Boost the torque and efficiency of your diesel powerplant with the Pacemaker PH 12581 Tri-Y Performance Headers. Custom-engineered for the Toyota Hilux and 4Runner 3.0 Litre Diesel models from 2003 onwards, these headers are specifically designed to accommodate vehicles equipped with EGR (Exhaust Gas Recirculation) systems. The Tri-Y design focuses on improving exhaust scavenging, which is essential for diesel engines to maintain low-end grunt and better fuel economy during towing or off-road driving. Constructed with 1⅝" (41mm) primary pipes and 1⅞" (48mm) secondaries, this kit provides a significant flow improvement over stock manifolds, terminating in a 2¼" (57mm) outlet for optimal backpressure management.

  • Tri-Y Scavenging: Optimized pipe routing to maximize low-to-mid range torque, perfect for 4WD applications.
  • EGR Compatible: Features the necessary provisions to retain the factory EGR system for emissions compliance.
  • High-Flow Mandrel Bends: 1⅝" (41mm) primaries and 1⅞" (48mm) secondaries ensure smooth, unrestricted exhaust gas velocity.
  • Heavy Duty Construction: Built to withstand the high heat and vibration levels common in diesel engines.
  • Full Accessory Clearance: Engineered to fit seamlessly with Power Steering and Air Conditioning systems.
  • Precision Fitting: Designed specifically for Manual transmission 4WD models for a bolt-on experience.

Hole after 3 times wearing them
Color: Cream Beige, Size: Medium
While these fit well and stayed up, after three times wearing one of them has a hole in it already. Not worth the money

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!
