The system I'm looking at has a performance muffler, not straight/open pipe. I'm guessing it can't be any louder than it is now with the entire seam of the factory type muffler blown out. At least the noise will be out the end of the pipe past the rear tire as factory.

I don't want real loud... Some noise is ok
