Hi, Everyone

I have a '14 390 and I'm quite tired with the stock "coffee pot" exhaust notes and wanted something more bass-y without the need for a fuel controller/ECU piggy back.

Has anyone tried doing a v2 catback exhaust on a v1 390? Now, I'm curious if we can only use the v2 catalytic (without the OEM resonator) and an aftermarket catback if it'll work without fueling issues?

Thanks!!

Your pic shows a V2 exhaust on a V1 bike.... Hanger for the can looks silly though. I prefer the Leo Vince mid pipe and can I have on my 16 vs that for sure... And its had a DB killer that keeps backpressure, so you wouldn't really need a fuel controller unless you ran an opened airbox lid.

Anything that helps keep back pressure would do? I was thinking of getting a V2 header with the V2 mini catalytic that I just bought. After that it gets coupled to a locally made mid pipe and aftermarket exhaust tip
Looks similar to this:

Backpressure is good if you're only looking for more sound and not wanting to get a tuner.... Some people with 2nd gen bikes have used a deep hole saw and cut the factor DB killer out of the stock can to get more sound, there's a video on Youtube HERE. If you get too much of a flowing exhaust, you will want to get a tuner to compensate for the extra flow of the EX.

Appreciate the insights - That is where the bike will most likely go to, untuned with an aftermarket exhaust and see how it goes :)
