telluride_tj Posted December 8, 2009 Share Posted December 8, 2009 05 LGT with catless TBE/ E-85 tune. What exactly do I need to do to pass CO emissions? I have all the stock exhaust parts in the garage. Thanks Link to comment Share on other sites More sharing options...
ScoobySTi07 Posted December 8, 2009 Share Posted December 8, 2009 Technically all emissions control equipment must be intact and functioning per state and federal law. Enjoy Boulder. It's one of only five counties in all of Colorado that still requires emissions testing. Besides putting everything back on, the only other thing I can think of is trying to swing a set of collector plates like one bad bg did here http://www.legacygt.com/forums/showthread.php?t=116312 The Ridiculousness is no more But you can have your very own piece of it. **The Ridiculous Part Out.** Link to comment Share on other sites More sharing options...
evak Posted December 8, 2009 Share Posted December 8, 2009 Not sure about the E-85, but my story goes: STi up Invidia catted down X02 cat back Cobb STG 2 91 oct Did not pass Swapped to stock dp, flashed to stock on AP and drove 100 miles or so and passed. This was at the Kipling and C-470ish station in Littleton. Good luck:lol: Link to comment Share on other sites More sharing options...
enthusiast Posted December 8, 2009 Share Posted December 8, 2009 I am running E85 also. All I did was put on my stock DP zeroed out my WGDC table and made sure my cats were nice and hot before I went over there. This is important, do not drive over with your car just warming up. Are you keeping the car now? There is a emissions thread in the Mountain West area also. Good luck. My mod list Link to comment Share on other sites More sharing options...
telluride_tj Posted December 8, 2009 Author Share Posted December 8, 2009 Thanks! No, I'm actually selling the car this week and the new buyer needs answers. I've never had to deal with emissions cause I still have WA plates. Link to comment Share on other sites More sharing options...

Chocoholic005 Posted December 11, 2009 Share Posted December 11, 2009 Usually for Colorado emissions all you really need is a decent cat. I passed with a high flow magnaflow as the only converter in the car. Generally they do not have specific criteria per car to meet in colorado, only for electric/hybrid vehicles. So if you have a decent cat you SHOULD be ok. Link to comment Share on other sites More sharing options...
