Great fit and finish . The sound to me is great with th decible reducer in . About halfway between stock exhaust and wide open exhaust .

S&S Grand National 4" Slip-On Mufflers for Harley 2025 M8 Softail

I had S & S pipes on my Ultra, so I knew the quality of S & S pipes was exceptional. I put this Grand National on my, new to me, 2025 HD Heritage. The finish was perfect, install wasn't too bad-as always, it's getting the stock pipe off is a little more work. Installing the new pipe was a breeze. Make sure you orient your exhaust clamp in the same position as it was on the stock pipe so it doesn't hit the frame on the back or the heat shield in the front. It's exactly the sound I was looking for....a little louder at idle and throaty and raspy when you get on it. Shout out to Brian at Eastern Performance. There was a little delay in shipment, but he kept me updated and I always felt like a valued customer. Thanks Brian.
