Key Features
- Genuine OEM Exhaust Integrity — Manufactured to the original exhaust system specification for the QSL9-G2, ensuring correct flow geometry and acoustic attenuation at the catalyst inlet stage.
- Direct Bolt-On Replacement — Engineered to match the original mounting and connection points on QSL9-G2 studio generators, so installation follows the standard service procedure without adaptation.
- Confirmed QSL9-G2 Fitment — Specifically validated for Multiquip QSL9-G2 studio generator applications — check your model code before ordering to ensure compatibility.
- Exhaust Flow and Emissions Control — A correctly functioning catalyst inlet silencer directs exhaust gases into the aftertreatment system at the proper pressure and temperature, supporting both noise reduction and emissions compliance.
- Emissions System Compliance — As part of the exhaust aftertreatment circuit, using the correct OEM silencer helps maintain the generator's designed emissions performance and regulatory compliance.
The catalyst inlet silencer is a critical junction component in the exhaust aftertreatment system of the Cummins QSL9-G2 engine. It channels exhaust gases from the engine outlet into the catalytic converter while simultaneously attenuating noise generated by exhaust pulses — a function that matters both for sound level compliance and for protecting downstream aftertreatment components from pressure irregularities. When this component is damaged, cracked, or improperly sealed, exhaust gases can leak before reaching the catalyst, degrading emissions performance, increasing noise output, and potentially exposing personnel to exhaust fumes in enclosed or semi-enclosed generator installations.
