There is a "whirring" sound when in 6th gear. Using the sport shift, I dropped it down to 5th and the sound quit. I noticed it happens when cruising on a level roadway. There is no whir when going downhill or uphill.
Anyone else notice a "whirring" sound when in 6th gear?
Does anyone know if installing headers will void my warranty? If so I may just have a better exhaust installed since its way too quiet for me! Any suggestions between Borla, Magnaflow, Flowmaster???? Thanks
