This is a good video regarding the process to remove the catalytic converter and there's still enough back pressure from the mufflers according to the dude who did it.

Wouldn't mind trying this, but of course it's a permanent thing and I can't imagine replacing the header pipe is cheap knowing Polaris spares and accessories prices.

Thoughts?

I removed the Cat converter the hard way, drill, long screwdriver/chisel hammer and plenty of patience.  No welding.
There isn't much back pressure with Stage 1 pipes. Stage 2 cams fitted.
Without fitting a Power Commander it would fart and pop when backing off and when blatting the throttle it wasn't too responsive.
With PC fitted and dyne tuned it is a lot more responsive.  Have yet to see what the fuel consumption is.

Yeah but shipping to Australia makes it uneconomical.

Since fitting PowerCommander fuel consumption hasn't changed. Still getting a little bit of popping on back off but not worried about that.  Dyno tune got 93 horses out of the 111.  Has a even power band across the rev range. Goes well.
Might have to fit some pipes that produce a little bit of back pressure to completely eliminate the popping.
