Can someone help me understand why the stock exhaust is like that if It isn't practical to stretch it?
Be careful not to compare these engines and exhausts to much to real vehicles. these nitro motors are much more suseptable to any change you make. I am not sure exactly how your motor and exhaust are mounted, but I know that it being in front is not unsafe. The point above yours is that trying to modify your exhaust by addind more header and pipe length will throw the motor tuning off. The design of "one piece" header and pipe combinations are very exact. Adding length can create uneven pressure in the system causing the tuning to be off.
As for the Ventilation, Have you cut holes for ventilation in your body's windshield?
