I changed from the rear exit H pipes to open side pipes and believe that my engine compartment is cooler although I do not have data one way or the other. I personally like the sound a lot more and do not find it to be much louder. Elimination of the rear exhaust allowed me to install an belly pan all the way to the end of the rear wheel compartment for increased aerodynamics if you're interested in pushing the speed envelope. As for my engine compartment fans, they came from the factory pushing the air up through the hood vents which is my understanding of how they work. Dennis Olthoff suggested, and I took his advice, to disconnect the engine compartment thermo switch compartment and simply use the dash switch to turn the fans on in traffic. Apparently they are not needed when the car is in motion. Others have relocated the switch to a much lower location to keep the fans from running on and on and on after the car is shut off - one of the other reasons Dennis disconnects the thermo switch.
