Have an 06 Si and looking for headers but also need to be smog compliant. I'll run a defouler on the rear O2 but I'm curious if anyone has passed a smog test with aftermarket headers, defouler and high flow cat.

I'm in Nevada and we have yearly smog checks; replacing the stock manifold every year would be annoying.

My budget is $1500 for headers.

As long as you have no CEL and they don't look under the car, you will pass. This is the case if they only do an OBD test.

So far no visual inspections during smog tests.
