My apologies! I copied and pasted the wrong V&H pipe. I edited my reply.

 

The End

 

I have the Rush 2.0" slip on mufflers on my bike. I didn't do anything else to my bike.......yet. I would like to do the full exhaust at some point but will have to look in to a tuner then. I like my exhaust but would like it louder too. I hear everyone saying the 2" is obnoxious. I don't think it is that loud but that is just me. When I am cruising down the road, it doesn't sound that loud. Just my two cents.

 

My "obnoxious loud" opinion came from a motor that had compression and cams.
Glad you pointed out your observation with those baffles on a stock motor.
Much more accurate opinion for the OP. I should have realized that possibility before I had posted earlier.

I'd still be nervous with a 2.25 baffle without any fuel management on an already lean motor. They flow a lot more air than many of these aftermarket pipes.

 

ok heres the skinny about slip on mufflers when comparing them to stock mufflers. your stock hd mufflers have whats called a "closed" baffle. meaning the exhaust does not travel down an open tube from the headers out the back of the mufflers. what happens is it hits that closed baffle and it re-routed into the fiberglass packing (which by the way is why your bike, if left stock, will eventually get louder due to burning off the fiberglass). anyways... rush slip-ons and HD SE IIs are designed to where you can just bolt them on and roll. the reason for that is they have an open baffle. the thing here is that they have to be constricted a certain amount to where you get the sound you want without adversely affecting the performance of exhaust system (as in it maintains back pressure). i would stick with the 1.75" baffles. that way when it comes time that you feel the need to re-tune your bike your good to go on the exhaust department. you'll have a muffler that is both free-ish flowing and provides good back pressure.

in my personal opinion... slip-ons are the way to go if you want to tune up your bike and still be able to go on long distance trips with out the need to stop every 30 minutes for gas.

hopefully everything i just said helped/made sense.

 

His 2011 Wide Glide has different head pipes than your Street Bob, same as a Fat Bob.
So your cycle Shacks won't fit anyways.

 

I have 1.75s and they are loud as heck.
I Ive ran them without anything else thats not stock for months. Runs great, gets good mileage.
I just did a stage 1, and it changed the sound.
Waiting on the Nightrider 14Xieds to richen it up a tad before I go screaming down the highway again.

 

Go with the 2.25 rember you have a cat converter in your header. No other mods needed if you don't change the AC.

 

went from stock muffs to 2.25 rush, no other mods. great sound, can't tell any seat of the pants difference in performance. bike runs well,very little poping on decleration.

 

Technically, you should have lost a little low end torque. (Less back pressure).
