Pacemaker Full Twin 2.5" Performance Exhaust System with 1 3/4" 4-into-1 Tuned Headers & Hi-Flow Cats for HSV VE E-Series E2 Sedan (6.0L Gen IV LS2 V8) - PP5381-13
Unleash significant torque fields, optimize mid-to-high RPM cylinder scavenging, and deliver an aggressive, deep Australian V8 muscle note from your small-block engine with the Pacemaker Sport Systems complete twin 2.5-inch performance exhaust solution featuring 1 3/4" 4-into-1 tuned primary extractors. Meticulously engineered to balance optimal exhaust gas velocity tracking with excellent total volumetric flow, this 1 3/4" primary setup serves as the ideal high-efficiency configuration for standard to moderately modified or daily-driven street performance builds. Specifically configured for the high-performance 6.0L Gen IV LS2 V8 engine architecture, this premium full system is precision-molded to trace the sedan floor pan lines, clear standard wheelbase chassis channels, and map perfectly around the multi-link independent rear suspension geometry of the VE series HSV architecture. By upgrading your stock layout to high-flow 4-into-1 headers paired with smooth, mandrel-bent twin 2.5" plumbing and 3" high-flow metallic catalytic converters, it maximizes gas velocity tracking 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, producing an authoritative performance roar on throttle while actively engineering out harsh interior cabin boom or sedan body resonance to preserve a completely clean, drone-free highway cruising experience.
Note: Fits HSV VE E-Series E2 Sedan variants built from September 2009 to August 2010 equipped with the 6.0L Gen IV LS2 V8 engine layout; does not fit Utility (Ute), Sportwagon, or long-wheelbase Grange platforms due to structural floor pan and rear assembly differences.
Features:
Precision-manufactured in Australia to deliver a high-velocity flow upgrade, maximum structural longevity under intense heat, and a refined performance acoustic profile for the iconic VE sedan platform.
- Complete Performance Kit: Comprehensive track-and-street performance solution incorporating high-flow 1 3/4" 4-into-1 headers, 3" metallic high-flow catalytic converters, and a full matching twin 2.5-inch performance intermediate-to-rear exhaust layout.
- 1 3/4" 4-into-1 Design Architecture: Tuned extractor layout featuring high-velocity 1 3/4" primaries running into a merged collector to optimize mid-range torque retention and unlock seamless high-RPM power gains on street-driven applications.
- Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue under extreme loads.
- 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 prevent restriction.
- V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of sports layouts without creating any power-robbing flow restrictions.
- Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case reinforcement, preventing case distortion and internal packing blowout under heavy thermal load constraints.
- 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.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.

Quality product
Color: Navy, Size: 6-Quart
I absolutely LOVE my Dutch oven! The reduced cooking time for certain cuts of meat for stews, pot roast, etc., is a definite game changer!! The meat comes out so juicy and tender. I made curry and did the "burning" of the curry and was hesitant because I didn't want the pot to be stained. There were no stains left at all. I've used it numerous times since purchasing and it still looks new. It's very durable and the color is beautiful. If you're looking for a functional, quality, and durable Dutch oven without breaking the bank, this is it! I highly recommend.

Nothing Exceptional but Gets the Job Done
Color: Blue, Size: 4.3-Quart, Color: Blue, Size: 4.3-Quart
I’ve owned this 4.5 Qt. Amazon Enameled Cast Iron Dutch Oven for almost two months and have used it three times to date. Upon arrival and at first glance, the gradient blue color is beautiful and super glossy; most importantly, the pot is heavy for its size - as it should be. It looks exactly like the product pictures, with a globular shape than square shape as others. Unfortunately, I also noticed that there was one pin hole and two tiny uneven protrusions on the enamel inside the pot.
I own three other enameled cast iron cookware from two other brands (photos attached for size comparison) and performance wise, this cast iron by Amazon performs equally to them. The pot isn’t exceptional or special but it gets the job done. Other than the pin holes and protrusions, I have no complaints. This isn’t my first rodeo so when heating up the pot and while cooking, I have zero issues.
I am starting the pan off at 4-Stars and will update my review as time progresses, or if I have any major issues with its durability or performance in subsequent months. For the amateur home cook, or for anyone who is new to cast iron cooking, below I’ve included tips that you may find useful while using this or any other enameled cast iron cookware.
================================
Regarding the 3 Photos and 1 video I've Attached:

================================
TIPS THAT YOU MAY FIND USEFUL While Using your cast iron dutch oven:
(Note: I included these similar tips in my review of a different enameled cast iron pot from a different brand. My tips can apply to all enameled cast iron cookware)
1. If you find that you have issues with food sticking, it could be that you are not heating up your cast iron pot properly to prevent undue hot spots.
I heat my pot up gradually starting at low, then medium, then high heat. After my pot is very hot is when I add my fat/cooking oil. As the oil is heating up in the pot, I lift it and swirl the oil around to coat all sides of the pot that will come in contact with food.
2. Take into consideration the temperature of the items you are adding to your heated pot. As a general rule for cooking: when ever possible, ensure that the items you are adding to a hot pot are at room temperature, rather than ice cold from the fridge; this will assist with even cooking.
3. Also, get comfortable with adjusting your heat by lowering and raising it based on what you’ve added to the pot. In general, you will need more heat at the beginning of the cooking process, and less heat towards the end. If you cook by recipe, I highly recommend that you read all the steps ahead before starting, so that you become familiarized with all the procedures, allowing you to maneuver accordingly when you start cooking.
4. At the exception of searing meat to achieve a brown crust, deep frying, or when caramelizing onions, you should be stirring your pot (I recommend using a wooden spoon) every few minutes when cooking in cast iron that is placed over high heat. If you are braising on the stove at low heat versus braising in the oven, the frequency of your stirring will need to be adjusted. No matter how you’re cooking though, a watchful eye on the pot plus stirring, should both be a habit not an afterthought.
5. For all cooking vessels in general but especially for cast iron: after cooking, allow your pot to cool down completely before cleaning. NEVER immerse a hot cast iron pot into cold water, nor pour cold dish water into hot pot. You risk not only being scald by dangerous steam, but you also risk weakening the enamel, therefore lessening the durability of your pots over time.
6. This cookware and others like it from Tramontina and Lodge are economical and if used correctly, will perform well for most cooking; if used correctly, they should also last for years. Nonetheless, if you can afford it, authentic enameled cast iron cookware made in France by Le Creuset is the best way to go. Le Creuset is the gold standard in cast iron cookware and their quality is second to none. I definitely recommend this Amazon dutch oven but if you can afford to splurge, Le Creuset's reputation is stellar. As a professional chef, I've used them in high end kitchens and their quality and performance is premier.

Nice BIG enameled cast iron dutch oven. like LeCreuset but costs less
Color: Blue, Size: 6-Quart
This is nice quality, similar to the far more costly French LeCreuset brand. I was surprised how big this model is, possibly too big for my small kitchen and limited storage space. I store it in the oven. It would be great for baking sourdough boule bread.
