I made a massive mess out of the Camaro while waiting for parts. Instead of being patient like a normal person, I decided to turn to the rustiest car in the fleet and start taking it apart too. I'm special, but I'm also tired of this thing being noisy and running poorly.
Lucky for me, the manifold side came apart nice and easily. The catalytic converter pipe also slid out of the muffler without a fuss.
The muffler side is acting in a traditional midwest sort of way though. The mid-pipe was only a year or two away from falling right off. I'm shocked that this wasn't incredibly noisy, but the clamp was blocking the massive crack. Maybe this was the buzzing under acceleration noise I've been hunting down forever?
Anyway, separating the catalytic converter from the down-pipe was not simple either. Those bolt heads had rusted down a few mm
Still not pretty but it will work!
Back to the new down-pipe. The Walker unit comes with an air injection plug but it's so long that it nearly touches the other side of the pipe. I just cut it down.
...and installed tight with copper antiseize. I don't really know why I did that instead of just welding it on, but I guess I can install air injection if I ever wanted to for some dumb reason.
Walker also welds in an o2 bung for the degenerates who are removing catalytic converters. I plugged this as well, but I'll want to keep it serviceable in case a future exhaust requires a new bung. Don't mind my buddy's vandalism.
The plan for whenever I decide it's late enough in the day to be grinding metal is to weld an adapter on to the muffler, install a new clamp, and bolt the rest back up! Should be simple. I guess we'll see!
