I had mentioned this in a previous thread and forgot to upload the instructions I received from Borla as to drilling weep holes in mufflers that do not have them already.
A bit of backstory is I have the ATAKs and they got a considerable amount of water inside the case due to rain/snow and the fact I drive short distances in cold weather.
This started causing a buzzing noise. I called Borla to verify that drilling the weep holes would not void the warranty on them. (Not going to junk $700+ mufflers).
They said it is perfectly fine to drill them so long as I follow their instructions. Keep in mind this is for Borlas but it could be applied to any case muffler.
However, check with the individual manufacturers as to if they void the warranty for it or not.
I have the instructions attached.
