What is HPHouseAE?

HPHouse Automotive Engineering is a performance-focused automotive parts brand specializing in high-quality exhaust systems and selected performance components.
Precision-engineered performance systems, built from the ground up for real-world dominance.

🚗 What products do you sell?

We currently focus on:

  • Exhaust systems (valved & non-valved)
  • Downpipes (catted & decat/off-road)
  • Custom exhaust configurations
  • Selected performance parts (model dependent)

Our catalogue is expanding continuously.

If you don’t see your vehicle listed, contact us, we may still be able to help.

🧩 How do I know if a product fits my car?

Every product is vehicle-specific.

If you’re unsure about fitment, simply contact us with:

  • Car make & model
  • Year
  • Engine variant
  • Any existing modifications

We’ll guide you to the correct setup.

🛠 Are your products bolt-on?

Most of our systems are direct bolt-on replacements using factory mounting points.

Some setups (especially race or custom configurations) may require professional installation or minor fabrication. We’ll always let you know in advance.

🔊 What’s the difference between valved and non-valved exhausts?

Valved systems allow you to switch between quiet and loud modes at the press of a button.

Non-valved systems are always in their aggressive sound profile.

If you want daily comfort + performance sound, go valved.
If you want maximum raw sound, go non-valved.

🏁 What do “Unleased”, “Control”, and similar terms mean?

  • Unleased – Maximum flow, aggressive sound (usually no mufflers)
  • Control – Valved exhaust with quiet + loud modes, depending on model can be either applied with supplied remote control or as per OEM controls        
  • Street Pipes – Include high-flow catalytic converters, options of 100 Cell, 200 Cell, or 300 Cell
  • Race Pipes – No catalytic converters (track use only)

If you’re unsure which suits your build, just ask.
