Exhaust Pipe Diameter 273

I had the 40 series on my 318 Duster. Paired with headers, they were pretty loud at the tips. I decided to chop off the tail pipes (just behind the muffler outlet) one day to see what kind of racket I could make. Now, that was some serious noise right there, especially inside. They sounded great once you got on the throttle, but I couldn't hear my sound system anymore...Not really going for performance, just sound.
