I would hope/think so. I mean the guy at Hypercoat said it is durable, but it's also not bullet-proof. I'll wrap it in paper or blue painting tape when I install it so to avoid any bangs/scratches when I bolt it back up.
As far as the tip, it's stepped 3 into 4 into 5 lol. I had to sacrifice a nice new s/s Vibrant tip to cut up and use as a 3" into 4" coupler which I then had welded to the 4" outlet 5" slashcut tip.
I would run a s/s tip, not a chrome tip, they tend to look sh*tty in no time.
