Under the "Opinion" header: Why?
Spot on! I guess Ive aged also and the places we go to up in the hills dont wanna wake up everyone.......I've used GPR slip-ons on a few of my motorcycles (Ducatis). They are well constructed, usually comes with various baffles, and for the one's I chose did not require a remap of the ECU (verified by the Ducati shop). I've also used different brands of slip-ons on various other bikes; Akrapovic, Arrow, Yoshimura and probably a couple others (30+ years of riding).
With all that said, I don't have a slip-on or aftermarket exhaust on any of my current motorcycles and won't be putting one on, especially on my GSA. Weight savings is minimal, I don't really like loud or louder than stock anymore; When I'm off-road, somewhere remote, enjoying the serenity, I really don't like hearing overly loud motorcycles or ATVs ruining the peace and semi-quiet, so I like to practice what I preach (no I'm not a tree-hugger); and when it comes to the GSA with Panniers on, you don't even see the exhaust. I also think the current sound of my GSA is just fine. On a positive note, most of these modern slip-ons are really only loud when you are on the gas. Once highway cruising they didn't seem to be any louder than stock.
I'm so at that point of keeping stock exhaust that I think I'm the only Harley owner on the planet that still has his stock pipes on his bike!
Just my experience...
Most modern aftermarket slip-on type mufflers are designed for better flow of spent gases and lighter weight. Practical side is, possibly better fuel economy and lightening the load.waste
I realised exhaust on a GS is a waste of money, too loud and i have to ride with a baffle in it which makes it quiet....and sound like stock! so why spend and not ride stock?
I have a Remus Hexacone.....I dont know how much weight it saves??? But on a 10 ton bike do a few kgs matter?
My opinion only!
Currently in the Marketplace.I have on order the Akropovic Ti Headers - With that in mind I really don't want to spend another $1000 for a Akropovic slip on muffler - so in order to save I found one made in Poland called the Dominator - it looks very well made however must have run very hot and or was positioned too close to my right turn signal as it completely melted the housing. They refunded the money for the torch.
Back to the drawing board - Asking for your experience and opinions please:
BMW R1200GS Exhaust 2013-2017 Carbon Fiber Slip On GPR Black Pandemonium Muffler $475 USD

Any advice or experience with these companies and the quality would be greatly appreciated
That's what I did and it sounds great I drilled about 5 10mm holes.If you want to get a deeper tone when you get on the gas and do it without any cost you can drill some holes in the baffle. It is positioned in the middle of the can at its lower side. You can access it with a long drill from the side of the headers. You take the can off the bike to do that, fairly easy. Four to five 6 mm holes make it sound like the 1000 Euro Akrapovic!
