Valved Rear Mufflers

Valved stainless steel rear mufflers for the Maserati Ghibli (2013+), covering Base, Q4 and V8 Trofeo models - fitment on the Hybrid hasn't been confirmed. They're designed to run alongside the factory resonated mid-pipe and give improved sound and power over stock. The valves are controlled through the factory Sport button, so you get full control over sound level without an aftermarket controller. Built from T304L stainless steel with a polished finish for durability and corrosion resistance, they come with quad-style tips in your choice of finish. Installation is a simple bolt-on job with no cutting or welding required.
Frequently asked
Does the Valved Rear Mufflers fit my Ghibli?
This listing is specific to the Maserati Ghibli. Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Will these fit my Ghibli Hybrid?
Fabspeed hasn't confirmed fitment on the Hybrid model, so check with them before ordering if you have a Hybrid.
Do these replace the mid-pipe too?
No, they're designed to be installed alongside the factory resonated mid-pipe, not in place of it.
How do I control the exhaust volume?
Through the car's factory Sport button - the valves in the mufflers open and close with it, so no extra controller is needed.
What tip finishes are available?
Quad-style tips in your choice of finish, either polished stainless steel or satin black.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
