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
or
BMW R1200 GS ADVENTURE 2017 2018 LEOVINCE NERO SLIP-ON EXHAUST $511.85 USD
or
Scorpion Serket Parallel Slip-On $543.60

Any advice or experience with these companies and the quality would be greatly appreciated

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?

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...

That makes two of us Harley owners with stock pipes. They will open up a little after 8,000 miles; at least mine did.

My '05 runs a Remus system. Came on the bike and I don't know why the original owner made the switch, other than $$$$ was not a consideration. He also gave me the factory units. I do love the sound and performance but cannot make a judgement on the difference as I have never ridden the factory set up. Wondering what the difference is.

BTW have you checked out the Danmoto units. Had one on my Suzuki Bandit GSF 1200

Give Remus a try

You may want to try contacting Patrick at Remus and see if he can give you a deal on a Remus slip-on--he gives discounts to board members. His email is [email protected] . I put on a complete Remus system--header and Remus 8 slip-on can on my 2017 GS and like it a lot. I also added a booster plug. It looks great. Did it improve performance? I think so but honestly it may be placebo effect. But I definitely like a deeper, louder exhaust note. The Remus 8 with baffle removed is definitely deeper and louder than the OEM. I'd have liked it a bit deeper, but it's pretty good. BTW, I'm not a representative of Remus :wink2:

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!

Remus 8

I have just ordered a Remus 8 slip on and am hoping for a slightly throatier exhaust note - I have to wait a while to get it as none in the country presently. Hopefully I won't be disappointed as they are not cheap!

My opinion only!

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.

Every bikes I ever owned with an aftermarket exhaust on it once properly tuned the fuel economy went down. Since you had the ability to flow more air more easily you needed to richen a/f mixtures in some places and lessen in very few to get proper performance. Simply installing a slip on will really does nothing for performance but does typically increase the dB level of the exhaust. In a lot of instances performance will actually suffer until you address all the parts of the equation. A motor is really nothgin more than a big air pump. If you can get more exhaust out you can cram more air in. If you can get more air in and more exhaust out you need to add fuel in proper places in the proper amounts.

Loud pipe save lives!

Remus FULL exhaust system (for R1200GSA)

Remus full exhaust system (header & muffler) in steel (NOT titanium). Used on a 2017 GSA for one season before selling the bike. Paid $1700 new for the set. Perfect condition. Header has been painted satin black with Cerakote high-temp (1800 degree) paint (better than powder coat for high-temp)...

That's what I did and it sounds great I drilled about 5 10mm holes.

I found some factory take-offs on eBay for a friend for under $200 shipped.

This seems to be an opinion thread, so I’ll give my opinion.

Why bother with a muffler? I mean seriously. Loud mufflers don’t impress anyone, they only come across as annoying. There’s no question that having a throatier, deeper sound than the stock might appeal to you as a rider. It does to me. But is the cost worth it? Besides, you’re wearing earplugs—what exactly are you going to be hearing after spending $1000 or more? Finally, the 1200 is a utilitarian bike, like a Swiss Army knife. It’s not designed to be a cruiser that you can decorate like a Christmas tree. If you want a Christmas tree, get a Christmas tree, and decorate it to your hearts content. But decorating a Swiss Army knife seems a little silly to me. JMHO

Why bother? During last 30 years loud muffler helped me with lane filtering. I am being heart and cars move away. In the city streets pedestrians hear me and don't launch themselves from the curb stupidly as they usualy do. When I'm in blind spot of the car besides me, he may not see me but he can hear me. Well I could go on with this...
I dont give a shit about impressing someone, I just care about me. And I haven't started to ride and modify my bikes yesterday. It was 38 years ago.
