Default Muffler?

What muffler have you guys used to quiet the L600 down? Mine is straight pipe and quite loud. Any tips on removing an elbow someone threaded in the manifold I've tried everything I could think except the acetylene torch?

Mufflers for compact tractors work well.
Weld a 1-1/4 pipe nipple in the muffler and use a union on the manifold.

Removing the elbow might involve cutting it off with a sawzaw.
Leave some material sticking out of the manifold.
Cut down to thread level in 2 spots close to each other.
Small chisel to dislodge small piece.
Crush remaining piece inward and thread it out.
If you do it right you barely nick the threads.

You’ll probably need to either use torch or saw to get that elbow off. The heat tends to corrode things together (why I like to use stainless for exhaust parts). If you heat it up with a torch, try to heat the outer piece the most, then see if you can yank it off or break it loose with a twist. If it stays really stuck even after a few heat/cool cycles then it’s probably saw time.

Use the heat to expand the metal a tiny bit to break it free. Don’t “glow” the metal or otherwise soften or cut it with the torch.

Thanks guys, I guess I'll try to find a torch to borrow if that doesn't work then cutting time.

Well I was able to get it out with an air chisel and cut off wheel. By the way stanleymuffler.com has loads of options with all the measurements.
