so, my truck is a CA truck and it has an air pump and a cat.
anyone have any experience or know how much of this equipment needs to remain for oregon DEQ?

found someone stating this: "'93 and older = no visual for equipment just a tailpipe test "

When I took my '81 in, they just did a tail pipe test.

missions testing is required as follows:
In the Portland area, 1975 and newer model years must be tested (view detailed information (http://www.deq.state.or.us/aq/vip/)).
In the Medford (Rogue Valley) area, vehicles 20 model years old and newer must be tested (http://www.deq.state.or.us/aq/vip/).
In these areas, cars, trucks, vans, motor homes and buses powered by gasoline, alternative fuels (such as propane), and hybrids must be tested.
In these areas, diesel-powered vehicles with a manufacturer's gross weight rating of 8,500 pounds or less must be tested.
If your vehicle meets the above criteria and is new to Oregon, you must have a certificate that the vehicle passed an emissions test before you bring it in to DMV to be registered.

yeah, it's more like Cali where there is the fixed year cut-off, rather than an 'age' limit

I also think that it majorly sucks that they test lightweight diesels

so, back on topic here... if there's no underhood inspection, and you can pass a basic tailpipe test, then anything goes as long as it burns clean, eh? If this is the case, I reallllllllllllllly think I want to do this:

Do it. You're not in California and don't need CARB approval on parts.

the exhaust manifold on this thing is buzzy under the hood and apparently this is a common problem.
if this is the case and it becomes unbearable, the header is first [along with new engine mounts lol]
apparently you can rip out about 90% of what's under the hood if you switch to a weber.
