Pacemaker 2.5" Full Performance Cat-Back Exhaust System for Holden & HSV V8 Sedans (VT, VX, VY & VZ) - PP5361-01

Unlock significant horsepower gains and unleash a deep, uncompromised muscle roar from your 5.7L LS1 or 6.0L Gen IV engine with the Pacemaker Sport Systems heavy-duty twin 2.5" performance cat-back exhaust solution. Specifically engineered for the classic rear floor pan geometry of standard-wheelbase Holden Commodore and HSV sedan configurations across the entire VT, VX, VY, and VZ generations, this high-velocity system bolts up directly to existing catalytic converter locations. As Australia’s premium exhaust innovator, Pacemaker integrates elite acoustic engineering with patented V-Tex technology and signature double-skinned mufflers to offer an aggressive, commanding exterior rumble while completely counteracting intrusive cabin boom or highway drone. Note: Fits Holden and HSV Sedan models (1999–2006) equipped with 5.7L or 6.0L V8 engines.

Features:

Precision-manufactured in Australia to deliver a premium flow efficiency upgrade, heavy-duty scavenging, and an unmatched depth of sound for the V8 sedan platform.

  • True Cat-Back Setup: Complete twin performance mid-section and tail exit assembly designed to secure cleanly behind your factory or aftermarket converters.
  • Premium Materials: Constructed completely from durable Exhaust Grade 409 Stainless Steel for superior longevity under high thermal stress.
  • Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structures guarantee a completely uniform internal diameter to prevent restrictive backpressure.
  • V-Tex Technology: Advanced internal anti-drone configuration filters out harsh cabin boom frequencies while retaining deep exterior exhaust notes.
  • Signature Mufflers: Double-skinned 409 Stainless Steel mufflers offer superior casing strength, zero internal packing blowout, and refined tonal control.
  • Direct Bolt-On Layout: A 100% full bolt-up design matching original mounting points under the sedan chassis—no custom fabrication or modification required.

As good as high end
Size: 38W x 30L, Color: Navy
These pants fit and feel like much more expensive pants. They’re true to size and very comfortable! Prefer them to jeans any day of the week and are as dressy as I need!

Cheap and worth it.
Size: 42W x 28L, Color: Black
Cheap and looks nice, tbh. I orders a 42wx28l and it was a nice fit. I order 28L so the seam usually can sit above my ankle or shoe but It was a bit longer compared to my other various pants at 28L, it felt more like a 30L. I’ve noticed the waist seems to fit a bit larger than I’m used to but overall a nice fit and material. One thing worth mentioning is the stitching at the bottom seems a bit loose.

High Quality Cotton, Well Cut
Size: 36W x 32L, Color: Black
I was pretty impressed with the high quality of these pants. Remove the Amazon label and you wouldn't think twice if it had a Gap, Banana Repblic or Levi's instead. They are well cut and well stitched. I ordered black and the color looks great too. Fits to size.

Great fit
Size: 36W x 32L, Color: Dark Khaki
My boys love these pants. College son prefers them when he is golfing. They fit well and are comfortable. He usually wears southern tide brand which are extremely pricey. So happy to have found these. Already ordered in multiple colors. They are nice and thin for Florida weather
