Mine hasn't sprung a leak >>> YET! But I'm sure it's day is coming. Saw quite a bit of corrosion inside that pipe last time I looked.

I hate cutting pipe so it fits with another pipe at weird angles. Kinda like cutting crown molding to fit a sloped ceiling. The section over my fire place is about 10ft long and I swear I burned through 4 trees making it correct. lmao.
