Hi, i need louder sound ktm 390 adv. it has 2 cats (catalytic converter and pre-muffler ). I bought from ktm powerparts akrapovic but it doesnt work - same sound compare with stock muffler.
1. Coober kit

its nice tune but pre-muffler is there so sound will be deadening.
2. Verex only pre-muffler delete

and i have to buy powertronic with their costum tune. i dont know if it is compatible
3. Verex Full Decat Pipe

BUT how should combustion work, without any back pressure?
Probably i have to buy powercommander and get dyno tune for my local motoservice dealer
pls any idea? i was hitted by car on traffic (wasnt my false) thats why i need loud sound
thank you
