Exhausts and Engine » My Full exhaust photos

So flipping parts from my Tiger towards mods for the BMW that won't be in the USA till June 30th and another 15 to 30 days to dealer .
Can is a nice ZRX 1100 or 1200 52 mm inlet Titanium and Carbon fiber can from Akrrpovic .
The Mid pipe adapter is a titanium unit from overseas seller that is listed for all 1250 motors to use any can one would like .
Header is Blackwidow , and its welds are very good tig welds . Entire new system is 9 lb 4 oz.
The stock can alone is 11 pounds and OEM header about 14 pounds .
Stopped by Wild West today , and ordered new header gaskets .

Looks good.
Will you be able to use a shield to cover the connection at the can?

Yes Lee the is a screw and tab to attach the cover to .

Well it will be interesting to see how this turns out ... I assume your going to put the bike on a dyno. When you do you should get a video of it, there are none on the RS that I know of for re-mapping, if you can get the tech on board .....

Personally I have to speak out against ditching the Cats and replacing the whole exhaust. I watched a video by 650ib where he replaced the entire exhaust on his new M1000RR and the result was an very very small increase in hp. The stock stuff just works so well especially if you compare it to the very first cats from the eighties .... Out of around 210 HP the new exhaust made something like four more HP! And it smoothed up some little bumps in the curve but overall it was amazingly disappointing .... imo

I put an SC-Project can on my RS to save the weight. So I can rationalize that I made up for the new tool kit and tire plugging kit and maybe a bottle of water ...It does seem to bee slightly faster but it is hard to tell ... The bike is already crazy fast lol ..... And I didn't have to put it on a dyno to re-map with just a can ....

with three O2 sensors it can adjust enough on its own . NO ECU flashing or tune planned or needed . I have removed Cats on everything from FJR / Triumph Tigers/ Hayabusa's all for Weight reduction not power . Todays Cats flow very well . The gain is weight reduction , and on some bikes heat reduction felt to riders .

When placing the Hayabusa on the dyno it was still overly rich and throttle plate restrictions at certain rpms . The slight change in tune just opened up some power gains in mid rpms and gained 5 peak hp from 202 to 207 RWHP .

OK but it seems that some program changes might be needed. If your not putting the bikes on a dyno then you may, very well, not know what is really going on imo ... good luck I mean no harm ....
I tried to pull up that tube video but it looks like he edited out the before and after, prolly out of embarrassment. He does have the "after" the strait pipe posted for both the S100RR and the M100rr from that year 22 i think, which made 202, 203 hp respectively. I think the tech was just barely able to get back to the stock HP with a very slight increase with many many dollars spent ...
So I've started to wonder if the cats are actually helping the flow somehow like say an afterburner effect of some sort. the private tuners are having trouble getting the same power out of bikes after the stock pipe is replaced.... Not to mention the possible legal problems with taking off cats ...
I like being able to start my bike up in the car hole and it is not a problem really, don't even notice the exhaust and it prolly runs better anyway .... imo

Contacted Blackwidow , and they said no codes or issues with third O2 sensor . I'm happy to report they are correct . My 2023 RS sounds amazing for a boxer . Best one I have ever heard in person or video . Saved 13 pounds off the new RS . One thing I like is its still quiet on cruise but when I get on it the sound is there but not annoying like a sawed off squids motorcycle . Also can now hear the shift cam action in the exhaust note . Think OEM Turbo car when coming into boost . Just enough to make a smile .
