Frequently Asked Questions

Will a Holden Trailblazer exhaust system improve performance?
Yes. Outback exhaust systems reduce back pressure and improve exhaust flow, resulting in noticeable gains in power, torque, and fuel efficiency. Most customers report improved throttle response and better towing capability.

What's the difference between turbo-back, cat-back, and DPF-back systems?
A turbo-back system replaces everything from the turbo outlet back, offering maximum performance gains. Cat-back systems replace components from the catalytic converter back, balancing performance and cost. DPF-back systems replace from the diesel particulate filter back.
