The Maserati Quattroporte 2014+ consists of three main components: ① downpipe, ② Mid pipe, and ③Rear Exhaust.


For the diesel models, although the muffler layout is different, the muffler components remain the same.


It's also important to note that the muffler dimensions differ between 2WD and 4WD models.


At our company, we have developed products for all grades, including gasoline models, diesel models, and the 3.8L GTS, so you can rest assured.


First, let's look at the rear muffler, which is the most common part for achieving the high-pitched sound of the Maserati Quattroporte.

Our variable rear exhaust is designed to provide sharper valve switching than the OEM version. In straight mode, it uses a tube that is completely independent from the muffler to allow high-pitched sounds to burst at high RPMs.


We've meticulously calculated the design of the piping, punching inside the tube, and the placement of glass wool. This ensures that when the valve is off, the noise reduction level matches or even exceeds that of the OEM setup.

In addition to the rear exhaust, another key component for exhaust upgrades is theMid pipe. The stock center muffler is equipped with a large silencer and has many areas of exhaust interference. Removing these and converting it to a full straight design improves exhaust flow even further.


However, the most critical aspect when manufacturing a Mid pipe is the layout that enhances high-pitched sounds.


At our company, we offer two types of Mid pipe designs to ensure the optimal choice by considering the overall setup comprehensively:


1. Specification focused on achieving high-pitched, beautiful sounds and improving torque without excessively increasing volume.

2. Specification aimed at increasing volume while targeting high-pitched sounds, aiming to achieve a powerful sound reminiscent of Ferrari.


Lastly, playing a crucial role in achieving the high-pitched sound for the Ghibli is the straight downpipe.

The straight downpipe is recommended for those seeking increased volume and a broader range of high RPM sounds. For individuals who find replacing the rear and mid pipe insufficient, it represents a particularly impactful tuning option.


When prioritizing replacement based on effectiveness, both the downpipe and Mid pipe hold equal importance, while the rear exhaust takes a lower priority. This is because, even with the valve open, exhaust always passes through silencers and catalytic converters, which act as impediments.


Additionally, an often overlooked component in the market is the muffler tail finisher.
