that.
i also heard a ss/sc with a exhaust system (whether it was cat-back or axle-back i donno) but when he took off i could still hear it after it was already 2 blocks down the street.

is it possible to get silincers?

 

get a magnaflow axle back..there nice and quiet..lol..i got one for sale

 

i dont think i would get an axle back just because there is really no gain with them. atleast less than a cat-back and even then there isnt much of a gain.

arent axle-backs basically just for looks?

 

i personally think the gmpp touring is the nicest sounding quieter exhaust around

id go for the intake, cuz power will probly be prett similar either way, but the sound from the sc from the cai is totally worth it, its also alot cheaper to get a cai then a catback, so with the cai, you get more hp/$

 

ya ill probably go with the CAI if the HP gains are similar because its cheaper and also no loud. probably get the cat-back in the future.
