no cats
Does having no cats , send the pcm into protection mode and richin the fuel mixture.I do know it brings up an engine light,I suppose to show an o2 fault.Ihave an 03 hemi which we took the stock exhaust out and ran dual exhaust with no cats.It really breaths now,Iam in the process of tricking the pcm to thinking it still has cats.does anyone have input on this.
