So my application is more performance then longevity oriented. I also work more with SS and tig weld everything.

The weight difference is noticeable, a little more pain to weld, and I likely will exhaust wrap a bit of the tubing,

Not sure if there is much price difference between the two gauges.

I be welding purchased mandrel bends, so I don't have to bend anything.

I'm leaning towards 18g.

Anything I am missing?


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
