I am trying to install led's on the bottom of my old t-maxx, but the bottom of the chassis always gets exhaust oil on it from the stinger that sticks through the chassis and towards the ground. My dad says that I could get a pipe to redirect the exhaust to the back. Would I have to get a huge pipe so I don't mess up the exhaust system, or could I weld a pipe of a similar size to the stinger? Maybe I should just turn my pipe so the stinger aims out, but it would be cool to have a real working exhaust pipe.
