Product Description
A Return to Form, Refined
The GrimmSpeed Gentleman’s Exhaust returns with a redesigned Version 2 layout focused on fitment, longevity, and maintaining a clean, refined exhaust note. Built around the original “gentleman’s exhaust” concept, this system delivers a balanced tone that avoids drone while still providing a strong, confident presence.
Key updates include dual-overlapping slip fit connections and a revised dual-hanger mid-pipe, allowing for greater adjustability during installation and more precise alignment on a per-chassis basis. Internally, the upgraded muffler design features larger perforated cores and an improved Y-splitter to increase flow, paired with a durable packing configuration that resists breakdown over time.
The resonated version is ideal for drivers planning additional exhaust modifications. It helps maintain a smoother, more controlled sound profile as airflow increases throughout the system, making it the better choice for more heavily modified setups.
