i know this might be a retarded question...but if you already have a precat'ed downpipe, can you just put on a fed spec downpipe to replace it? im assuming the headers are the same but im just making sure

I'm pretty sure you have to stick with whatever you car is stock. You can't use a fed spec on a cali spec car without heavy modification :\

I may be incorrect though.
what kind of modification are we talking about here

oh boy, sounds like i got myself into quite a mess then...awesome

i would think the only modification necessary would be the o2 sensor...?
Nope they are completely different. The lengths are different and the manis are different. As well as Cali-spec has 4 02's and Fed Spec has 1. I am changing manifolds and having a custom downpipe made. If you bought a fed spec dp you need to return it to get a Cali unless you want to chop the fed spec and make it fit. Good luck.
