I 2nd, 3rd, 4th, 5th this. With a dp/fp upgrade it sounds so bad with the drone when reving down. But on stock it's not entirely too bad.A muffler delete with a stock downpipe is manageable - ran it for a year no problem. The trouble starts when you add an aftermarket downpipe it totally falls apart, and becomes a droning, raspy, fart can.
I'm embarrassed to share that this was my lawnmower for a few days while I rushed to find a dedicated exhaust once I added a downpipe
