G8 GT Exhaust Sounds
Here is a montage of Exhaust sounds from my 2009 G8 GT. I have replaced the crossover muffler with a stainless steel X-Pipe, and replaced the factory axleback mufflers with some Flowmaster Super 44's. I am sorry about the lawnmower in the background of the startup/idle/rev and takeoff shots. Also, forgive me for not talking as a reference for the interior shots. I am new to the whole "videoing car sounds" thing.
