My just installed Rinehart's for the Scout are loud. Too loud, almost, even with my full face helmet on. The Manufacture's Rep told me yesterday that the 4" pipe for the Chief is quieter than the 3 1/2" pipe on the Scout. Feedback to Rinehart on the Scout's muffler: 80% are happy, 10% think they are too loud, and 10% think they are not loud enough.

Shawn, a manager at Rinehart also told me the end caps could be removed and the baffle wrapped with fiberglass packing made for mufflers and then secured tightly with safety wire before reinstalling the baffle to lower the sound level. This procedure is found on YouTube and Google. He also shared with me that red thread locker was used on the end cap screws and said some heat would help in their removal.

It was a big shock for me going from whisper quiet OEM to aftermarket. I will wait a bit before attempting any modifications. Overall, I am very pleased with the quality of the mufflers and the genuine help from customer service at Rinehart. The Scout's motor runs very well with these racing mufflers and the performance seems strong

For background, I got to hear a set Rinehart's on a Chief at my dealer and they were not too loud with a deep rumble. Sounded great to me! The Harley crowd seems to really like them too. My dealer just got his first two sets of Rinehart's in for the Scout and I bought a set. My dealer had never heard the sound of these on a Scout yet. We both installed them over last weekend and boy are they louder than the Chief.

Ordered Acousta-Fill Exhaust Silencer Packing from the UK about 2 weeks ago and installed it today. It now has the sound level of Rinehart's on a chief. My guess is a 30 to 50 percent reduction in volume. It gets almost quiet when cruising, but crack the throttle and you get a serious bark. Love it now. Was able to install the Acousta-Fill blanket without removing the mufflers or the baffles

, just the end caps. The info sheet on this sound packing says it expands to fill the void once exposed to heat.

Update #2. After riding awhile, I noticed the mufflers were again getting louder. Removed the end caps again and stuffed a second sheet (400 mm / 16") of Acousta-Fil into the space between the straight-thru baffle and the muffler's outer wall. Really packed it in tight using a long screwdriver. I had earlier tried to remove the baffles but could not seem to get them to break free. So I removed the mufflers and stood them vertically to aid in packing. Sound great to me now. Whew!

Did this Acousta=fil install stand the test of time? I also have the Rineharts on my Scout and it is way too loud for my tastes.

I was wondering the same thing. I just installed Rinehart’s on my scout and at 70mph I can’t take the noise. Even with a full helmet and ear plugs it’s too loud for me. I am looking into packing the baffles but trying to decide what packing is best.

I'm kind of glad I went with the TAB longs with the 1.75" baffles. Not extremely loud but loud enough.

Added packing to the Rineharts today. It definitely helped the sound a lot. I took it out for a short ride and it seems like it didn't change the sound too much at idle but its a lot better at speed.

I just finished installing Rineharts on my 2020 Scout. I dont know if it's because it's a little late at night and the neighborhood is extremely quiet, but these pipes are too loud for my taste. My goal was to be able to be heard in traffic, (which these definitely do the job) but not this loud. I have to admit that they sound great though. :) I'll leave them on for a while to see if I get used to them. I'll also try the packing as mentioned in this thread. Any tips?

As I mentioned earlier I found the Rinehart pipes way too loud. I packed them and it helped and it seems to be getting a little better over time. I have about 700 miles with the packing and I think I will probably leave them on. I used the drag specialties packing kit . One kit did both pipes as I was able to peel the packing apart and make two pieces. It’s too thick the way it comes. Not sure where your located but I have two extra kits if your interested send me a pm and we can check on shipping cost and see if we can work something out.

Yea, they had these on one of the showroom bikes. It was WAY too loud! It completely debunked the idea without having to even think.

If I would have had a chance to hear the Rinehart pipes first I never would have purchased them. Packing them helps and they are getting better. Not sure why but maybe the packing is settled or burned in. I did have my hearing checked a couple weeks ago and it came back good so I’m not going deaf.

Not yet... did you try drilling out one or both baffels in the stock pipes? I just did the two rears and it was more then enough for me.

Update: Took a day ride yesterday up the WA coast (14 hours). Picked up a Schuberth CP3 Lite and Cardo Freedom 4+. Reviews of the Schuberth said it was pretty quiet, and I thought having that and music would help with the exhaust. Nope. I can hear the music just fine, but the pipes are still pretty loud in the background. Ringing in my ears at every stop and also when I finally got home. I can at least stand the noise on short trips around town now. Again, I love the tone of these things. My background, if you look up my screen name, is from when I was a Combat Engineer in the Army. I handled a lot of explosives in my career, and was also blown up a few times while I was deployed. I also have two energetic boys, 8 and 5. So I'm used to loud things.

If I add the wraps to the baffles, is there a way to take them out to do this, or "stuffing it in" the only way? Thanks all!
