Abstract
An integral exhaust pipe and mounting bracket for use with the engine exhaust system of medium or heavy duty trucks which have a structural framework. A mounting plate is secured to one end of the exhaust pipe and mounted to the structural framework of the truck. The opposite end of the exhaust pipe is oriented generally vertically generally parallel to the wall of the truck cab but otherwise free standing. A lateral brace bridges the mounting plate and the opposite end and is secured therebetween. The exhaust pipe, mounting plate and lateral brace complete the integral mounting bracket with the exhaust pipe being utilized as a structural member instead of being a nonstructural mass attached to a bracket and supported as a dead weight thereon.
