Car wont pass inspection, need some suggestions

Ok, so if any of you have seen my threads, you know I've gotten some new pipes in my car. This was to combat the P0402 code. I thought I could just replace the header and all that and all would be good.

This is what I put on:

+ a midpipe

Well I didn't know that that would remove my catalytic converter, nor that it was required for state inspections (I live in VA).

So now my car has a failed inspection and I'm not sure what to do.

Basically from the engine to the resonator all parts are new.

My mechanic says I should just take it to another inspection station (I took it to the dealership because I get free inspections there, and they know my car very well) and they'll probably over look it.

Or I could have the dealership put on a cat for 938$
Or my mechanic could put one on for.... (Idk how much yet)

Kinda backed into a corner here... again...

why dont you just put your stock cat back on for a minute...go get inspected...then put your aftermarket header back on?

thats what all the cali guys do (me included)

i dont see the issue, unless your threw your stock one away, in that case i have one for sale (pm me)

btw, P0402 is EGRC/BPT Valve, that is an failed egr/bpt code, but qr25's dont have an egr...

did you mean P0420? thats the failed cat-code, which would make you want to get a header asap. is that what you meant?

Back to stock. Either that or try to cram 2 cat's in there. My Nismo header + midpipe w/ cat didn't pass by like 30% here in Cali...

Like smokeyV said, use the stock manifold for inspection (assuming you failed the visual), inspect the car, and mount the header after you have the stickers on....

If the test you failed was the OBD-II test due to the P0420 code, the best way to bypass that with the header is to use an O2 spacer (either the "ghetto sim" with the spark plug non-foulers or any of the spacers sold on eBay), or to get an O2 simulator (which is what I did) and wire it to the downstream O2 sensor. Should you find someone to overlook the visual test, it will pass the OBD as long as there's no codes stored in the ECU (regardless of MIL status). The other way to pass would be to place a high-flow cat in your midpipe and relocate the downstream O2 sensor to behind the cat. That way you would pass the visual and the OBD with the header....

If VA does the sniffer test the best bet is back to stock.....but I was just checking the procedures for VA emission inspection and you can get the OBD-II test done without doing the sniffer test (like it's done here in PA) so you can do what I said in the paragraph above....

Just have your main cat flanged in.

I've got a 4-1 header, going to stock midpipe/cat into an Apexi Ws2. I've never had a problem.

You're getting whacked on the visual inspection.

I dunno what part of VA you're in, but if you're in Hampton Roads, I reccomend Oceana Muffler. Any good shop can weld in a cat pretty easily, I would imagine.

Edit* Oh Yeah, and after the cats in, make sure they weld in a bung for your second o2 sensor After the cat. Then plug your second sensor in downstream, with a spacer, and that should clear your code. It's an automatic failure if you've got any SES light.

I meant P0420, sorry. I already have the o2 spacer installed, so no SES light. And I failed a visual inspection. I had my header installed by my mechanic, I'm not sure if I'm capable of swapping them out myself.

Installing a high flow cat will cost 330$. My mechanic said i can put in a universal for around 80+ install

this is because you removed emission components, aka, the stock header w/ cat, and the midpipe w/ cat.

you dont wanna get "another" cat welded on, especially into your header, or you will eventually throw the same code and have the same issue.

just PUT YOUR STOCK HEADER AND MIDPIPE BACK ON, then go get inspected. its easy, it will work, it wont cost you anything, and you can put the new header back on right after.

$80 + install isn't that expensive for a universal cat....

I live in chesapeake, work @ the oceanfront right off 21st st. I think the mechanic still has the parts, so couldn't i just leave my header and have him reinstall the stock midpipe?

one problem, like I said before I DONT THINK I'M CAPABLE OF DOING THAT MYSELF. I don't want to mess up my engine.

He hasn't officially quoted me yet, he was just saying "I believe you can..." so I'm waiting to get a price back from him

Well, no. The parts won't match up. so to speak. He'll probably find it easier to cut a section out of your 4-2-1 system, and weld in the cat. He may be able to use your stock cat...But honestly, I would just buy a new one to save the fabrication trouble.

Or...you could just eat 200 bucks, ditch the system ya got now, buy a 4-1 header, and reinstall everything, except the old manifold (Replaced with the the 4-1). That's probably the easiest course of action. If the bolts are already loose, it'd be a somewhat easy job to bolt up wiht jackstands in 'yer driveway.

But, as I said earlier, Oceana (Right off the original VB boulevard, down at the oceanfront, near NAS) did good work when I had 'em mod up my WS2. (I had 'em shortne it, so it mounted better, without hitting the rear beam.)

no, like the above guy said, they wont match up. best thing to do is have your mechanic put BOTH the stock header and midpipe back on. without both, its likely that you wont pass the visual nor the sniffer test.

in that case, you should do a little more research before doing major exhaust changes like this. it would probably save you a good chunk of money in labor.

I research everything I do with my car very thoroughly. For some reason I misunderstood what would be happening here.

Honestly, your best bet is to find a good walk through, and learn to do it yourself. It's preferable to have at least 1 buddy for the belt tensioner, but otherwise it can be done in a few hours as a 1 man job. I priced it out before hand, $300 labor to swap it one way ($600 total) every 2 years to pass smog. This is/was a great motivator to learn to do it myself.

Personally, the only thing that I sweat is breaking a block stud in a bad way where I can't grab it to wrench it out. This has been less of a big deal for me as I have a second car to get around in should something happen.
