Arrow Headers don't fit OEM Muffler

Are you guys getting the ecu remapped to go with the Arrow headers?

Yes, done at the same time.

How do you like the retune and where did you send it?

It’s difficult finding a good motorcycle tuner over here. Netherlands is small and doesn’t have a real tuning culture like the UK. After getting a lot of information and experiences from others I send it to Carmo Electronics. Made clear what my wishes were and got it back in a few days. Gov has gone absolutely mental with road salts and brine so haven’t ridden it yet. But she sounds powerful and vibrant.

I weenied out today and installed nyloc nuts on the exhaust flanges but I feel better.

I am really happy with the new exhaust at the tune. Highly recommended, 5 stars, don't hesitate. I used 2 Wheel Dyno Works outside of Seattle.

Out for a drive today, I think the open exhaust fixed the engine braking issue. It really appears normal now. The idle thing has yet to be determined but it could feel better at off idle acceleration. I wonder if the ecu relearns the new conditions.

Dont know about outside UK but here our bikes are " tuned " to pass i believe its a drive by test in top gear.Thats why they are flat at that RPM. Its worth getting the ECU done just to get rid of that plus matching the Arrows to it is a bonus.

Same, the Powerband had two “flat spots” in it. Explained to me as: at one they measure noise (rpm and DB noted on the white frame sticker) and the other pollution (euro4).

Not just us then. Its on our V5 registration document. You kind of get a stumble at those revs.

I purchased the Arrow Headers for my 2020 Super Tenere. Everywhere i've read indicate they are compatible. However the end of the headers is smaller diameter than stock so the muffler pipe that fits over it is too large. Not sure what i'm supposed to do to fill that gap? Was a gasket supposed to come with arrow headers? Am i supposed to purchase one separately somewhere ?

Please don't tell my Arrow headers and oem muffler, They've been happily wed for several years now. It was a single ring ceremony using the old oem gasket.
