That's why I'm asking. I'm not being an ass. I honestly want to know what other options people are using. I'm trying to figure it out as well that's why any type of exhaust modification won't happen for me till there is a solution.
I've been riding, racing, and woking on motorcycles for over 40 years. As stated earlier, all motorcycles run lean to pass emissions. All bikes could stand a retune to run "better" regardless of modifications.
If you are only putting on a slip-on, it will "probably" be okay. But a full exhaust is definitely another story.
No offense to your buddies but "seat of the pants" dynos are far from accurate. A lot of people feel with the louder exhaust note, they think their bike is faster, but it's not. It's just louder. I ride with several street riding groups and there are guys who have full exhaust and no retune and they'll swear up and down, their bike is fine. The only real way to see if you are properly tuned is to put it on a dyno and get it measured.
Personally, I never do a exhaust change out or mod without a reflash or retune (performed on a dyno). For me that is all part of an "exhaust mod". If you are doing the change out just for looks, then go with a slip on. It's cheaper. But if you are truly after performance then a full exhaust and retune is the only way to go.
I'm going to check a local shop north of the city who has a dynojet dyno and a certified Ducati Mechanic and see what they can do. But there is too much snow on the ground to get there. Probably won't be for a couple months.
Have been reading generally and also some of your related posts in other places. If I was the kind of rider to rarely go over 2/3 throttle, would it still be an issue ?
Many of mates on the 790/890/1290 have full systems without any remapping and their consensus is nil needed … but that is just an opinion.
I have the Unifilter foam filter coming too, but I believe it is more for dust and better fitting than air flow.
if my dealer won’t put on a more suitable map (perhaps a Termi map would suffice???) then what does one do?
