Deere X739 Exhaust Mod due to high Carbon Monoxide levels inside the Cab.

Last year I bought a new Deere X739 with the Factory Dealer installed Cab. While it was an improvement compared to no cab it was still a bit chilly on really days and the CO levels were lethal due to air infiltration . The engine cooling air intake point is inside the cab under the dash area. High negative pressure inside the cab pulls outside air into the cab from every seam or hole, I attempted to seal up the gaps with painters tape or foam tape but had limited success. I made some temporary exhaust mods which resulted in some improvement but blowing snow always lead to a headache and nausea.
Here are some pictures of the mod.

Hey

SP or SR?

I've got a 69 SP ;-)
