Pacemaker Heavy-Duty 3" Performance Cat-Back Exhaust System for Ford Mustang GT Convertible (5.0L Coyote V8) - PP4178-52

Unleash a deep, aggressive American muscle growl and unlock massive flow capacity from your high-revving quad-cam engine with the Pacemaker Sport Systems heavy-duty large-bore 3" performance cat-back exhaust solution. Specifically engineered to maximize scavenging efficiency and satisfy the high-velocity gas volume demands of the iconic 5.0L Coyote V8, this premium system is precision-molded to clear the specific underbody bracing lines and structural layouts unique to the S550 soft-top architecture. By replacing your stock, restrictive factory plumbing with a high-volume mandrel-bent performance construction downstream of the catalytic converters, it optimizes gas velocity to clear spent exhaust out rapidly and completely eliminate power-robbing backpressure under acceleration. As Australia’s premium exhaust innovator, Pacemaker pairs this high-flow path with patented V-Tex technology and signature double-skinned mufflers to deliver a raw, thumping muscle car sound outside while actively engineering out harsh, intrusive interior cabin boom or open-air highway drone typical of convertible cabins. Note: Fits Ford Mustang GT S550 Convertible models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; engineered with optimized global clearance metrics to suit both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) configurations.

Features:

Precision-manufactured in Australia to deliver a premium flow upgrade, exceptional structural durability under high heat, and a refined performance acoustic profile for the global Mustang GT platform.

  • True 3" Cat-Back Section: Complete high-volume performance intermediate plumbing and rear muffler layout engineered to bolt up securely behind your factory or high-flow catalytic converters.
  • Convertible-Specific Clearances: Custom engineered to route flawlessly around the additional under-car chassis strengthening cross-bracing unique to the soft-top convertible floor pan.
  • Dual Drive Layout Compatible: Precision-cleared underbody routing architecture engineered explicitly to accommodate both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) chassis variations.
  • Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity under intense thermal stress.
  • Mandrel Bent Tubing: Rigid large-bore 3" (76.2mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to optimize exhaust gas velocity and prevent restriction.
  • V-Tex Technology: Advanced internal anti-drone configuration filters out harsh, low-frequency cabin resonance typical of open convertible cabins without creating any power-robbing flow restrictions.
  • Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case protection, zero internal packing blowout under high thermal stress, and precise tonal control.
  • Direct Bolt-On Layout: Engineered as a comprehensive, vehicle-specific full bolt-up kit that mounts directly onto existing factory rubber hanger positions—no custom fabrication required.

This kit features specific piping bends and modified intermediate paths to completely clear these factory braces without rubbing or vibrating.

  • Global Steering Compatibility: Underbody routing clearance metrics are optimized to seamlessly accommodate both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) export market models.
  • Full kit scope: Comprehensive high-flow large-bore 3" cat-back line including performance intermediate plumbing sections and a signature double-skinned rear muffler assembly with polished tips.
  • Direct bolt-on design reuses your vehicle's factory rubber hanger positions and standard catalytic converter paths. No custom fabrication or cutting layout mapping is required.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance around soft-top under braces, strict alignment, and gas-tight seals under the floor pan.

Exelent choice no more hinging cables
I recently purchased the EZ Outlet Electrical Outlet Extender, and it has been a total game-changer for my home. I have a few outlets behind furniture and in tight corners that are almost impossible to use, and this product solved that problem instantly. The extender itself feels very sturdy and well-made. The most useful feature is the flexible, gooseneck-like arm that lets you bend the outlet away from the wall. This allowed me to easily plug in my lamp and a few other devices that were previously unreachable. I also love the extra ports. The two regular AC outlets, a USB-A port, and a USB-C port are incredibly convenient. It's great to be able to charge my phone and my laptop from the same spot without needing a separate charging block. The USB-C port is particularly fast, which is a huge bonus. Setup was as easy as plugging it in. There's no complicated wiring or anything to deal with. It's a simple, elegant solution that works exactly as advertised. If you have any hard-to-reach outlets in your home, I highly recommend this product. It's well worth the investment.

Looks good, adjustability is super nice
This is attractive (for what it is) and is working well, I really like the adjustability - the only downside so far is that the USB ports are on the underside where I'm using it, so are basically unusable on a regular basis unless you want to leave a cable dangling from it, tho if you had it run up or to the right from the outlet, that wouldn't be a factor.

Its Quality
I absolutely love this! It’s a life changer for me as I’m always pulling the cord out from the wall in the attempt to stretch it. This now sits plug now sits perfectly between my bed and the wall. Excellent quality, easy to plug in and makes my life easier!

Nice length and looks good
Bought two different types/brands of outlet extenders, overall I like this better out of the two when it comes to looks and functionality. This one you plug it in then rotate the outlet to the spot you need. One adhesive pad holds it in place easily due to light weight and trim materials. You can still plug something else in the wall outlet, this only takes up one of the outlets. It would be great if they added usb plugs to this like the other one.
