What geared dc motor is best to use for a custom automotive exhaust.
(OP)
I am making my own exhaust cutout that will have a exhaust valve open and close by switch. Does anyone know where I can find a geared motor or geared servo motor that can function reliably in extreme temperatures, it will be also be used in everyday driving conditions, any input would be helpfull, I would like for the motor to be reliable in a general term and would last me over 5 years at the least

Bosch is a safe bet. They have lots of sturdy DC motors that can sit in dirt, water and ice for years.
If you want something cheaper, Parvalux has a range of motors where you either need to build a protective house or have to accept changing motor now and then if you drive in dirt and ice.
Either way, the Control Circuit can be extremely simple. Just a DPDT switch that connects motor via an incandescent lamp to +/- or -/+.
See http://electronicdesign.com/components/lamp-elimin... for details.

If you want to use a "Brand Mark", you can go to http://www.servocity.com/html/3-12v_gear_motors.ht... But they will cost more.
My experience is that the chinese motors are quite durable. Especially in a dry climate.
The motor as such will fit easily into your $100 budget. In fact, I think that you could build the whole system at less than half your budget if you use the solution without limit switches, as shown in the article, and a manual DPDT switch to open/close the flap.

The actuators for two speed rear ends are dependable and robust. They survive for years near the road surface on the front of the differential.
Power on one wire (Ground return) drives the actuator to one extreme position. If the actuator is blocked mechanically, an internal spring is charged and the movement is completed when possible. Power on the other wire drives the actuator to the opposite position with the same spring loading feature. Limit switches disconnect the motor at each end of the stroke. A heat shield along with the air movement from road speed should keep the unit cool enough.
Spend a few hours or days Googleing auto parts sites to find a suitable model.
