Exhaust / Cat removal
Now that the car is in the garage, it's time to start pulling things apart to replace the gutted cats. Here are a few pics from under the car. Pipes are rusty, and the no-name mufflers and x-pipe are all welded together, and dump right in front of the rear axle. This was done by the original owner, as it was this way when we first bought the car back in 2004. Although I didnt realize it was all welded together.
Also noticed that the rear end cover is leaking and will need some attention at some point.
I was able to get all the O2 sensors unplugged, except for the forward driver's side. My hands were just too big to fit between the trans tunnel and the trans. i was able to pull the wiring harness away from it's clip, so there is enough play that when I ultimately drop the cats i can unplug it. I was able to get three of the 4 cats-to-exhaust manifold bolts removed, but one is blocked by the starter. By the time I got to that point, I needed to stop and get ready for dinner plans.
Since the O2 sensors are who knows how many years old, ordered some NTK replacements from Rock Auto. Those will go in with the new cat pipes. Since the mufflers are welded to the old cats, the car will be unmuffled until I order the cat-back exhaust pieces. Looking at going with Borla. I've had Borlas on my '01 Mustang GT, '06 Mustang GT, and my '06 Magnum SRT8. I love the sound. Unless one of you wants to convince me for something different.
Here are a couple shots of the factory rear pipes. They were left in place as decoys. They were cut off just before the hanger behind the rear axle.
