So i was chatting with a friend who owns an old diesel van about passing emissions the other day and he said that he usually locks the thottle from fully opening before he takes the car in for inspection.

My question is whether or not it would work for those of us who are running catless by lowering rev limit to 5500 rpms or putting something under the gas pedal to keep it from going full thottle.

 

i doubt it. i think when catless even at idle you can smell the toxicity.. lol

 

lol best thing u can do is find someone to pass u for a little extra $

anyone can tell if u are running catless it smells disgusting

 

Must suck living were you live. Out here as long as you dont have a check engine light on...you pass

 

Standing emissions are 2 step.. ie one at 3,000 and one at 5,000 rpm.. so it wouldn't help you at all either way other than failing you if you can't make it up to that rpm

Not sure how it's done where you are, but I'd imagine they are similar.

 

If your from NY like your profile says then why even bother. NYS does not do emissions inspection for OBD2 cars. You'll fail for the testpipe in some shops just for having it. It doesn't matter how much you lock down the throttle.

 

just put fill your tank 30% with gas, then right before you get there fill it up with isopropyl. It will help ya pass.

 

Hey just register it upnorth or in a part of your state that doesnt do emission testing.

In my state you can even register it upnorth (where there is no emission tests) AND then put down that the vehicle is being housed closer to where i live. Somehow there is a loop hole...since its registered upnorth i never get emission testing, but then i get the convience of getting my registration, plates, stickers, etc sent to my home address and not upnorth since i listed it as the place where the vehicle is "being stored"

 

i have a test pipe and passed emisions in new york, just put a spacer on the o2 sensor after the test pipe, search u will find the exact part sold at most auto stores.

 

When did you do emissions? New York hasn't done emissions testing for a while on OBD2cars. You would actually still fail emissions with the sparkplug fouler mod if it was done.

 

Disgusting...hell no! it smells like an evo! FTW!

 

Lol im running catless but the smell makes me sick

i wont have to worry about inspection for a while

 

just put the stock cat back on and then take it off.

 

I dont think there is a way to hide the toxicity of a catless evo
