I am converting to side exhaust and while thinking about my options to cover the rear exhaust hole I am considering putting a piece of aluminum sheet extending from the stock plate under the transmission to the rear bumper fascia (mounted to the bottom of the frame).
I am hoping it will improve the air flow under the car and it will also give me something to attach a rear panel to fill the exhaust hole without drilling a bunch of holes in the bumper fascia.
Does anyone know if covering this area will reduce cooling to the differential that could potentially lead to early failure? Any other potential problems with doing this? Will drilling and tapping very small holes into the bottom of the frame to secure the aluminum cause any significant weakness in the frame?
Any insight into these questions would be appreciated.
