In this video I was only testing out my new Gopro suction cup mount on my truck. After realizing that it picked up the exhaust sound pretty well, I decided to show you guys how it sounds, and explain my setup on the 4.3 V6. I did get some wind noise in the video that I tried to get rid of, but at 50mph you cant really avoid that.
Hope you enjoy the video, If you use the suction cup mount it is a good idea to secure it with a rope incase the suction fails.
The setup
-Stock TBI 4.3L V6 in my 1993 S10.
-Old style open element air filter.
-Stock Y pipe
-Jones glass-pack where the factory cat went
-No other mufflers or cats.
-2 1/4" single exhaust pipe that runs all the way back to the bumper
The choppy idle is probably a sign of the engine running rich, not knowing how to deal with the free flowing exhaust. I only get a check engine light on if I let it idle for too long. As far as the glass-pack, I put it on backwards by mistake, and it was not much louder than the stock cat. Before this I just had one cat to muffle the sound, which I really liked, but it decided to fall apart inside and rattle. So with the Jones style glass-pack, it has louvers inside that guide the exhaust to the outside of the muffler where the packing is, so it will make a difference which way you put it on. A Cherry bomb or Thrush style glass-pack just has a straight pipe going through the muffler with cross holes drilled in, so it does not matter what way you put it on, and they are usually louder. Mine did make a whistle noise for a short time but then it went away. Over time the glass-pack will break in and get louder. In my opinion, the 4.3 does not sound good straight piped, with stock manifolds at least, too raspy, with any kind of muffler it will really help the tone, and the longer your exhaust is past the muffler, the more it will pop or wrap when you decelerate. Thanks for reading.
