Right now I have a Greddy exhaust with the AEM wideband in the bung on the exhaust after the test pipe and its working just fine. I will be sending in my datalogs for my new tune and don't want to have to weld and relocate my wideband. Will I be ok to intall my cat after I get my tune? I figure it will just make it run a little rich? What do you guys think? I'm trying to keep the fumes down so I don't harm my kids.

 

really?
