I have excessive drone from my exhaust and just wondering if many people had the same problem and know how to stop this huge drone! Recently bought a exhaust for my FG XR6 turbo 4" Dump into 4" cat then twin 2.5" which I bought of Ebay (http://www.ebay.com.au/itm/FORD-FALCON-FG-XR6-TURBO-4-0LT-SEDAN-COMPLETE-TWIN-2-5-HURRICANE-EXHAUST-/170976421085?pt=AU_Car_Parts_Accessories&fits=Plat_Gen%3AFG&hash=item27cefd24dd&_uhb=1) Drone will basically start from 1500RPM all the way up to 3000-3500RPM. While crusing at 60km/h & 100km/h its quiet as and really nice as well as a nice rumble at idle. The only other thing I have done is purchase a Herrod performance air box (http://www.herrodmotorsport.com.au/HerrodPerformanceProducts/EngineComponents/FGPerformanceAirBoxKit/tabid/293/Default.aspx) If any body could help me solve this problem it would be great!
