Welcome from New Z. Rob. Fill out your profile a bit and post a pic or two of your X. How are the roads over there? Any corners?

Any cops?
I'm watching those pipes for laughs (pricewise)

as I'll never pay that much no matter how nice they are.

I see what you mean now after zooming in and I checked both my bikes. Both of them have these spot weld? indentations on the exterior cans where the baffles inside are probably attached (my guess). Never torn one open to see but what else could they be? Nice that they're located on the inside/bottom. I've seen indentations like these on Toyota pickup beds around the wheel wells. Totally smooth 'cans' are surely possible but remakes are just that, copies of the originals, flaws and all.
Here's my Z model with over 50,000 miles, on a recent trip over the Sierras. The tank sides were repainted and I'm too lazy to place the striping and decals back on.

It ain't the destination, its the journey...
