Default Fat Bob 114 stock vs SE slip-on difference?

I have a 2019 Fat Bob 114 with stock exhaust. In the outlet pipe there's 12 rows of 10 holes (about 5/32") each plus an end baffle in the 1 1/4" outlet. Can someone with Harley's SE Street Cannon slip-ons please have a look and see what's there for number of holes and is there still and end baffle?

I'm simply wondering if it's worth spending the extra this winter for them vs stock exhaust. I'm not after more noise. If I want power a Stage 2 cam is the right step but I'm happy so far as is with the 114, plus there's no dyno shop locally.

Not worth it. You gotta go stage II for any real gain. The 447 torque cam will get you more than a 20% power increase. No dyno needed, its all plug and play H-D parts.

Yea that's what the tests and reports here indicate. Thanks. I was just wondering what changes there may be in the SE Cannons for the Fat Bob that's worth that much more $$$...what's to gain over the stock cans unless there's more outlet holes or no baffle? The Cat's my be in the header crossover on the Fat Bob and not the cans.

The street cannons are only a few decibels louder than stock, since they are epa approved that’s all they can be. I doubt the pipes themselves offer any performance gain.

Thanks for the replies guys. I found out what I needed here: https://www.hdforums.com/forum/softa...-question.html

HD puts a plug in the stock FXFBS 114 cans about mid-way along the drilled core. Forces the exhaust out the muffler core's header inlet side holes and back into the core via the remaining outlet side holes. Folks drill or punch out the plug and save themselves $$$...unless you like black then paint the stock cans with high temp paint. The Cats are in the headers as I suspected. The Street Cannons may have a larger diameter core....the stock is 1 1/4".

Edit: I searched and read some of the many good threads on Stage II especially for the Fat Bob and 114 engines. I'm going to stick with stock intake plus K&N element( which I had on a 114 Heritage this year), stock exhaust and cam. I want no more vibes which the Stage II as reported here can create, and the bike is plenty loud for my 73 old ears. Snow's on the way to Alaska in a few weeks so that's that for another riding season.

The SE mufflers do get a bit louder after a few hundred miles, still sedate but throaty. Getting ready for a cam upgrade myself and going to stay with the set-up (dealer stage one from new) aside from a new K&N filter element.
Cheers!
