So I've got my cam job coming up in about 2 weeks and trying to figure out this whole exhaust and losing bottom end thing. Currently have magnaflow knockouts, 4 inch, on my 2019 cvo street glide. I love the sound and looks but am afraid I'm gonna kill my bottom end after the new cam. Just for s#!ts and giggles I put the stock cvo mufflers on today and went for a ride. First thing first, the sound made a tear roll down my cheek, awful! Guess I've gotten used to the magnaflows and it is a WORLDS difference. Bike is stock and I could not tell any difference in performance with the stock mufflers over the magnaflows. I'm being told the difference will be much more dramatic with a cam. Now to my original question, does anyone here have 1st hand experience with stock cvo mufflers vs fuel motos street outlaws on an M8, talking about sound wise. If the street outlaws are even remotely close to the stockers sound wise, I just dont think I could deal with it. I've listened to quite a few videos and I can tell they are choked down but it is hard to really tell from a video. Thanks for any help or input!

 

Can not speak about the magaflow mufflers, I can speak of cams though, the extra flow from lift, duration, timing make all motors louder using same mufflers. the M8's really do need some back pressure to run efficently especially down low. Depending on the cam a tune is absolutly needed to keep your engine running right. Good luck on your quest.

 

Quik, I've sent you the PM response, I hope that helps you out a bit !!

 

Quik I have been wondering the exact same thing, except the stock slip-ons, not the CVO's vs the High Rollers (same baffles as street outlaws). I have heard they have a very low rumble like the CFR's, but I would love to hear these in person.

 

I went from SE to street outlaws and there is no comparison the streets sound 10x better but I went from a 107 to S&S 124

Well that changes everything modify a M8 with any performance cam, more cubic inches and fuel programmer it will sound better regardless any exhaust.
