running catless =[:@]

read the sticky. you gain virtually NOTHING on a civic and you're just augmenting the ****ing environment problem more!!! [:@]

 

i kno, but putting a cat on this would be a b!tch, i'd have to cut both my header and catback, i am looking to sell the header to my sisters BF once i get my turbo. so, if i cut it i'd be hit, he couldnt use it, he is looking to put it right up to his catback, he loves how it sounds. i live in CT, everyone here has a cat, and civics are already ULEV, well atleast the new ones i can say are. so running catless on my car really doesnt make a differnence.

about how long is a intake manifold install? on a 07 SI?? cuz header was a huge job. 3+hours, not like the old SI's, this thing has to go in back of the engine and is rediculous hard to get to.

 

was your header 1 or 2 parts? because if it was 1, that explains why it was so hard

 

was only one part... was a real pain in the you know what....
