OBX Calif Legal?

[RON]

my 1st dyno was with the stock exhaust and air box and i got 252 hp, after the pipes went on, with stock air box i got 284.5 hp, now i have a cai i need to dyno again.....................

Regarding the 1st run.....When you say *Stock exhaust*..did you have a cat back (with/without cat)? Also...did you have the injectors/pump/6lbs? I guess what I'm asking is....was the ONLY change on the second run the OBX set up?
In any case, we will have my results to go up against yours with THREE additional mods: 1) Headers 2) Pump/Injectors 3) 6lbs (vs my 5.5). As far as intake....I have injen short ram, which isn't really any better than your stock air box .

Gotcha...
Not to beat a dead horse ...but....
when you say *only OBX change*...what about the CAT back if you had a factory set up in Dyno 1?

BTW, Damn nice #s ..congrats!

completley stock - headers - y pipe - cat - muffler...............

but as to answer your question, no, your y-pipe will not bolt on to your headers....the design of the headers make them different lengths and dimensions than the stock headers from what I can tell when I installed mine

What about having them welded up to my Y pipe? The OBX is so damn cheap...and I really think they will work BETTER with my pipe. Do you see any problems with doing that...irrespective of what your opinions are on the Y pipes?

I'm not sure exactly what you want to weld up to your y-pipe. You would either have to modify the y-pipe or the headers to get either one to work with the other.
