gx390 or p420 mufflers

[PullHorse]

I'm wondering what guys use for mufflers on these engines. My header is about 1.25in OD and seems like most stuff starts at 1.5in intake. Do you simply use those anyway? I don't like the RLV for this application, it's fine for my 212 but this 390 is loud. I could weld together an adapter but I'm wondering what others have done and what they have bought.

Thanks.

I plan on getting a tractor muffler from my local farm supply store (I love tractor supply). That's what I'm doing for my gx390

Have you picked one? Link? I can't really find exact size reducers for say 2" to 1.25. I know I can cut slits and make it fit but just seeing what else can be done.

Dirtbike/ATV mufflers work great and if you're lucky you'll find one that can be repacked
