How does the twin-inlet design affect performance and noise?

The twin-inlet layout helps the muffler manage exhaust pulses from small-displacement engines, smoothing flow and helping reduce audible noise. While not a power-increasing upgrade, it restores intended exhaust routing and reduces disruptive sound when compared to a damaged or rusty original muffler.

• Twin inlets align with factory exhaust ports for proper flow.
• Internal chambers and baffles reduce harsh exhaust frequencies.
• Replaces failed mufflers that create excess vibration and noise.
