Installing a new Cat-back exhaust

For some time now, my CJ's exhaust system had been rusted through. It had gotten so bad that new Rancho shock in the rear was black from the smoke that it took on a daily basis. Virginia's state inspection finally convinced me to replace it (more accurately, the rejection sticker did the job). Here are the steps I went through to install my new exhaust system (including audio of the finished product).


Audio files

I had thought about using new stainless steel setup, but I could never get an accurate description of the sound that it would produce. I decided to make recordings of the before and after sounds so that everyone else could check them out. I used an IBM thinkpad's built-in microphone, and sat the laptop next to the driver's side rear tire. I you can send in recordings of your exhaust, please forward them to the message board.


Stock system (with hole in muffler)
This is the original system. Although it sounds beefy, it was really about as loud as not having a muffler at all.


New Walker muffler
You can definitely tell the difference between the two mufflers. Now, I can carry on a conversation with my passengers.
