Pacemaker 2.5" Performance Cat-Back Exhaust System for Ford Mustang GT Coupe (5.0L Coyote V8) - PP4178-01

Unleash a deep, aggressive American muscle growl and optimize gas flow velocity from your high-revving quad-cam engine with the Pacemaker Sport Systems heavy-duty 2.5" performance cat-back exhaust solution. Specifically engineered to maximize scavenging efficiency and enhance the distinct mid-to-high RPM acoustics of the iconic 5.0L Coyote V8, this premium system is precision-molded to clear the floor pan lines, underbody layout, and multi-link independent rear suspension geometry of the S550 Fastback platform. By replacing your stock, restrictive factory piping with a high-flow 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 high-load highway drone. Note: Fits Ford Mustang GT S550 Fastback Coupe models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; engineered 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 Cat-Back Section: Complete performance intermediate plumbing and rear muffler layout engineered to bolt up securely behind your factory or high-flow catalytic converters.
  • 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 2.5" (63.5mm) 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 sports coupes 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.

Important Fitment Notes:

  • Specifically engineered to fit Ford Mustang S550 GT Fastback Coupe platforms powered by the 5.0L Coyote V8 engine configuration (2015–2017 models).
  • Coupe Specific Chassis Layout: This configuration features tailor-formed exhaust pipe paths and bracket placements designed precisely to mount cleanly under the standard fastback coupe floor pan lines. It will not adapt correctly to Convertible models due to structural under-car cross bracing on the soft-top platforms.
  • 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 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 welding layout mapping is required.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, strict alignment, and gas-tight seals under the floor pan.

heavenly.

UGH, i'm so obsessed with these pillows!! they're so comfortable, adjustable, AND perfect in general. they're so fluffy when you get them, but you can take out as much of the memory foam as you'd want. what i really like about these pillows is, the ability to unzip the pillow & wash when desired (please read the instructions!) 💫. i sleep a lottt better compared to my other pillows, i highly recommend to get you some of these 🙂‍↕️✨✨. i'm not sure about a "cooling effect" since i have a pillow case over them, but they stay a neutral temperature where it's comfortable. i'm definitely going to back soon to buy the body pillow and a case (or two!) to revive old pillows (which i also love!). they come in a pair, so it's HIGHLY worth it, get them rnnn!!

Shocked
Color: White, Size: Queen (Pack of 2)
I'm really bougie when it comes to pillows. I've never spent less than $50 on a pillow. I'm a side sleeper and like firm support, but also want something soft. I almost ordered the really pricey pillows on Amazon, but was turned off by all the odor complaints. I needed something quick to at least hold me over until I could get exactly what I want, so I took a shot with this pillow with the plan of it being a temporary fix. However, this pillow turned out to be exactly what I was looking for. The first time I laid on it I was skeptical. It had support, but felt like it may have been too soft. It took a bit to get accustomed to, but by the second night I knew this is the pillow. No chemical odors, it's quality at a low cost. I figured this pillow would've been quickly replaced and put into the leg pillow rotation, but it is shockingly a really great pillow. It is not lumpy, stays way cooler than standard or shredded memory foam and is comfy. Hopefully it holds up for a long time. I've paid triple what these 2 pillows cost for a single pillow that isn't as good.

These pillows are amazing! They are huge and plush but you can change that if you prefer. I really like that the outside cover can be washed and is also filled. It held up great in the washer and dryer. I just followed the directions on the tag. Great price for the quality and look very nice and fluffed on the bed.

Good option
Color: White, Size: Body(Pack of 1)
I’ve been using the ACCURATEX Full Body Pillow for Adults – Hybrid Shredded Memory Foam for a few weeks now, and overall I’m really happy with it. The blend of shredded memory foam gives it a firm, supportive feel, but what I love most is that you can adjust the filling to get the exact firmness you want. Whether you prefer something more structured or slightly softer, it’s easy to customize by adding or removing foam. Comfort-wise, it’s definitely a step up from standard body pillows. It keeps its shape throughout the night and offers great support for side sleeping. That said, it is a bit firmer out of the box than I expected, which is why I’m giving it 4 stars instead of 5. If you’re looking for a body pillow that won’t go flat and lets you tweak the feel to your liking, this one is a solid choice.

Favorite pillow!!
Color: White, Size: Body(Pack of 1)
I honestly wasn’t expecting to love this pillow as much as I do. Buying pillows online always feels risky because you can’t actually feel them beforehand, but this ended up being one of the best blind buys I’ve made on Amazon. The quality is genuinely shocking for the price. It feels way more expensive than it is. It’s insanely comfortable, supportive without feeling stiff, and just has that “perfect” cozy feel. I have neck problems, so I’m really picky about pillows, and this one somehow manages to be the perfect balance. It’s supportive without being stiff or overstuffed, but also not too flat where your neck feels unsupported. It has that perfect “sink in but still supportive” feel that’s hard to find. I loved the body pillow version so much that less than a week later I’m already ordering the regular pillow version too. Easily 5 stars from me!!
