QUICK REV: 911 GT3 with a gmgracing exhaust center section. A Porsche Exchange customer was kind enough to allow us to record a few revs after he stopped by for a car wash the other day. This system takes the already great OEM sound and brings it up a notch. This is a nice system if you don't want anything CRAZY loud, but you'd like a more aggressive sound. You also pick up a few HP, drop a couple pounds and retain the factory sport exhaust option. Keep in mind that the GT3 is rev limited to 4,000 RPM while not in gear, so this clip doesn't accurately showcase the high-pitched wail it makes while under load at high RPMs. Turn the volume up and enjoy! #Porsche #PorscheGT3 #911GT3 #GT3 #GMG #GMGracing
