Default Fat Bob SE street cannons sound mod
Today I was drilling holes in the end cap at the end of the inner tubes of the street cannons. Each tube is perforated with many little holes, muffling the sound quite a bit You need a 30 cm long drill for that. Plan was to drill a one cm wide hole to beef up the sound a bit. But during the drilling the whole cap of both mufflers came out resulting in semi open pipes.

And the sound is awesome not too loud but loud enough. Great success!

Had a conversation with my dealer service manager about this very thing when I had my stage 4 put on. The plan was to do this after the 1k mark but I think I’m going to go with the Bassani sweepers.

Completely different pipes but if those with the street cannons this is a great mod!

I must be confused are we not talking about se street cannons for the 18 fat bob? I know if u look at the cap it’s just riveted on drill out the rivets the cap comes out and boom more flow more sound.

I wonder what impact these type of activities have on performance... I would guess it's not good.

Sorry, no video made.
The bike did go back on the dyno and performance is about the same. 0.2 HP more and 0.4 NM torque less.
