Porter Shorty muffler test. On jackstands and on the road.
This isnt an ad, I didnt get these mufflers for free, Im just telling it like it is when I say these mufflers are BAD ASS. A classic steel pack muffler, thats built like a tank and sounds so so good. I hope you can tell how sweet these sound through all my terrible recording equipment. I am impressed with these mufflers, to say the least.
