One guys music is another's noise. Riders shopping for sound need to hang around bike events for a bit. Ask about those that sound good to you. You really can't get much from audio recordings. You need to hear the bike on the street.
BTW, I love the sound of my rush, no annoying blatting or harshness that you hear from a lot of others, like the V&H, just music. A good tune will also help smooth out the sound.

fuel pack with slip ons?
Just got back from the dealer. I inquired about slip ons for my 2010 wide glide. He told me that I needed to upgrade to a stage 1 with fuel pack, blah, blah, blah. Said the bike wouldn't run right with out all these added upgrades. Of course, they add up to 1K. When I told him that they weren't recommended by anyone on the internet, he told me internet people didn't know **** and they were to "cheap" to pay. Does anyone know the definate answer on rush slip ons? Do you need thiese added expenses? YES OR NO ANSWERS ONLY...DON'T ***** AROUND...

I called Rush yesterday. The guy said "if you go with the 1.75 or 1.50 you do not need to do anything else. The 02 sensors should compensate". He then added, "technically I am supposed to tell you that you need a remap".
From all the posts I read on this topic, I would say about 75% of the people say you don't need to do anything and 25% say you do. Personally. I am going to try the 1.75s and see what happens.

I too installed Rush 1.75's on my 09 fat bob. Did the research here and thought there would be no popping....Mine has lots of popping. I was at dealer today for my 5K service and told them about it. I said I would buy the stage one and new mapping if that would solve the problem. They said they could do all that but would not promise it would solve the problem. Their answer was that the Rush slip on's just do that and my bike sound and ran normal. They did give me another alternative. HD has a some type of air flow reducer that is installed inside your exhaust where it meets the motor. Just unbolt and drop in pipe. There is a small flange that prevents from dropping down pipe. rebolt exhaust and you are done. A set of 2 cost $31. Forgot what he called it but only small price to pay incase it does not work. Has anyone else heard of this?

... but what you mean by "need". The bike is not going to run noticeably different with any slip ons, certainly safe but you may have a decel pop and you won't be making your best WOT HP or torque, and its possible to not run quite as smooth.... but if you don't "need" all of that and just want to ride then... NO need to remap or other expensive mods. From personal experience, the bike runs fine even with the 2.0 slip ons.
You need to be careful when reading a forum, but if you read the on-line magazines and competent vendor web pages (nightrider for example) you will find that the O2 sensor compensates closed loop (cruising and idle, 80% of your riding) and the bike will run a couple tenths leaner when you open the throttle to accelerate. You only "need" to remap if you start doing cams or headwork, want to get the that last 5 HP or 10lbs of torque.... or are not satisfied with engine heat or drivability.
The factory download is a waste of $$$, use that money toward a good tuner. Every bike is different and a good tuner will optimize your specific bike, not an average map for any bike.

removing rush baffles
Hi , I've had rush 1.50s on my 08 ultra for 2 years an the baffles need repacking . the baffles are rusted in place ! I can't get them to move back or farward . I suggest that if your installing new Rush mufflers put some relief indentations in the edges of the baffles for future removal or be like me frozen in time . Bud

Anything that keeps the air from rushing back in (like a restrictive muffler or deflector) will help. Tuning adjustments that assures that the fuel is burned completely will eliminate the pop. A tuner that adjusts decel enleanment and spark advance can do this.

I don't have Rush pipes, mine are V&H, but I have to give you a cyber high five on this. I can't wipe the grin off my face when I set off cage alarms!

This article seems fairly definitive:
Clip:
Do I need to remap my ECM when installing exhaust and air cleaner upgrades to my 07 and later Harley?
NO, you do not have to do anything. You can put the mufflers/air cleaner upgrades and ride the bike without having to worry about the engine
The simple truth is the 07 and later HD's will run just fine with exhaust/air cleaner upgrades and you do not have to do anything to the ECM at all. Closed loop EFI operation uses feedback from the O2 sensor to maintain a constant AFR, even if changes are made to the exhaust and air cleaner.
