The 5.0L V8 Windsor motor in the AU Falcon was imported from the US, and made up to 220kw (depending on model and specification), however this figure was restricted by the factory exhaust system, which ran as small as a single 2 1/4? pipe! This meant the engine was restricted at high RPMs, and lacked low down torque and responsiveness. By fitting an upgraded Manta exhaust system, significant benefits can be experienced, including a throaty V8 exhaust note (with no drone), increased power and torque, and improved fuel economy. The 2.5? single exhaust is ideal as a budget replacement for your stock exhaust, while still giving some performance gains. The 3? single exhaust system gives good increases in power and torque, while for the ultimate in sound and performance, the dual 2.5? exhaust is the way to go! It’s the only dual 2.5? exhaust available in Australia for the 5.0L V8 AU Falcon, and therefore a very unique and desirable upgrade to your vehicle. The full exhaust system with extractors will give the most noticeable increases in power and torque, while the cat back system is ideal if you are just looking for better sound, or a replacement for your stock exhaust system.
