Just talked to 5 muffler shops and they say that the reason the things will blow out is because people dont retighten them down after the heat cycle. Kind of like a head gasket. That and cheap headers with thin flanges..
Driver side is done. The pass side is in but its just hanging. We are going to finish it Saturday. The weather has gone to crap so no hurry. Here is a view of the driver side.
Yeah, the bung for your heated O2 sensor. :nonod: If you're serious about getting the motor tuned out right, the collector, and heated is the only reliable way to give the ECM a feel for what the motor's doing.
I used the 7th cylinder location on my 383 and the system couldn't get proper fuel trim, nor would it go open loop at WOT.
Several factors come into play. If the ECM isn't seeing what it likes from the O2 sensor, it won't go open loop. I've seen several (more than 2, less than 6) people who've had the problem, and it was solved by going to a heated O2 sensor that could see the whole bank of pistons.
