Question Question about Cobb Catted Downpipe

Does anyone have it? If so, does it pass emissions in our lovely Northern VA?

I was curious because I wanted to know if it was worth the extra money to make my future downpipe purchase street legal (and semi-environmentally friendly). To be perfectly honest, I'm more than willing to put down the extra money for their catted downpipe, even if does produce less horsepower and but its got to be street legal.

Thanks!

Oh yeah, just seeing if that black subie that looked remarkably like mine (but with a spoiler!) posts here. We talked in Reston/Herndon, at the light where West Ox becomes Reston PKWY. nice car sir, and goodluck with the Prodrive Springs/other handling mods!

I had one. I had a CEL with it. I haven't heard of anyone passing/not passing emissions but you will want to have some kind of CEL defeat to even have a chance.

From what I understand, you should be good. The cat in the uppipe and midpipe should be enough to pass emmissions; a high flow cat in the downpipe just makes it that much sweeter.

Do a search for the mechanical CEL defeat. Use the keywords "Help!" and "CEL fix". It's basically a spark plug extension that costs $2.99 at any auto parts store that you use on your rear O2 sensor. Actually, now that I have said that I don't know if you're going to install a midpipe or not, or if you even need that for just a downpipe.

I'll say this much: I have the stock uppipe, catless downpipe, and high flow midpipe on my car (as part of a full TurboXS TBE). I used the fix as described above, and I got a CEL within 300 miles that lasted about a day. After that, it went away and hasn't come back for thousands of miles.

^ the cobb dp goes all the way to the catback...there is no "midpipe" he will only have 2 cats if he hasn't replaced his up pipe. Get rid of 1st cat and get the catted dp....front cat is for start up emissions only....just drive the car hard to get your DP cat at operating temp and then get the sniffer and you will be fine. Lots of people have the 1 cat setup and no emission problems.

Yes that's good advice...but. Lots of people have the 1 cat setup and no emissions problems, and lots of people have a 1 cat setup and can't pass emissions. I still haven't seen any hard data about the Cobb, so you might be the guinea pig.

We recently did the mechanical CEL fix on Shannon's wagon and she still has a CEL, but now it goes on and off more often. She needs to get it pulled so we can make sure it's the rear 02 CEL.

thank you very much for the info! I think when I'm ready for stage 2, I'll get the catted downpipe. Its worth the chance of it working, especially with the knowledge about warming up your pipes a lot before testing.

Wait a minute, aren't you using an AccessPORT? Stage 2 takes the CELs away. I never had one until after I uninstalled my AP.

i ran w/ it for about a month or alittle longer with just a turboback...you're right the AP does defeat the cels. Maybe i didn't run w/ it long enough to detect any problems i duno.

not tryign to call you out or anything, maybe i didn't have it on long enough to detect problems
