If the factory exhaust on your car sounds like an appliance, a catback system is the fix. Our catback exhaust systems replace everything from the catalytic converter back, delivering a noticeable improvement in sound and, on the right platform, modest gains in exhaust flow and mid-to-top end performance. We stock systems for popular performance cars in Australia including the Subaru WRX, Toyota GR86, BMW M3 and M4, and more — with fitment specific to Australian-delivered vehicles. Options range from a subtle, refined note all the way to full-aggressive track sound, so you can dial in exactly the tone you're after. All systems ship fast across Australia via express freight, and professional installation is available at our Sydney workshop for a clean, rattle-free fit. Browse the full range below.
