I recently purchased an SSR SR 125 for my daughter and since I live in a residential neighborhood, the loud stock exhaust was a concern so I purchased a quiet exhaust from Vince and it made a big difference. It is not silent but a huge improvement over the sheer volume and open popping sound you get from the stock exhaust. I am an amateur mechanic and it took me about 45 minutes from start to finish to get it buttoned up.
