I wanted to get a better field of vision with the 20 so here is what I did. All the parts cost less than $110 through Amazon.   Started with a piece of 3" id by 3"od x 12" and cut a 1.5" offset. I found a 3"id resonator pipe that is 3.5 outside, welded a piece of 3.5" od x 48" straight to the outside of the resonator pipe.A little grinding and several coats of high heat paint and it's ready.   It sits directly inline with the air intake pipe.  Ran it tonight and I will say it is not any louder than the stock muffler. Thanks for lookin.

Sounds like a Blues Brothers car to me. Pretty ingenius. I like the resonator idea, tho. ------------- sometimes I walk out to my shop and look around and think "Who's the idiot that owns this place?" |
