yeah, I'm kicking myself on that. (Headers) I was in one of those situations where I had rust in the U-Bend and the cat was shot, I made a snap decision on the Downpipe. On another note, i was trying to do some troubleshooting today Confirmed the coupler, I replaced the wires with AC Delcos and runs good now but I took it on a quick spin and I noticed that from a Dead Stop when Accelerating I hear/Feel a "clunk" (best way to describe) only from a dead stop and not in reverse (I backed out of the driveway and did not hear it). I am guess maybe the CV axle(s), does not sound like a Wheel bearing also the steering has some play in it and the sound sometimes although faint happens when the I turn the wheel to the right? Either Bearings, Axles or Steering, any help is greatly appreciated!
