Pacemaker Performance Twin 2.5" Cat-Back Exhaust System for HSV VE E-Series E3 Sedan (6.0L Gen IV LS2 V8) - PP5381-04

Maximize airflow efficiency, accelerate downstream gas velocity, and unlock a deep, commanding local muscle car roar from your high-performance powerplant with the Pacemaker Sport Systems complete twin 2.5-inch performance cat-back exhaust solution. Custom-engineered specifically to handle high gas volumes and optimize torque retention on the elite HSV E3 series 6.0L Gen IV LS2 V8 sedan platforms, this premium setup is precisely shaped to map the underbody floor pan lines, clear standard wheelbase chassis channels, and map perfectly around the multi-link independent rear suspension geometry. Designed explicitly to interface flawlessly with your vehicle's factory fixed exhaust tips integrated into the rear bumper fascia, this premium kit delivers seamless aesthetic alignment. By replacing your stock, restrictive factory plumbing downstream of the catalytic converters with smooth, mandrel-bent twin 2.5" plumbing, it completely obliterates system backpressure to deliver rapid acceleration and crisp throttle response. As Australia’s premium exhaust innovator, Pacemaker pairs this free-flowing layout with patented V-Tex technology and signature double-skinned mufflers, producing an authoritative performance bark under wide-open 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 E3 Sedan variants built from September 2010 to March 2013 equipped with the Gen IV 6.0L LS2 V8 engine layout and factory fixed bumper exhaust tips; does not fit Utility (Ute), Sportwagon, or long-wheelbase Grange platforms due to structural chassis routing, intermediate pipe lengths, and rear hanger location differences.

Features:

Precision-manufactured in Australia to deliver a premium flow upgrade, maximum structural longevity under intense heat, and a refined performance acoustic profile for the iconic VE sedan platform.

  • True Performance Cat-Back Layout: Comprehensive high-efficiency performance line engineered to bolt up securely downstream of the factory or premium aftermarket catalytic converter paths.
  • Factory Fixed Tip Integration: Specific tailpipe outlets engineered explicitly to slide directly into and align perfectly with the standard fixed chrome exhaust tip bezels built into the factory rear HSV bumper bar.
  • Sedan Specific Clearance: Custom-tailored plumbing path configured to route cleanly beneath standard sedan floor contours, rear subframes, and vehicle-specific bumper exit paths.
  • Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue.
  • 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 flow restriction.
  • V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of sports configurations without restricting gas velocity footprints.
  • Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel rear mufflers offer premium outer case reinforcement, completely preventing internal acoustic 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.

Important Fitment Notes:

  • Specifically engineered to fit HSV VE E-Series E3 Sedan variants powered by the 6.0L Gen IV LS2 V8 engine build date path (September 2010 to March 2013 builds).
  • Bumper Tip Requirement Configuration: This kit is specifically tailored for late VE E3 sedan builds that feature factory fixed rear chrome exhaust outlets integrated into the rear bumper fascia. The tailpipes feature an open-ended configuration designed to seat cleanly within those factory bezels without heat mapping or alignment issues.
  • Sedan Specific Routing Geometry: Due to variant-specific floor pans, rear subframe hanger arrangements, and bumper exit designs built for sedan structures, this layout features distinct intermediate lengths. It will not adapt correctly to Utility (Ute), Sportwagon, or long-wheelbase Grange platforms.
  • Direct bolt-on architecture interfaces seamlessly with original vehicle-specific rubber hanger brackets downstream of the catalytic converter assemblies. No custom fabrication, cutting layout mapping, or welding is required.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, verify strict exhaust component alignment, and ensure completely gas-tight structural seals.

Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.
Size: 300 Milliliter, Size: 300 Milliliter
Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can). Comes with dispensing attachment for easier pouring. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.

This stuff really works fast and improves mpg like you won’t believe
Size: 300 Milliliter
I’ve tried many other types of fuel injector cleaners but this brand is amazing. I ran my truck down to less than a quarter of a tank of gas and poured it into the tank. I then drove 30 miles to an appointment and spent an hour in the appointment on the way home I noticed my mpg had gone up significantly. My truck tells me how many miles per gallon. I’m getting as I drive. I had gotten a code and I replaced the mass air filter and found a slight crack in an air hose, which I replaced that help with my code a little bit, but cleaning the fuel injectors with this product made such a significant difference. I just simply had a hard time believing it, but it’s true. I’m done with all those other brands of fuel injector cleaners which never really seemed to help much if you really want an amazing experience give this product to try.
