The FG XR8 inherited the BOSS 290 5.4L V8 from the BF FPV GT, producing 290kw. The performance of this engine was nevertheless hindered by the restrictive stock exhaust system, and substantial gains can be realised by fitting a Manta Performance exhaust upgrade. The Manta exhaust helps unleash greater peak power and torque, while also improving low-down responsiveness. It also brings out a deep, rumbling V8 note, enhancing your driving experience, making the car sound like it really should! There are a number of options, depending on your budget and requirements. The 2.5″ dual system sounds fantastic, with a deep throaty tone. However for the ultimate in performance and sound, the 3″ dual system can’t be beaten, being the only true dual 3″ all the way through available for the V8 Falcon. For maximum longevity, our stainless steel systems are warranted for 10 years, and generally last the life of the vehicle, while our aluminised steel systems carry a 2 year warranty, and represent great value for money.
