Turbo Exhaust System Design

Some turbo back and header back systems replace stock catalytic converters with others having less flow.

Turbo exhaust system design.

Given the installed locations of the turbochargers custom formed exhaust pipes are required to route exhaust from the turbos to the remainder of the exhaust system. Turbo back systems are generally produced as aftermarket performance systems for cars with turbochargers. Fwiw i m an turbocharger development engineer for garrett engine boosting systems. With design we mean the entire system from the engine exit point the turbo outlet in most cases all the way to where the exhaust leaves the boat.

As most of you know the design of turbo exhaust systems runs counter to exhaust design for n a vehicles. Defining the acoustic profile and influencing the powerband exhaust design is a more dynamic science than stringing together a few pipes and tacking on some mufflers. A poorly designed exhaust system will affect both boost control and peak power in any case so a larger turbocharger is required in order to compensate for this. A performance exhaust system is a characterizing element for any internal combustion conveyance.

The turbo back or turbo back is the part of the exhaust system from the outlet of a turbocharger to the final vent to open air. N a cars utilize exhaust velocity not backpressure in the collector to aid in scavenging other cylinders during the blowdown process.
