Hi guys, ive recently purchased a 2009 FG XR6 in dash green, and I am wondering whether a catback exhaust system is worth it, and will I have any issues from the police as a p plater. I was thinking of purchasing this exhaust (https://www.deaperformance.com.au/p/Store-Wide-Sale-Excluding-XForce/Falcon-FG-XR6-Sedan-2.5-Inch-Catback-Exhaust-Syste/ST219HD-246D-TIPS) , and I am wondering whether it is legal for p platers as it is illegal to have performance enhancing mods, and I don't know whether the police consider it is a performance modification, due to it not actually being an engine mod and wont do anything but make the car sound a bit better. if that's not a good exhaust could you recommend any others.
Thanks.
