Exhaust X-Pipe for Maserati Ghibli Base & S (2014-2023)

High-Flow Resonator Delete X-Pipe for 2014-2023 Maserati Ghibli (F160 / M156)

What it Does: Replaces the restrictive, heavy factory center resonator with a precision crossover X-pipe to balance exhaust pulses and enhance the acoustic profile of the Twin-Turbo V6.

The Stock Ghibli Exhaust Bottleneck

The factory M156 exhaust system utilizes a large-volume center resonator designed primarily for sound suppression and NVH (Noise, Vibration, and Harshness) reduction. This OEM component creates a significant point of turbulence where exhaust gases from the two cylinder banks expand and collide non-linearly. From a fluid dynamics standpoint, this creates unnecessary backpressure that can impede exhaust velocity and retain heat near the transmission tunnel. The stock baffles effectively muffle the high-frequency characteristics of the Ferrari-developed F160 engine, resulting in a muted exhaust note that fails to reflect the vehicle's performance capabilities.

The Engineering Solution

This URUTU Exhaust X-pipe is engineered to optimize scavenging by equalizing the pressure between the left and right exhaust banks. By facilitating a smooth crossover point, the X-pipe utilizes the velocity of one exhaust pulse to help pull the subsequent pulse from the opposite bank, reducing parasitic pumping losses. Constructed for high-thermal resistance, the kit includes two 2.5" and two 2.75" heavy-duty clamps to ensure a gas-tight seal at the factory connection points. This resonator eliminator reduces overall curb weight and provides a more aggressive, crisp European tone without the drone or rasp often associated with straight-pipe modifications. The geometry is specifically tuned for the RWD hanger configuration to ensure a direct-fit replacement.

Technical Specifications

Compatibility

• 2014-2023 Maserati Ghibli Base Model (Rear-Wheel Drive)
• 2014-2023 Maserati Ghibli S (Rear-Wheel Drive)
