Turbo Exhaust System Design

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.

Turbo exhaust system design.

A performance exhaust system is a characterizing element for any internal combustion conveyance. Some turbo back and header back systems replace stock catalytic converters with others having less flow. 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. 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.

Turbo back systems are generally produced as aftermarket performance systems for cars with turbochargers. As most of you know the design of turbo exhaust systems runs counter to exhaust design for n a vehicles. N a cars utilize exhaust velocity not backpressure in the collector to aid in scavenging other cylinders during the blowdown process. Not to mention the poorly designed exhaust system will cause unwanted turbo lag meaning an unresponsive and unexciting driving experience.

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. This is an example of a twin turbo system fitted to an ls7 engine which increases rear wheel horsepower to 1 000 under full boost.
