    21507 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from sound great I put a 3-1/2" pair of these on a 502 and I'm really happy with them. They are very well built and maintain the open header sound but bring down the decibel level quite a bit. The only thing that could make these better for me is a SS version.
