Boulevard M90 exhaust

Hi everyone,
Picking up a 2010 m90 soon and in process of grabbing an exhaust for it.
The exhaust I'm looking at doesn't have a cutouts for the o2 sensor, therefore I'll have to use a o2 eliminator. However would I also need a power commander and auto tune module? Or is stock ecu good enough to handle the exhaust without running too lean to the point where it affects the reliability?

Just the Power commander here is Australia will cost well over $1k with the auto tune module so I'm really trynna stay away from it, the exhaust costs 700 lol

Well you COULD be a responsible upstanding member of the riding community and leave
the stock pipes ALONE and not be an outlaw.

That way, you wouldn't have to worry about ANY of that.

Noted :)
When I bought my C50 2 years ago, it had Cobra pipes with supposed baffles. It wasn’t super loud, but it was loud. When I bought the C90, it had a fully stock exhaust. At first I thought that I might want to change it out, but as time and miles have passed, I have come to love the quiet deep rumble of the stock pipes. I no longer have any desire to change it out.

May I ask why yuh don't just have the pieces cut out of your old pipes and welded back into the new exhaust in an un noticeable place?

You don't even have to have the bungs cut out of the stock pipes, find a shop that can weld some on your new pipes. Not sure the stock computer will work even with the O2 sensors, because it's probably programmed for the flow from stock pipes.
