Has any one used the Stainless Works perforated louvered core mufflers? What is the noise level of them and what do you think about the sound?
I used the Stainless Works 2" U bend kit with matching mufflers for my exhaust. I'm pleased with the sound, pretty quiet at idle and low speeds, but has a nice "bark" when I nail the throttle. At mid range cruising there is very little drone. After 28,000 miles I haven't noticed any change in the tone. All in all, I'm happy with my choice.
If you are referring to the bullet shape muffler with the straight through perforated core baffle- nice sound at idle, but they get really loud on acceleration.
Never-rust not too loud to my ears. Wouldn’t mind if they were a little louder out the back of my coupe!
You can always add a auger. I had to with a 70 series muffler and then before each tip. Speedway sells them..
