Chevrolet and GMC School Bus Exhaust Parts

Express, Savana, G-Series, Kodiak, and TopKick

Auto-jet manufactures Chevrolet and GMC school bus exhaust parts for cutaway van chassis and conventional chassis. GM builds the chassis and a separate company builds the bus body, so fitment depends on both. Confirm the chassis and the body builder before ordering.

Chevrolet and GMC School Bus Exhaust Parts by Chassis

Cutaway vans cover the Chevrolet Express, GMC Savana, G-Series and G-3500, with 350 C.I., 4.8L and 6.0L gas, 6.5L turbo diesel, and 6.6L Duramax engines. Bodies on these chassis come from Thomas Minotour, Corbeil, Girardin, Micro Bird and Berlin.

Conventional chassis cover the GMC B7, Kodiak and TopKick, with 366 and 427 C.I. gas, 454 and 502 C.I. gas, 6.5L turbo diesel, and Caterpillar 3116 and 3126 engines. Blue Bird CV200 and Mid-Bus bodies use these chassis.

Van tailpipe extensions vary by body builder, not by chassis. Two buses on the same GM chassis can need different extensions depending on who built the body. Auto-jet lists made-to-length extensions for applications the printed pages do not cover.
