I received the new exhaust from silent rider yesterday and mounted it on last night. Only took 5 to 10 minutes to put it on. I did a sound check sitting in my carport (it was pouring down rain at the time) prior to putting it on sitting in the drivers seat. On my phone I got a dB of 81 at idle and 98 rev'ed up. After the install still got 81 at idle but only 91 rev'ed up. It could be extra loud because it was in the carport. I will take it out later today and see if the $200.00 I invested is worth it. I should also let you know my Pioneer has the hard top and seems to resonate the sound in the cab a little more than without the top.
