i searched this subject and found TOADSTER did this but it wasn't clear if he straight piped it from there on out... (sucks how we have to disclaim our questions to the Search Nazi's) but anyway, if i took out the stock resonator and replaced it with an Edelbrock, or even a MagnaFlow, would it be okay to leave the stock mufflers in the back???
