Is there an aftermarket option for these intake boots, mine is torn and I'm getting a good bit of back firing. I read it may be this but I can't find a new or used one... someone please tell me what to do.

When I pull up 400 is shows like this

Mine has the two separate pieces I think. It's at least in two separate pieces now.

Oh, your looking for what Cat calls the intake manifold that holds the carb. The 375 and 400 share a lot of parts. There is possibly a way of fixing this boot. You will need to remove fully off the engine. Thoroughly clean it to de-grease it. Buy a tube of windshield urethane from an auto glass shop or an autobody supply store. It comes the size of a silicone tube so a normal gun is all that's needed. spread the crack a bit and get some urethane in there. Coat the outside rubber without compromising the mounting flange or where the carb mounts. It does not have to be thick. It is important to wear nitrile gloves as you can't get this off off your hands or clothes.

Yes I do agree windshield urethane would be the best. But I did mine with Permatex The Right Stuff 6 years ago still holding today.

I'm gonna stop at advance today and pick something up. Got to take it back apart anyway because I think the new carb jet might be a 125 and the FSM says 142. Hope I didn't chuck the old carb. Don't know if this could also make it backfire/pop. Either it's these things or the cheap aftermarket flywheel. But I wouldn't think so because it randomly happens.

Update: I rejected the carb and used BetaSeal 428 Plus on the intake boot. She runs runs like a bat out of hell. I don't know how long the boot will last but as of right now it's running great. I appreciate all the advice and help. Thanks guys! Next up, u joints for rear drive shaft. SMH.
