Default Cams exhaust note

Hello,
I am currently switching to a hammer 100hp kit
I will be using the impact 560 cams. I am used to the exhaust note changing in cars with a cam change ; what will I expect in my 1250 for a change I'll be using a patriot defender? I didn't want to ask but I can't seem to find an videos!
Thanks everyone !

The exhaust sound? It will be unrecognizable. Yer friends will not want to ride behind you.
The bike at wide open is race bike loud .. The potatoe sound will be gone.
it will set off car alarms and scare small children
The use of the butterfly valve is recomended around the house.

What a sound! I'm sold already and the dyno sheets are impressive compared to more expensive pipes! Beautiful bike as well!!

Does anybody know how it would sound with a 2 into 2 like the Rush 3" slip ons?

Better, deeper but still loud. The Khromewerks HP Plus slip ons are an even deeper loud and despite the deep sound and great low end torque, they're still an open baffle you can see thru. I'm betting they give the PD a run up top even more so than the Rush.
