I call BS on that dealer. Just trying to sell you more stuff.
The CFR's are extremely free flowing and have a reputation for being hard to tune, most likely they do mot provide enough back pressure as a result of the mild, low RPM friendly, cam provided in the stock HD engine. IMHO CFR muffs are more suitable for a stage 3 or 4 engine.
The HD Street Cannons, HD air intake, and vin specific ECM download is a proven combo that makes the bike run well and efficiently. It's All that's needed for a very street able bike typically about 82-3 hp and around 98-100 tq
Good info Bluesbelly. I can definitely tell the bike runs a lot better with that SE setup
