Pacemaker Full Twin 2.5" Performance Exhaust System with Headers & Hi-Flow Cats for Ford Mustang GT Coupe (5.0L Coyote V8) - PP4178-03
Unleash an uncompromised, aggressive American muscle roar and unlock substantial power gains from your high-revving quad-cam engine with the Pacemaker Sport Systems complete twin 2.5-inch performance exhaust solution. Specifically engineered to maximize cylinder scavenging, optimize exhaust gas velocity, and satisfy the tight architectural boundaries of the global S550 fastback platform, this premium system is precisely shaped to map the underbody layout and multi-link independent rear suspension geometry of the Ford Mustang Fastback Coupe. By upgrading your stock layout to race-proven performance extractors paired with mandrel-bent twin 2.5" plumbing and high-flow metallic catalytic converters, it maximizes exhaust gas scavenging to completely eliminate power-robbing backpressure under heavy acceleration. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, delivering a commanding, throaty performance bark on throttle while actively engineering out harsh, intrusive cabin boom or highway drone. Note: Fits Right-Hand Drive (RHD) Ford Mustang GT Fastback Coupe models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; does not fit Convertible models due to under-car structural cross-bracing paths unique to soft-tops.
Features:
Precision-manufactured in Australia to deliver a high-velocity flow upgrade, maximum structural longevity under intense heat, and a refined muscle car acoustic profile for the iconic RHD Mustang fastback platform.
- Complete Headers & Full System: Comprehensive track-and-street performance solution incorporating high-flow primary headers, 3" metallic high-flow catalytic converters, and a matching twin 2.5-inch performance cat-back system layout.
- Fastback Coupe Optimized: Custom engineered to clear the floor pan configurations, standard chassis tunnels, and factory hanger geometries of the fixed-roof fastback coupe layout.
- Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior resistance to thermal fatigue and rust.
- Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and maximize flow velocity.
- V-Tex Technology: Advanced internal patented anti-drone configuration cancels out harsh, low-frequency cabin resonance typical of sports coupes without restricting gas velocity.
- Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium case reinforcement, preventing case distortion and internal packing blowout under extreme load.
- Right-Hand Drive Optimized: Specifically mapped and cleared to fit Right-Hand Drive (RHD) configurations seamlessly around steering linkages and factory components.

- Coupe Specific Layout: This system features specific piping clearances and bracket mapping designed precisely to mount under the fastback coupe chassis path. It will not adapt cleanly to Convertible variants because it does not feature the necessary underbody relief routes to clear the additional soft-top chassis reinforcement cross-braces.
- Right-Hand Drive Only: Header primary routing and collector path geometry are exclusively mapped to navigate around standard factory RHD steering gears and engine bay constraints. Will not fit imported Left-Hand Drive (LHD) models.
- Full kit scope: Comprehensive track-and-street performance solution from engine block to rear exit, including tuned primary headers, high-flow metallic catalytic converters, twin 2.5" intermediate sections, and signature double-skinned rear twin mufflers with polished exit tips.
- Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, strict steering column alignment, and gas-tight seals under the floor pan.

Exactly what I wanted
This robo-vac works great! Most of the well known products in this category are full of crap that you don't need, or is even spying on you. I'm sorry, but my appliances don't need WIFI, camera's, mapping features and an internet connection to send them to... who??? This unit has everything you need and nothing you don't. I bought it because my dog is shedding like crazy and leaving my floor looking like it needs a haircut. The Eufy has done a great job of picking up ALL of the dog hair, dirt and small particles, and has yet to become clogged. The floor it is cleaning is a linoleum floor that has a low pile rug and it cleans both very well. The Eufy runs for well over an hour and one of the best things about it.... it is VERY quiet. Emptying the dust bin is super easy, and cleaning the filters is very easy as well. The Eufy comes with extra side brushes and an extra roller. I have not had to change any of them yet, but maintenance and cleaning of these items has been made very easy as well. It comes with a well thought out cleaning tool that makes cleaning easy. It has a cutter on it, similar to an envelope opener, that gets under hair that wraps around the roller and and slices it off. This is a problem with ANY vacuum that has a roller, and this tool works very well for this. To be honest, I wasn't sure what to expect at the price point, but the Eufy works better than the older I-robot I had some time ago and is far easier to maintain. The very first time it ran it was learning the room and did not make it back to the dock, but every use since, it has always gotten back and docked. If you want a robot vac that you can start with a remote or program a schedule in, without WIFI, camera's, and yet another app to install on your phone, I highly recommend the Eufy... you won't be disappointed.

The Silent, Obsessive Predator in the War on Filth: A Dispatch on the eufy L60
Size: eufy L60 SES (renewed)
Dateline: My Living Room Floor, a Battlefield of Invisible Grime, 1:30 AM. The house is quiet. The world is asleep. But in the darkness, a hunter stirs. It detaches itself from its charging dock with a soft, electronic whir, its single laser-eye pulsing with a cool, blue light. This is not a vacuum cleaner. This is the eufy L60, an autonomous, dirt-seeking assassin, and it is beginning its nightly patrol.
To call what this machine does "mapping" is a gross understatement. This is military-grade reconnaissance. On its maiden voyage, the L60 didn't just bumble around bumping into things. No, it conducted a systematic, laser-guided survey of my entire living space, rendering a perfect, eerily accurate floor plan on my phone. It knows the terrain. It has identified the chair legs, the table supports, the treacherous geography of the area rug. It has logged the coordinates of every obstacle. It is operating with a level of tactical awareness that would make a special forces operative blush.
And then, the hunt begins. With 5,000 Pascals of raw, unadulterated suction power, it doesn't just "pick up" dirt; it inhales it. It moves in straight, deliberate, overlapping lines, a methodical grid search that leaves no square inch un-scoured. Dust, crumbs, the detritus of a life lived with a certain amount of reckless abandon—all of it vanishes into its maw. And hair… good heavens, the hair. It attacks strands of human and pet hair with a special kind of ferocity, its "Hair Detangling Technology" acting like a tiny, internal machete, chopping the stuff up before it can choke the machinery. It is a savage and beautiful solution to an ancient and vexing problem.
But the true genius, the feature that elevates this from a clever gadget to a genuine domestic revolution, is the self-empty station. This monolith is not just a charger; it is the L60's base of operations. After its patrol is complete, the little predator dutifully returns to the dock. And then you hear it—a ferocious, ten-second roar, like a miniature jet engine firing up. That is the sound of every speck of filth the robot has collected being violently sucked from its belly into a sealed bag within the tower.
The result? You don't have to do a thing. For up to 60 days, this silent partnership continues. The robot hunts, it cleans, it reports back to its base, it unloads its grim bounty, and it prepares for the next mission. You are completely removed from the dirtiest part of the process.
This eufy L60 is not just an appliance; it's a quantum leap. It is a quiet, frighteningly intelligent, and ruthlessly efficient solution to the endless, soul-crushing war against domestic filth. It maps its battlefield with perfect precision, it hunts its prey with relentless power, and it handles its own dirty work. It is, without a doubt, the single greatest ally you could ever have in the quest for a clean floor. Absolutely amazing.

Waste of money
Size: eufy L60 SES (renewed)
This vacuum is a total let down. It cleans well enough however it has lost its network connection every month since I have owned it. Not only do I have to take 20 minutes to get it to finally reconnect, but it also wipes out the map that is stored. So I can’t clean until it re-maps the floor, I have to re-divide the rooms, and ultimately can’t clean for close to 2 hours when I need it most. Don’t waste your time with this unit unless you want to deal with network issues every month

Great Price, Great Quality, Save your money from other over priced Brands
I absolutely love this! Just as good as any of the more expensive brands! It has great cleaning abilities and is able to get in every corner and crevice. This quality is amazing and it has a mapping feature with a remote to set it up. Powerful suction, connects to the wifi easily and has a perfect spin rate so it doesn't miss a thing! My biggest issue is that I wasn't using it as much as I should! Make sure you set up a timer and it will take care of the rest!

Growing up with robots...
I'll spare you the obvious and only mention in passing that this is obviously a Roomba-wannabee. That aside, it turns out to be a pretty good R-wbee. Which is unsurprising since I combed through a couple of different comparison YouTube videos, both of which ranked this model near the top of their lists in the category of powerful vacuum robot on a budget.
This lil sucker is indeed quite effective. I only have a carpeted bedroom, so it doesn't wander much, but it easily traverses even the bulged or steeped edges of my old burber carpeting. Like any such device, if you're going to leave it unattended, you will need to clear away any cords or other small debris (anything up to about popcorn size will just get vacuumed). I empty mine every other time I use it, and it's rarely brimming over. The only problems I've encountered have always been some kind of cordage or wire or string getting wrapped around the spinning scrubber unit--easily corrected.
I'm very happy with the remote. I tend to use it mostly as a remote controlled vacuum device; ie, me lazily stalking behind it, using the remote to reverse it or to bring it back round for a second pass, til I'm satisfied. In addition to allowing N-S-E-W directions, you can also press and hold a direction button to make it speed up. You can also toggle between carpet and hardwood mode. The device charges pretty quickly and usually lets me get 2 to 3 large room sessions completed before displaying low battery.
I will note that my kitten was a mere 3 months old when I got this device and she has literally grown up with it. It long ago stopped frightening her and now she regards this device as a friend and playmate to such an extent that I had to move the charging dock from a floor corner to a low dresser drawer--because when I left it out in the open, my cat would always manage to depress the big GO button and send it off partially charged, destined to tangle up my charging cables and neckties. So if you plan on letting your cat grow up with this robot, take precautions.
I would definitely buy another one of these, and probably will. Recommended.
