In a previous thread I asked about exhaust stinger mufflers. A few people have suggested adding an internal stinger. I want to make a few comments and questions about that.
I have done this before,.. but I don't remember having much noise level decrease. Has anyone ever taken DB reduction data on this?
-I should ream out the pipe ID one brass tube size and JB weld into place. Everyone agree on this way of installation?
Some say the tube length should be 10x the diameter. Some say run the tube exactly to the beginning of the convergent cone. (typically the seam) sounds like those might be about exactly the same thing.. thoughts?
- How does this really effect the function of a tuned pipe? now the exhaust flow path is very much changed. seems to me that the gas in the exhaust side is now somewhat compressed. Increasing pipe pressure to the tank.
- How does this flow path change the way the pipe pushes gas back into the engine?
maybe over thinking it.,. it worked well for me in .12 engines.. 45s?
Anyone have experience doing this specifically with the macs 45 pipe?
thanks
