Frequently Asked Questions

What performance gains can I expect from a Holden Colorado exhaust upgrade?
Typically, you'll see improvements of 5-15% in power and torque, plus better throttle response and fuel efficiency after installing Outback exhaust system.. Turbo-back systems deliver the most significant gains by reducing exhaust backpressure.

Are Outback Exhausts systems louder than stock?
Outback exhaust systems produce a deeper, more refined tone than factory exhausts without excessive cabin noise. You'll enjoy an enhanced sound during acceleration while maintaining comfort on long highway drives.

Do I need a tune after installing a new exhaust on my Holden 4x4?
For DPF-back systems, a tune is typically not required. However, turbo-back systems may benefit from ECU tuning to maximize performance gains.

How long does installation take for a Holden exhaust system?
Most bolt-on systems can be installed in 2-4 hours by a competent mechanic or experienced DIYer. Professional installation is recommended for best results.

What's the difference between aluminized and stainless steel exhausts?
Aluminized steel offers excellent value and corrosion resistance for most conditions. Stainless steel provides superior longevity and is ideal for coastal areas or extreme environments with maximum corrosion protection.
