Post Will my Strömung Dual-tip affect emissions?

Just wondering if my new exhaust with the midpipe will affect emissions? I'm just deciding whether or not to store my stock exhaust and air intake to reinstall come inspection time.

Also are the inspectors pretty strict in the SF Bay Areaa about exhaust noice levels?

Stromung Exhaust is not CARB certified. The exhaust will change your emissions a little bit, but not enough to make you fail the sniffer test. And most smog techs don't give a rat's ass about the "visual" part as long as the computer says you are clean.They do not demand CARB numbers or climb under your car looking for the stamp.
And as for noise? That's only something that the police care about. Most smog techs will tell you how cool your boxer engine sounds.
In short, in general intake and exhaust are nothing to worry about, it is turbos that can be a problem. But usually Ben Franklin can fix that problem for you as well. **Note: I am in no way encouraging you or others to break the law.** But I love my Stromung!

When I moved to CA from OH, I was a little nervous about the CARB inspection. Turns out that most cars, at least the Jetta I had at the time, have CA legal emissions equipment. There's a sticker on the hood, I think, that says whether or not it has CA emissions equipment.

As far as the Strommung goes, if you can spare the cash for two tests, just see if it will pass with what you have on it now. If it passes, good, if not, just put your original stuff back on, reset the ECU for good measure, and go back in there.

If you ever are in a position to register your car in another state, do it! When I moved there, I left the DMV with a 95 VW registered as an 87 Nissan Sentra, and the wrong VIN. To add more incentive, most other states don't have the ridiculous registration fees that CA has. Have fun.

Thumbs up

Arnie - you definitely don't have anything to worry about. AFIK from '99 on all Subarus are California spec, but only the ones in California have the CA underhood stickers and registered block numbers. In any case, I brought in a non-CA '99 RS and it will do 4 PPM hydrocarbon at idle... failing is 100 PPM or so. The tech said nothing about my single tip Stromung. Even with one stock catalytic converter removed it will still do 17 PPM at idle (I just happen to know this).

If you are going to junk your stock exhaust please contact me first... I think that at least three or four of us in the Bay Area are going to need to keep stock exhausts handy for smog purposes when the MRTs and high-flow cat pipes arrive.

If you bought it in CA, then it should be emissions legal. If you bought it outside of CA, make sure you got the model that is CA legal, if there is one.
