Slip on exhaust thread
#1
Yo, thought it might be an idea to get a slip on exhaust (or full) thread going. I imagine the 1200 and 1250 stock exhaust note must be similar.

Lets start with a stock 1250 by Schaaf (1200s can't be far off)

I don't think you can go wrong with any of the ^^^
I will stick to stock at least for now, but am a fan of Arrow.

Thanks for posting! I'm pretty much sold on the Arrow as well. Not looking for more noise, just maybe a deeper note and an aesthetic change.

Here's one of the Arrow, in Black, on the Imp Blue RS. Not much to it, but a good look...

Here's one from Europe (Spain?), so it may not be an exact duplicate of a US model, but the Arrow sounds pretty good on the road.

You don't need to listen to the whole 7:33 to get the idea, but it's some nice scenery!

The 1250 exhaust sounds different to us.
The muffler looks the same but I think the flapper valve is different.

The shift cam engine sounds different to me too. In addition, the engine exhaust sound changes quite noticeably when the shift cam shifts. I have heard this change under partial load and gentle up incline in the mountains.

Even though I am a fan of Arrows, I like the look of the heat shields on the Remus and SC Project.
Got lucky and found a SC Project at a have to buy price.

I researched for ever to find my exhaust. There were no exhaust videos, so i took a leap of faith when I bought it. MAN am i happy!

I bought a GPR Sonic slip on Titanium model. The slip on comes in stainless and titanium. It has removable baffles that make a pretty big difference in noise.

GPR customer service is great too. I bought the exhaust off their ebay store. When I recieved it, the black tip was damaged due to bolts rolling around in the packaging. They took it back and sent me a new one no questions asked. Payed for return shipping too.

I just added Black Widow headers tonight. With the catalytic converter gone and the baffle taken out, the bike pretty loud. I needed to put the baffle back in. The muffler/header combo sounds incredible.

The header gave the bike noticeable boost in power. No more flat spot and it just pulls and pulls. I found myself accidentally bouncing it off rev limiter on the test ride after the install. I never used to do that before.[Image: c114e7215e81e6531e7518120fde344f.jpg][Image: f4bd66ce199e2e070380d30280c839c2.jpg]

If you haven't watched this company video by Akrapovič it's worth the five minutes. They uniquely have their own titanium foundry, and I think they're one of the few that do all their own casting, rolling, cutting, and welding of it in-house.

As for the looks and sounds of their products for the RS, it's a bit of a mixture and dependent on what you get from them. I think the can looks too fat. Why can't it be more slender like the can on the R1 in the video:
   

Aren't we more concerned about sound, though? I am, but I think Akras are really designed as system, muffler & headers together. I think their de-CAT'd systems with the baffle & dB killer left in may provide a great compromise to be non-offensive & very approachable at low RPM/throttle inputs, but awaken the beast if given the beans -- sort of what I attribute to the rest of the character of the bike anyway. The can by itself is OK but I think an Arrow or SC Project sound much better and have a FAR easier-to-remove dB killer.

Speaking of exhaust sound...

Just watched "The Batman". Bruce, being a man of style and significant substance, chose a BMW boxer to power his vehicle of choice for most of the movie's vehicle scenes. Not the shaft drive, though, because in some shots you can see a chain. Not many close-up shots.
   

Here's some video taken of filming of one of the bike scenes, recorded in downtown Chicago. Check out the (lack of?) exhaust. Mostly idling and revving, skip to 7:20 to see & hear it drive off. https://www.youtube.com/watch?v=kurIuBZZsrs
