Note: Fits HSV VY Series 2 and VZ Sedan models (2003–2006) equipped with the 5.7L LS1 V8 engine.

Precision-manufactured in Australia to deliver the absolute peak in flow efficiency, heavy-duty scavenging, and raw acoustic output for the high-performance HSV sedan platform.

  • Complete Headers Setup: Total kit featuring 1 3/4" primary tuned headers, 3" hi-flow cats, and active piping sections.
  • Rear Pipe Configuration: Built with a straight-through rear pipe replacing the standard tail muffler for maximum exhaust bark and unrestricted flow potential.

The Best "Stock Up and Save" Find on the Internet! ⭐⭐⭐⭐⭐
Size: 7.5 Fl Oz (Pack of 6), Scent: Fresh, Size: 7.5 Fl Oz (Pack of 6), Scent: Fresh
If you are tired of overpaying for fancy hand soaps that run out in a week, this Amazon Basics 6-pack of Liquid Hand Soap is the ultimate household hack. It’s simple, effective, and honestly, a total steal. Why this 6-pack is a total winner: The "Original Fresh" Scent: It’s exactly what you want in a hand soap—clean, light, and crisp. It’s not overpowering or flowery; it just smells like a freshly cleaned house. Gentle on Hands: I wash my hands a lot throughout the day, and this formula doesn’t leave my skin feeling dry or cracked. It lathers up perfectly and rinses off clean without that weird "filmy" feeling some cheap soaps have. The Perfect Size: The 7.5 fl oz bottles are the ideal "goldilocks" size. They fit on every sink—from the tiny powder room to the cluttered kitchen counter—without taking up too much space. Bulk Convenience: Buying the 6-pack means I’m not constantly adding soap to my grocery list. I keep one at every sink and have backups ready in the pantry. No more "emergency runs" to the store when a bottle runs dry! The Bottom Line: You don’t need to spend $5 a bottle for clean hands. This Amazon Basics soap does the job perfectly, smells great, and saves you a ton of money over time. It’s a boring purchase that makes life so much easier. Final Verdict: 10/10. Great lather, great scent, and even better price. I’m officially a convert!

My Favorite Face Mask for Hydrated, Glowing Skin
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried a lot of face masks over the years, but the BIODANCE Bio-Collagen Real Deep Mask has easily become my favorite. Every time I use it, my skin feels incredibly hydrated, smooth, and refreshed, and the results last much longer than I expected from a single mask treatment. One of the things I love most about this mask is how deeply moisturizing it is. After wearing it overnight, my skin looks noticeably plumper and feels soft and nourished. Instead of just giving a temporary boost, I’ve found that the healthy glow lasts well beyond the next day. In my experience, my skin maintained a radiant, hydrated appearance for nearly two weeks after use, which is something I haven’t experienced with many other masks. The hydrogel material feels comfortable on the skin and stays in place well throughout the night. When I remove it in the morning, my skin looks brighter, more refreshed, and noticeably more hydrated. I appreciate that this mask feels like a true self-care treatment rather than just another skincare step. Whether I’m preparing for a special event or simply giving my skin some extra attention, this is the mask I consistently reach for. The fact that it comes in a multi-pack makes it even better because I always like having one available when my skin needs a boost. Overall, this is one of the few skincare products that I continue to repurchase because I genuinely notice a difference. If you’re looking for a mask that delivers intense hydration, plumping benefits, and a beautiful long-lasting glow, I highly recommend giving this one a try.I’m

Instant Glass Skin!
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried SO many sheet masks and this collagen one is genuinely one of the best. My skin looked insanely hydrated, smooth, and glowy after just one use. It fit my face really well, stayed soaked the entire time, and didn’t leave that sticky feeling afterward. The next morning my skin still felt soft and looked brighter. Perfect before events or whenever your skin needs a reset. Definitely repurchasing!!

Absolutely amazing masks!!!
Scent: Collagen, Size: 4 Count (Pack of 1)
These masks are beyond amazing! I use one once a week and leave it on overnight after completing my p.m. skincare routine and wake up to smooth, plump, moisturized, and absolutely glowing!! I have extremely sensitive skin and eyes and these masks do not bother me at all. No burning in my eyes and no irritation of the skin. My deep wrinkles seem a lot less pronounced and some of my more fine lines almost disappear for 24 hours after using this mask. They are simple to use and adhere to the skin perfectly even after applying serums and moisturizers. Once the mask is completely absorbed and becomes clear it peels of the skin with ease. Based on the quality of these masks I am shocked by the low price, it is such a great value for your money. This Mask has become a staple in my skincare routine and I will continue to purchase these!!

instantly more hydrated + glowy skin
Scent: Collagen, Size: 4 Count (Pack of 1), Scent: Collagen, Size: 4 Count (Pack of 1)
I love this mask. It’s one of those products you can actually see a difference with right after using it. It really helps with: 1. Deep hydration – my skin feels plump and moisturized, not dry or tight 2. Smoother texture – it softens everything and makes my skin feel really smooth 3. Glow/brightness – gives that fresh, healthy glow without looking greasy How I use it: I apply it on clean skin (usually at night), leave it on as directed, and let it fully absorb before removing. I like using it when my skin feels dull or dry and want a quick reset. Overall, it’s super easy to use and makes my skin look more refreshed every time. Definitely a go-to for me.
