One good reason to get rid of it! I've had zero problems after removing the heat exchanger in favour of an oil cooler, definately keeps the oil temps in check during hard use.
Keeping the heat exchanger in place means you're trying to heat the oil and cool it too, the oil cooler is far more effective at cooling than the heat exchanger, keeping it in place compromises the oil coolers performance.
It is generally recommended to remove the heat exchanger when fitting an oil cooler to get the full benefit of the improved cooling. Keeping the heat exchanger in place with 100+ degree coolant running through it isn't a very effective oil cooling solution.
