Since the stock Bagger system is technically a 2-1 I'm not sure how plugging up one muffler is in any way, an improvement.
The fact the OEM system uses 2 mufflers to expel exhaust (after the 2-1 collector) this also means there is twice the exit volume.
With 2 muffs you can use more restrictive (quieter) muffs without giving up performance.

Walked into my HD service department today and talked to them about removing the cat from from my RGU. Response was, no problem. I asked if it would have any impact on my warranty, and they said, yes - it will void your engine warranty.

Maybe it's every dealer makes their own determination, I don't know, but I was disappointed with that response.

The system produces better power as a 2-1, but it would still give you the option of having 2 mufflers. He did say that a decatted stock head pipe is actually a pretty good header.

After much arguing and hell raising, the dealer covered part of the damage, the owner ate the rest.There are also a good many people who work at a dealer that have no clue as to what is a and isn't covered under warranty.

And the only way the Parts counter will add components to the VIN is by having the parts installed on your bike by an authorized dealer within the first 60 days after a new bike is purchased. If you ask the parts counter, they can usually print out whats covered under the factory warranty or ESP for your VIN. This is the same report that the HD Sales Department will use when they determine what will be covered under the Harley (or a 3rd Party) ESP.

If you add a stage kit upgrade after 60 days, it will have a parts warranty but it will NOT be covered under your 2 year factory warranty or any future Extended Service Plan.

Your own your own for the upgrades after the parts warranty expires if you had it installed after the first 60 days of ownership.

I'm good with HD warranty not covering aftermarket products, but what I don't want is aftermarket products voiding my HD warranty.

Only HD products purchased and installed during the first 60 days will be added to the Factory warranty or ESP coverage.

Any aftermarket products (tuners, cams and exhaust for example) that are not 50 state emission certified can result in a drivetrain warranty claim being rejectd by the Harley Davidson corporation as named in the EPA Settlement in Aug of last year.
