Sport exhaust system 1 × 80 mm for Manta B-CC — TA Technix

A complete exhaust system replaces everything downstream of the catalytic converter. Its main effect is sound: less baffled silencers, a more pronounced low-end tone, and a sharper-sounding climb through the rev range. In terms of power, the gain does exist but remains modest on a stock engine, because the restriction in a production engine is mainly upstream - at the catalytic converter and downpipe.

The second effect, less often mentioned but more lasting: weight and durability. A stainless-steel system does not rust, can still be removed ten years from now, and weighs less than a standard aluminized-steel exhaust. On a car you intend to keep, it is the part you only fit once.
