Could backfiring be the cause, regardless of 320/360?
Another Univair muffler with 200 hours. 160 hp.

I recieved my new nicocraft (wallcolmonoy) muffler yesterday. Bought it from aircraftspruce. The muffler bale is welded in too low in this tailpipe aswell... Does not even enter the muffler body..
seems as all nicocraft muffler bales is welded the wrong way. The old muffler is at least 10 years old.
money back possible?
Are those pipes still bolted tight to the engine? If so it sure looks like there were some stresses in the installation.That's why I went with the gutted hot rod muffler. Still looks like new inside. Makes up for the 2 lbs too.
Speaking of weld cracks tho. 900 hrs

Naw. It pays to have lots of spares.Those look like they can be expensive.
base nuts still on cylinder tight? heard of muffler stack being only thing holding on a cylinder....
You read it rightI had misread that as loose exhaust nut...
Why I hang out here, though I fly behind a Rotax 912S...... you guys have a lot of fleet knowledge helpful to even a non Cub flier.
I currently have 2340 hours on my muffler, with zero issues, BUT, this thread will make me check things over more often, and "more better." Original heat muff also.
Ha, I forgot about this..... At 2600 hours, I started hearing a rattling sound, turned out my muffler had shed it internals, thus the noise. A simple fix (new muffler, though in retrospect I could have repaired the old one with what I know now, the stainless can was fine, just the baffles needed replacing), and the heat muff was still pristine so I put it back on.
