2023 V85 Decat

[vf84pc]

On my last ride the temp was in the low 50's the cat put out some heat on my feet. I was thinking of decating the bike.

Mistrial option: $$$$%%

Arrow option: more affordable

Chinese eBay option: most affordable

Should this be done with the Brain boost, V-stack and K&N filter mod? What is everyone's experience?

Just slap on the cheap Chinese unit leave the rest alone.

I was very happy with a full “knock off” exhaust.
Great sound, a small power boost, no fuel/air mods and less heat.
YMMV

I've a '24 E5+ Strada.  I went full Mistral. 10Kg shaved off bike. Runs great and sounds better without being annoying.

I went with the Agostinee system, 10lbs weight loss, super high quality easy instal. Looks great, sounds much better and seems like it has more punch.   I kept the stock muffler and it runs like a champ, no hiccups or off throttle pops.
It is a chunk of change, however, think it was about $900!   But I figured it will last as long as the rest of the bike, not sure that will be the case with Ali Express type?   Also, I thought it was cool it’s made in the same town as  MG!  I don’t have a 23, so it’s a bit different.

I got a decent price on the Mistral headers and I thought the quality seemed the best so I went with them. Before purchasing, I contacted a few of the popular companies to get more info - all three claim to use 304 stainless, and the claimed IDs are listed below. Guareschi never responded to my emails, but their bundle with the UpMap is a solid deal - aside from the tariff's you'll have to pay now.

Mistral - 42mm ID
Agostini - 38mm ID
Arrow - 44mm ID

For the tune itself, I went with the UpMap, which I purchased from AF1. Flashing the bike was easy, and it's hard to describe what an improvement it was on my '23. I ran it with the decat and no tune for probably 6 months, but the tune made it run smoother, cooler, and it's definitely a bit faster - not a ton, but noticeable for sure. The throttle mapping is smoother/less jerky, and I notice much less vibration while riding, especially on the highway - for example: the mirrors are much clearer at 60-75mph on the highway, where before they were often a bit fuzzy from vibrations. If I'd read someone say that before, I would have assumed it was just placebo, I was pretty amazed.

So you did full mistral with the "up map" did you have the Velocity stack or the twin boost? Is the map you used specific to the Mistral exaust?

I have Mistral headers/decat, stock muffler, and an UpMap with a Zard tune. The V-Twin boost is a cheaper spoof solution than the UpMap which is a true tune and (likely - but impossible to verify) changes fuel mapping and ignition timing. The velocity stack could help a bit, velocity stacks are designed to optimize airspeed at certain RPM ranges, so usually they're tuned for more low end, midrange, top-end, etc - but unless you have fancy variable length stacks (very expensive, but cool) you're making a sacrifice somewhere for a gain elsewhere - but not necessarily a straight "upgrade" if that makes sense.

Is the hard tune kind of a general tune? Would you use that map with Arrow headers?
