When I was younger I had a camaro and I accidentally hit a rock in the middle of the road (I was coming around a bend in the highway when there was a huge rock and not enough time to stop or no where to swirve) so I hit it and it tore up my exhaust pretty badly. A few days later the cat ended up being clogged so I attempted to remove it and put a different exhaust on. It didn't work out too good and I was left with a car I couldn't drive because it was way to loud with open manifolds. If any of you guys are still reading by this point, my friend John and I bought the only muffler that could fit on the end of the 3inch y-pipe. A chevy suburban muffler made by walker. So we crammed that bad boy under there and put a little turn down to the side of the car. HAHAHA It sounded nuts. The funny part was, one day I was driving into my neighborhood and there were these chicks in a car and as I rolled passed them the clamp came loose and the thing fell off right next to them. It was so loud, I had to go back and kick it off to the side of the road and later on, get it when it cooled down. But it was pretty embarrasing when everyone was watching me, lol.
