my understanding on both matters..

'offroad use only' = 'not legal for street use (so be cautious when cops are present or swap it with stock header when smog check comes around)'

the Dealership can void your warranty if they can link any problem you have with the weapon r header, when you send your car in for repairs

 

Thanks for the quick reply. However:

t3chn0rav3rb0y says in that post that the WR race header is not emissions legal, but the street header is. I've been trying to find out definitively one way or the other.

Perhaps it has no O2 sensor bung?

 

this header isn't CARB legal in CA. All the other states i believe is okay. so just the Californians gotta be cautious :-p

 

Both the race header and street header do not carry any kind of CARB number for any state.

 

is this buy still going on?

 

yeah, is it? I'm interested since I'm starting my exhaust stuff now. Got Spoon N1 in the pipeline, thinking about this header!

 

is this still going?
