Here's an idea, show us the before and after Dyno numbers. Would be nice to see the actual numbers. Thank you still a great vid. Definitely would love to see the akropovik full system review. Maybe a head to head? Thanks man

[@ryanxmx31]

The exhaust manufacturer never showes dynos anymore, kind of weird they always used too, I think the stock exhausts are so good they don't make much of a difference unless you do mapping too

[@lukegerler1892]

When is the full system supposed to be for sale to the public?

[@mcgman8058]

i heard they locked the ecu this model year ? So no cleaning up that dead spot on the bottom..

[@SamTimECrasH]

Please test the Akrapovic Exhaust System

[@jpesicka999]

This one is better. Look at that header bro.

[@aanchal5854]

How does it perform in Supercross track

[@bradgraham8272]

I still want to know how bike systems cost more than a full exhaust for a car. 10× the materials. I'm gripping about it but best believe theres a fmf system on my bike

[@newbsauce87]

Because it’s titanium. I guess not really sure.

[@341Fatta]

Would this system fit the 23 FC250 too?

[@vitalmx]

Yes.

[@JoshStreetDesign]

My 22 with 4.1 is WAYYYYY louder than stock, take the spark arrestor out and it is louder!

[@jcmaya1]

Do you have to flash the ecu?

[@ShiftGearsMoto]

No

[@7agol242]

I didn’t find it where can i find a fmf exhaust for ktm 450 sx-f 2023 ?

[@TheDailyQuoteGrind]

If you find where to buy one let me know im trying to find one for my xc-f250 2023

[@boxd1888]

@@TheDailyQuoteGrind u have to go to the manufactor deler that where i got mine for my 2022.5 factory edition

[@Eddiep80]

Yeah good luck. Fmf can’t keep up with demand, or they are being limited to how many that they can produce. I had a hard time finding one for my 21 a whole year later almost.
