I've not heard much about them.

 

I had a Bosal muffler back in 96. I think their other name is Brospeed. The sound was a deep low tone. Quality wise, it never rusted and yes, I still have this mufler but it's now passed down to my lil bro. Still sounds like new.

 

well the acura dealership sells factory replacement bosal exhausts as a cheaper option. these ones don't last as long, but there is nothing wrong with them.
