A roll bar exhaust system [1000] is described for retrofitting vehicles such as a pickup truck [100]. Two vertical pipes [1100] have exhaust conduits [1110] running through them which exit through exhaust outlets [1180] at their top side. Diagonal supports [1300] attach to a cross bar [1500] or the vertical supports [1100]. The diagonal supports also attach to the bed [110] of the vehicle. Exhaust conduits [1110] attach to elbows [1010] then to the engine exhaust [150]. Exhaust is routed from the engine exhaust [150] through the elbows [1010] up the exhaust conduit [1110] and out of the exhaust outlet [1180]. Since this is designed to have significant strength, it doubles as a roll bar system preventing the cab [130] of truck [100] from crushing and injuring passengers in the event of a roll over.
