The non drive side of my SRAM GXP bB won’t come out and I applied enough pressure that it snapped this in half

Any ideas? Or is there a better tool?
Are you sure you’re turning it the correct way?
English threaded bottom brackets are reversed drive/non-drive side (righty loosey for the nondriveside).
Italian threaded are lefty lossey for both (when facing towards frame from relative side).
Otherwise, I’d say take it to a mechanic for further inspection. Maybe it has seized (improper grease maybe) etc.
^^ what he said. There should/may be some marker (arrow) on the BB to indicate the direction of tightening.

Either I had a minor stroke last night or you’ve got that backwards. What you’re saying is true for the pedals but not for an English bottom bracket. On an English BB the drive side i.e. right side as you sit on the bike is reverse threaded i.e. turn clock wise to loosen and the non drive side is normal threaded i.e. counter clockwise to loosen.
I’ll go seek medical assistance after my coffee is that’s wrong. Oh just after I pull an English BB this morning too;)

What frame is the BB in? I use the Park version of the tool you’ve shown and haven’t broken it yet. With BBs I’ve noticed that if one holds a large sustained pressure on the wrench and the BB with very slowly begin to turn and eventually turn out. It’s one case where banging on the wrench does not seem to work although an air impact might work well if you had one on hand.
It’s too late for this BB but be sure to grease or use the appropriate anti seized when you install the next one.

It’s on a trek ttx . I have a new bottom bracket to put in but can’t get this out. I used some wd40 last night and figured I could try a pipe wrench to get it out.

The thing about pipe wrenches is that they tend to crush the item you’re wrenching on to attain grip. I’d have some worry about that ovalizing …ruining my bottom bracket shell if used aggressively. FWIW WD40 isn’t a very good penetrating oil as the carrier evaporates so quickly there isn’t much time for it to capillary into where you want it to go.
Edit add- Well I see it’s been done before.

Do NOT use a pipe wrench! 10" locking pliers will do it.
Source: I just completely stripped a SRAM BB last Saturday and used Milwaukee 10" locking pliers to get it off in <30 seconds.
Any recommendations on an oil?
Did you grease the BB when you installed it? I use Phil Wood grease and have never had to try something like WD-40 to remove the BB.
LBS instaled it, I would assume they did. Bike does see a fair amount of rain.

Blaster penetrating catalyst. Its the best I’ve used, although I’ve never had to use it around carbon.

If this person knew what they were doing it would be fine. A smaller wrench that allows contact between the bearing and the back of the wrench arm would yield three points of contact and prevent deformation.
I do my own stunts AND my own plumbing.
This worked. It took about 20 minutes of steady muscle and then it just quit and turned. Thanks.

Thanks for reporting back. I was hoping it would come along without you needing to go too medieval on it. The one I had to pull yesterday spun right out as it was still well greased. The left pedal however was torqued about the tightest of any I’ve ever removed as if someone had tried unsuccessfully to get it off before and didn’t realized it was reverse normal threaded. Be sure to grease the new one you’re installing!!!
