If there is not visual inspection under the hood, it'll pass.

O2 sensors bungs are normally welded onto the downpipe, so you keep the O2 sensor.

And FCD and requisite upgrade fuel pump are highly recomended at this stage.

it's a downpipe, not a straight pipe

So long as you have 1 cat on there

 

what kinda fuel pump do you suggest?

 

No emissions here and lovin it... down pipe, presilencer, mufflers
