    Have an AEM wideband I need to install for now, will be replacing everything when the engine comes out in spring but for now just want to use a clamp on bung. Which clamp diameter is needed for stock manifold/mid pipe? I haven’t seen anything definitive but did run across someone saying that the correct size he was told was a little short on the bolts. Who has used one on a stock setup and it fit and which supplier?

    My stock midpipe was 2.5” diameter.

    Thank you for that, was just about to order the clamp and then it just hit me to use one of the rear o2 sensors and just turn those off in Advantage. Problem solved.

    I'm not certain but I think I read somewhere that putting the wideband downstream of the cat would give you in accurate AFR readings.

    It'll still work. I have the same setup (with a DOB supercharger setup) and Lito said the readings are just slightly delayed but will still work fine. No problems with it whatsoever after two years now.

    Do you have cats on your exhaust?

    Yes. The tune I have works fine with my AEM installed after my Cats.

    I'd call that a win then.

    Awesome, good info. I just want to get everything in there now, when I pull the mill out in spring for a build I’ll be redoing exhaust and move it up closer to the collectors then. Right now I’m not gonna let perfect get in the way of “good enough” lol.

    Here's my wideband sensor install. Driver's side. After the CAT. Been working great since initial installation (2 yrs now) without fail.

    I always thought it wouldn't be a good idea after the cat, but then I thought of every dyno run on catted cars (that didn't already have factory widebands) where they stick it in the tailpipe. Maybe they have some algorithm in the dyno software that compensates for that?
