XForce LS1 V8 Header & Metallic Cat Kit - Holden VT-VZ - H2-HV12B-KIT
Upgrade your LS1 V8 performance with the Xforce Header and Cat Kit. Crafted from durable 201-grade stainless steel, this kit is specifically engineered to optimize exhaust scavenging and flow for the 5.7L Gen III engine. It features a high-performance 4-into-1 design with 1 5/8" primary pipes collecting into a 2.5" outlet.
The kit includes 2.5" metallic high-flow 100-cell catalytic converters, providing a significant reduction in backpressure compared to factory units. This combination delivers improved torque, increased horsepower, and the deep, aggressive V8 growl that Xforce is famous for. Designed as a modular upgrade, this kit is intended to bolt directly to Xforce cat-back exhaust systems for a complete performance solution.

- 1x Pair of 4-into-1 Headers (1 5/8" Primaries)
- 2x 2.5" Metallic High-Flow 100-Cell Catalytic Converters
- Gasket and Bolt Kit for Header-to-Cat connection
Features:
- 4-into-1 Design: 1 5/8" primary pipes for balanced flow and improved mid-range torque.

- 201 Grade Stainless Steel: Non-polished finish for heavy-duty durability.
- RWD Compatibility: Specifically suits VT-VZ LS1 RWD sedan, ute, and wagon variants.
- Performance Ready: Designed to integrate seamlessly with Xforce cat-back systems.

Offers Complete Privacy
Color: Black, Size: 132in-Large Metal Base
We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.

Not 6 ft
Color: Grey, Size: 34" - 3 Panel
I bought this for filming my auditions. I am 5’4” .The height lists is 6 ft but the fabric only reaches 5’9 1/2 “!
when I must film myself head to toe, the top bars are showing. It’s easy to set up. But when I film I must tilt my camera to keep the top bars out of frame which is not acceptable.

Perfect for what I needed - getting a 2nd one.
Color: Black, Size: 22" - 4 Panel
Putting it together was a BEE-OTCH!! Yes, one of the tubes had the top cap installed at the wrong end (& getting it off required tools), and yes, stretching the fabric to get the screws in was incredibly hard...but am I buying another one? YES! After all is said and done, this is a great room divider. I opted out of installing the paddle feet & it still works perfect. It won't filter light all that great and even though it stands on its own, it can be blown over easily - but for the price? Excellent. If I wanted a heavy duty, thicker, more expensive one, I would've bought one.
The 2nd one is on the way.
Perfect height, no weird smell, nice and light and easy to move around.

WHERE HAVE YOU BEEN 😊
Color: Grey, Size: 34" - 3 Panel
I purchased RANTILA 3 Panel Room Divider, 6 Ft Tall Folding Privacy Screen Freestanding Room Partition Wall Dividers, 102''W x 20''D x 71''H, Grey. For outdoor use on my patio is perfect . PRIVACY!!! YAY!
It was packaged very carefully. There were no missing parts. Instructions were there but I still had to use the video visually. A few screws would not screw in. So I used a hammer with a few good taps that helped using the screw driver. 😊 It was easy putting it together following the directions. Everything is well made. Love the height, functionality and it’s definitely light it works.
Thank you
