System of production of the fulfilled gases

General information

L models 2.0 and 2.5

Design of system of production of the fulfilled gases (l models 2.0 and 2.5 with OBD II)

1 — the Right reception pipe
2 — the Left reception pipe
3 — the Forward catalytic converter
4 — Dokatalitichesky a lambda probe
5 — Post-catalytic a lambda probe

6 — the Central pipe
7 — the Back catalytic converter
8 — the Resonator
9 — Back section
10 — the Muffler


Design of system of production of the fulfilled gases (l models 2.0 and 2.5 about OBD Subaru equipped with the catalytic converter)

1 — the Right reception pipe
2 — the Left reception pipe
3 — the Forward catalytic converter
4 — the Lambda probe
5 — the Central pipe

6 — the Back catalytic converter
7 — the Resonator
8 — Back section
9 — the Muffler


Design of system of production of the fulfilled gases (l models 2.0 and 2.5 with OBD Subaru, without catalytic converter)

1 — the Right reception pipe
2 — the Left reception pipe
3 — the Central pipe

4 — the Resonator
5 — Back section
6 — the Muffler


On l models 2.0 and 2.5 the final path consists of assembly of reception pipes, catalytic converters (at the corresponding complete set), the central pipe, back section and the muffler. The forward catalytic converter fastens directly to reception assembly, back is built in in back part of the central section. For the purpose of decrease in level of a noise background the point of connection of reception pipes of forward section of system of release is located on equal removal from final ports of the engine, and in back part of system, besides the 16-liter muffler resonators (on latest models of 2.5 l resonators equipped also both reception pipes) are installed.

Models of 3.0 l

Design of system of production of the fulfilled gases (model of 3.0 l)

1 — Right dokataliticheskiya a lambda probe
2 — Left dokataliticheskiya a lambda probe
3 — the Right reception pipe
4 — the Left reception pipe
5 — the Right forward catalytic converter
6 — the Left forward catalytic converter

7 — the Back catalytic converter
8 — Post-catalytic a lambda probe
9 — the Resonator
10 — Back section
11 — the Muffler


Muffler design with the variable direction of a stream

1 — Small turns of the engine

2 — High turns of the engine


The design of system of production of the fulfilled gases is presented on an illustration.

Distinctive feature of system of release on models of 3.0 l is use of the muffler equipped with the special valve switch with the variable direction of the stream considerably reducing the level of the noise background published by the engine.
