Pacemaker Full Twin 2.5" Performance Exhaust System with Headers & Hi-Flow Cats for Ford Mustang GT Convertible (5.0L Coyote V8) - PP4178-04

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 scavenging efficiency, optimize exhaust gas velocity, and satisfy the unique chassis configurations of the iconic S550 platform, this premium system is precisely shaped to map the specific structural underbody bracing lines of the factory Ford Mustang Convertible. 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 typical of convertible cabins. Note: Fits Right-Hand Drive (RHD) Ford Mustang GT Convertible models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; does not fit Fastback models due to convertible-specific chassis reinforcement paths.

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 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.
  • 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 lines.
  • 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 optimize exhaust gas tracking.
  • V-Tex Technology: Advanced internal patented anti-drone configuration cancels out harsh, low-frequency cabin resonance typical of open-air convertibles 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 layout components.

Important Fitment Notes:

  • Convertible Specific Layout Constraints: Mustang Convertibles feature extensive cross-bracing under the vehicle center floor pan to maintain structural rigidity. This kit features specific piping bends and modified intermediate paths to completely clear these factory braces without rubbing or floor vibration. It will not align properly with standard Fastback variants.
  • Right-Hand Drive Only: Header primary routing is exclusively mapped to navigate around standard factory RHD steering gear configurations. 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, intermediate twin 2.5" tubing, and signature double-skinned rear twin mufflers.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance around convertible bracing, correct steering link alignment, and strict gas-tight seals.

Still in one piece and played with!
Color: Checkers - Dinos Bruto (Purple), Size: Mini
Very durable for my little King Charles Chewer. She's had it for a while now and all though the chewing phase has calmed down, she still can be somewhat rough with the toys. The little dino is standing firm. It was a battle she figured she couldn't win with Dino. Now he's a fetch/ tug o war toy that still gets a few nibbles.

DONT BUY THE ELEPHANT, ITS NO GOOD. but GR8 BRAND!
Color: Checkers - Elephant (Gray), Size: Large
The elephant toy had no trunk by the FIRST day! The elephant now looks like an angry Koala bear OR an angry trunk less elephant(whichever u want to say) I LOVE the donkey and dinosaur toys so I bought the elephant confidently, thinking I had nothing to worry about. I wouldn't have spent money on this knowing the trunk would be chewed off in a matter of minutes. My Bella usually chews but she has had her donkey and dinosaurs with the chew guard for MONTHS and there are NO TEARS OR RIPS even with her playing and chewing on them ROUGHLY all day. If you buy any of these type toys I DO highly recommend the donkey or dinosaurs ONLY. The elephant being chewed up in a matter of minutes really makes me angry that I ever spent the money on it. HAD I known it wouldn't be the high quality dog toy I'm used to from GoDog, I would've just bought a second donkey or dino! Now Bella doesn't get her new toy for the month (I try 2 buy her a new stuffed toy or 2 about 1 time a month whenever I have the extra money for it) I guess she will have to go without this month because I spent it on this now trunkless elephant/angry koala:( Whichever name you call it, it is now going to be trash. UPDATE! If you contact the GODOG company they will send one replacement toy for your pet! They also asked me my pet's size, breed and age in order to send the best possible toy! They sent Bella a snake that has held up Extremely WELL! It's great and so far is my favorite(and one of Bella's favorites) The snake has less sqeaky things in it so she doesn't have the drsire to tear it apart immediately to retrieve them by rippong it to shreds:) My updated rating is for the MANUFACTURER'S GREAT CUSTOMER SERVICE. The fact that they actually replaced it was good but the fact that they went that extra mile by researching the best toy match for my Bella was above and beyond! If you have a Godog toy that went bust right away, contact the manufacturer for a replacement. If you give them your dog's age, weight and breed they will even try to match your pets replacement toy with something that is better suited to your dog's chewing style. (Bella's style is destructive haha) Good luck, ya'll!

My Dobermans favorite toy to destroy, and one of our recommended picks.
Color: Checkers - Elephant (Gray), Size: Large
Ok, here's an honest breakdown review. I have a 6 month old Doberman who shreds every stuffed animal and dog bed he's come across. He's one of the worst chewers I've owned. We have tried a WIDE variety of stuffed toys. That said, this elephant is his favorite toy. I have ordered 4 of them so far, and just ordered another 4-pack on a buy three get one free deal. The elephant stands out above all the other stuffed creatures from goDog for me as to durability. Hence why I keep buying more. But they usually last about 2-3 weeks on average. In our house, the poor creatures are subjected to vicious, crazy, shaking of the head, helicopter type rotation. It' so hard if it hits your bare arm or leg it actually stings especially when its wet. Then the old, put it between his legs laying down, tearing at the legs action. The limbs are usually the first things to go over time. But they are each almost self sealing, so you clean up as little fluff and keep using it. Eventually the pup reaches the main body and finishes it off. For a normal light to normal chewer, one of two will get you a long way. For those of us resigned to having zoomie type manic chewers that need a constant supply of toys, 2-3 week durability is pretty sound too. I do not recommend the green cheaper monster. It lasted about 45 minutes. The free replacement took about 3 days. Hopefully this aids you in your decision!

Very durable for rowdy pups
Color: Checkers - Elephant (Gray), Size: Large
This toy has outlasted any other dog toy I have ever bought. I have one large and one medium dog who share toys, fight over toys, chew them to death and still play with them. It might be because it isn't one of their favorites. I don't know. All I know is that our house is littered with dog toys in different states of destruction and this elephant toy has very little damage. It has definitely been in the dog toy rotation. I had this toy for 2 months without any major damage. The day I wrote the review the dogs tore the leg off! I still think it is a good toy. Some toys lose the stuffing or squeaker the first day.
