Pacemaker 2.5" Performance Exhaust System with 1 3/4" Tuned Headers & Rear Pipe Only for Holden VT, VX & VY Series 1 Sedan (5.7L V8) - PP5361-08

Unlock major horsepower gains and unleash an ultra-aggressive muscle roar from your 5.7L LS1 engine with the Pacemaker Sport Systems complete performance exhaust solution. Specifically engineered for the Holden VT, VX, and VY Series 1 Sedan platforms, this high-flow setup replaces the standard rear tail muffler assembly with an unrestricted, straight-through "Rear Pipe Only" section. Featuring 1 3/4" primary tuned headers paired with a balanced twin 2.5" mandrel-bent line, it delivers maximum exhaust gas velocity while providing an unfiltered racetrack bark. It is the ultimate match for cammed, modified, or high-scavenging 5.7L builds that demand peak track-day performance and an intense sound profile. Note: Fits Holden VT, VX, and VY Series 1 Sedan models (1999–2003) equipped with the 5.7L LS1 V8 engine.

Features:

Precision-manufactured in Australia to deliver the absolute peak in flow efficiency, heavy-duty scavenging, and raw acoustic output for the VT-VY Commodore 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.
  • 1 3/4" Tuned Headers: Proven primary tube design engineered to optimize mid-to-high end power potential and volumetric efficiency.
  • Premium Materials: Constructed completely from durable Exhaust Grade 409 Stainless Steel for superior longevity under high thermal stress.
  • Mandrel Bent Tubing: Heavy-duty twin 2.5" (63.5mm) pipe structure ensures a smooth, constant internal diameter to prevent backpressure.
  • Hi-Flow Cats: Supplied with 3" premium high-flow metallic catalytic converters transitioning cleanly to a high-velocity 2.5" path.

The best lower unit gear oil I have used
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
I have been boating my whole life, this is by far the best gear oil. I use this in my Johnson 115 even though this is technically made by Mercury. I seem to get less if any water intrusion into my gearcase with this oil. If there is any, the oil emulsifies the water and continues to protect the gears. I have had better luck with this than Pennzoil marine or others. Highly recommend. It is a blue color and easy to drain and fill.

Does not come with a pump.
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
The Good: Changing the fluid in the lower unit is a very easy DIY job. This can save you hundreds of dollars each year by doing it yourself. The Bad: You need a special pump to change the oil, and sometimes it comes with the gear lube. Unfortunately this product did not come with it. Luckily my neighbor had an extra one from changing the lube a different boat laying around and was able to use that. The Ugly: If you have to go get the pump, that could cost a few extra dollar but is just an extra nuisance. The pumps are interchangable but you just need to clean it between uses (DON'T MIX DIFFERENT OIL BRANDS)
