RE: screamin eagle slip ons
When I bought my 03 WG it had the stock pipes on it. The first thing on my “to do” list was to install louder pipes. I wanted to keep the bike all HD so I bought the Screaming Eagle I pipes. After looking at the bore through them and asking about the sound they would produce I exchanged them for Screaming Eagle II pipes. The Screaming Eagle I pipes are close to stock sounding and flowing. The Screaming Eagle II pipes are much louder than the Screaming Eagle I pipes. I was also told “the Screaming Eagle II pipes do flow more than stock pipes and therefore the air/fuel mixture can go lean causing heat related motor damage. HD recommendation was to install the stage I breather kit that would flow more and larger idle jet to maintain the correct air fuel mixture caused by the additional air flow”. I did that and also removed the mixture plug and set the needle valve. It was worth the trouble as my WG doesn’t sound like a Honda anymore! Also, what a difference in performance and sound, now it sounds like a Harley! Did it absolutely positively need the stage I breather kit? I would say yes on the grounds of “better safe than sorry”. Any damage to the motor caused by heat due to over lean conditions will cost much more than the 150 bucks for the stage I kit. I have a carb on my bike, I would think that EFI bikes would need the same modifications to the air fuel.

You don't need to do a Stage II.
However, look at a Stage I and download to go with the screamin' eagles. I have that combination on my scoot and I really noticed the difference when it was done.

with the O2 sensor, you shouldn't need to do anything when adding the slip ons. For sure not a stage II download. Just adding pipes is half a stage I mod. It is slight enough of a change, it can be compensated in the ECM automatically (hence the new O2 sensors they came out with in 06 for Dyna's and all models in 07)

Here we go again. Black, I was told by the Stealer that I didn't need to do a download when they installed the high flow and SEJUNKII"s.
This is a pic from my '06 Lowrider with 7500 miles on it. You be the judge from the looks of my end caps. that ain't dirt!
I will have the SERT prior to spring.

well, first of all he only mentions changing out the pipes, not air intake. Also, he won't be buying SE II's.. and, I don't see anything wrong with the soot in your photo. I don't think I have ever seen a spotless exhaust.
My 05 doesn't have the O2 sensor, so I dit a few mods, all stage one (big bore, intake, seII's, and a PCIII). Bike was dyno'd and had a great a/f ratio. I still had soot on the interior of the exhaust.

You may want to do the Stage 1 flash. I have the SE II slipons with stock A/C and at the 10K service the dealer noted that the bike is running lean ('06 Dyna). So I just had it flashed today. Also Santa is leaving me a high-flow A/C under the tree and I would have needed it flashed anyhow.
