Stage 1 for the Fullsac / Bobvic slipons?

Do you have to have the Stage 1 upgrade for the Fullsac or Bobvic muffler mods on the OEM mufflers? I have an 06 RKC and don't want to harm my motor by running too lean. Also will my warranty be voided by running these recored mufflers. I've ordered the Bobvic superflow{removal of the 1-1/4" core and replaced with a 1-3/4" core.} I do not intend any further engine mods. Just want the Harley exhaust note that 18 grand couldn't buy!

Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)).

So if you install pipes and the transmission blows, your still covered under warrenty because the pipes have little to no effect on your transmission. But if those pipes cause so much back presure that the heads blow off, then the repair will not be covered under warrenty... Make sense?

Its all covered under the Magnuson-Moss Warranty Act. Read more on it here:
