These 3 sound clips show pretty well the changes I have done to the car. The first sound clip is with the car stock except for the muffler removed and the converters gutted out. The car had a pretty harsh sound and was very loud so it didn't last long like that. I added a 16 inch long 3 inch diameter powerstick muffler from classic chambered mufflers. That made it sound much better and I did not modify the exhaust any further once I added that muffler. The last sound clip is after installing the GM ASA camshaft to give the car a real muscle car sound. The car has the perfect sound on the road and idling now. I don't plan on changing it any further. The car actually sounds better in real life than the sound clip shows, everyone loves how it sounds so I won't take a chance on ruining the sound by modifying the exhaust further.
