Default New Bay Area WRX needs CA smog help

I just sold my WRX to a San Jose noob. He wants to hide the 300whp performance from his wife so he asked me to fix the catless exhaust before I ship the car. What do you guys suggest?

The current setup is a Helix DP and Borla XR-1. Nice rumble . . . too loud, though.

1) Random Technology DP/mid (one cat) + Borla
2) RT dp/mid (two cats) + Borla
3) Turbo XS dp (cat)/midpipe + Borla
4) Turbo XS stealthback + stock WRX

Just swap for a Helix catted exhaust. then get a greddy Evo2 or Borla Hush catback. Problem solved. (However, neither that option nor any other non-stock downpipe combo will pass smog. Totally seperate issue.)

Dude, that was like no help! The goal is to pass CA smog. Are you telling me the only option is to put the stock dp, mid, and catback on?

Yes, you have to have a completely stock downpipe (catback is okay) intake, and technically uppipe, but you'll probably get away with one of those at a regular smog check. Basically, NOTHING is smog legal in CA without a CARB E.O. # except for catback exhausts.

And I was helping with the "wife can't know it's fast" bit. There is no help for smog.

Hmm, so Carsound/Magnaflow are selling CARB-certified replacement cats. Can I just weld one of those suckers in? I don't necessarily care about legal, per se. I'm looking for something that will pass the sniffer and a "friendly" visual inspection without drama.

I don't want this dude to get beat down by his wife. My wife is still kicking my arse for buying it 4 months ago.

They aren't legal on cars that are still covered by the Federal/California emissions Equipment warranty. Pretty much every WRX still is. I believe it's 7 years/90,000 miles or something crazy like that in CA. Besides, you only need hte stock stuff in during the test. A good catted downpipe will often pass the not-so-friendly "roadside visual."

The federal rules are 5 years or 50,000 miles. But there's two other categories; failed cats or "missing cats." I may give a visit to CA DMV/DOT/CARB. Clearly, this car is "missing" cats so as long as the replacement(s) do the job . . . maybe they don't care if it's stock.

You will need a letter from a smog shop stating that the original cats were damaged in order to legally replace them with aftermarket ones. If you want to use an aftermarket catted downpipe you need to find one that looks stock so it will pass the visual inspection, or have some heat shields welded on to it at a muffler shop.

Intake will only pass if it has a CARB E.O. number, I think most intakes do and a tune shouldnt be a problem, unless it is a piggyback comuter, then it might be.

yes intake is a CARB item. No EO number no cigar.
Cat back is not a CARB item. It does not affect emissions.

It is very hard to pass an emissions modified vehicle in CA.
A reflash maybe but anything else is hard.

Only sure way is to put the car back to stock pass smog then re-install everything.
Not the most efficient way.

Technically the seller is responsible to smog the car. But since you are in NC that makes it a bit hard/impossible.

He is going to have to smog the car to register it. There is no other way.
The damaged cats and all that stuff needs certification and paperwork from a smog facility. Don't forget emissions equipment is federaly mandated so a letter from a NC smog facility will not do much of a help in CA. Either way the buyer should investigate further. He may have to take the car to the state referee if it has aftermarket catalytic converters. What would happen there is open for suggestion.

By the way you may want to post to the I Club in the BAIC forum. People will be more knowledgable.

Cheers and good luck.

Nick

is the sale complete? Did you already smog the car for the seller or what?

I heard that soon in Cali the seller won't be responsible for smogging the vehicle prior to sale...not sure when that is going into effect though

It's got to be smogged one way or another before he gets registration and title.

Default smog

How about getting one of these downpipes + a big aftermarket heat shield to cover up the top portion of the downpipe.

Might give a stock appearance. Also, remove the aftermarket intake and put the oem intake back in.

You may get away with some shenanigans at a regular smog check station, but a referee is smarter than all of us. If it goes that far, it better be stock.

does it have to go to a smog only, or can it be any smog station, because I know the guy at the shell station here doesn't visually inspect ****. He just uses the exhaust probe and gives it to you.

The DMV will tell you. Probably not a check-only station, that's usually for renewals.

info such as above should be pm'ed or it won't be valid much longer.

As to the 300hp - too bad you have to change it to sell it. 300 is a good number.
