My 2020 Harley Sport Glide has been a fantastic ride in the 5000mi I've owned her. Looking to get rid of the "sauce pan" air cleaner trim. Many of the chrome and natural catch my eye, but I do not want to use the SE tuner and would prefer a "low" air flow filter until the warranty is over, then go with non-OEM tuner. Are there any nicer looking air filter trim covers that do not require a tuner? Also, bike is stock except for Rhinehart muffler.
If you've already installed a slip-on exhaust, and are planning to put a new air cleaner, you really should get a tuner. Your bike will be running lean and hotter than it should be. The SE is the only one that won't void your warranty. If you invest in the tuner, then you can actually buy the air cleaner you want, rather than wasting money on a decorative cover for your stock cleaner.
You don't "need" a tuner to run a different air filter. And I would bet that the stock air filter doesn't start to impose an air flow restriction until at least 4k RPM's.

No he does not "need" but he already has a free flow exhaust and putting a high flow AC on there is going to cause issues in the long run as he is already very lean in his fuel mixture. Also very likely he will throw engine codes due to the fuel/air mixture.

I thought that running a less restrictive exhaust and OEM intake did NOT lean the fuel mixture. For those that have facts on this please chime in.

Doc Harley has a video on exhaust and tuners. The ECM allows for a 10% variance that can be handled in fuel/air mixture. The slip-on he has eliminates the cat which means he is now moving more air out of the exhaust, when you add a high cap AC to the bike he will then be moving more air into the bike. Without changing the mix ration he is going to be way too lean. The ECM will not be able to compensate for the additional air moving in and out causing it to run hotter and possibly throwing codes.
This is how it was explained to me by multiple mechanics both dealer and indy and the reason why I am not completing my stage 1 till now since my warranty expiration date is 8/17

Correct. If anything the A/F ratio will go rich, but not until higher RPM's when/if the flow capacity of the stock A/C is exceeded. The ECM will try to adjust but if it can't it will throw a code.

You are fine with the just exhaust, the ECM will compensate for a slight difference in spec. I have done about 15,000 miles with the TAB slip on without any codes
