    Excellent desicion

    Just what I was looking for, better sound, lots of bubbles, no turbo lag anymore. I combined with fabspeed air filters, feel more power, enjoying it a lot so far.

    I highly recommend this product to all 958.2 Cayenne GTS owners! 1. It is super easy to install. The fitment is perfect! 2. It enhances the stock exhaust note with nice bubbles! No Resonance! 3 .It enhances throttle response especially in mid rev range, turbos spool faster! 4..Bang for the buck!

    That's my car in the video.

    The car is 1000% more fun to drive now. The video doesn't show what happens when you run close to the redline at 6,000+ RPM. It's a howling beast. I have an 8-cylinder Panamera S with full Fabspeed exhaust and an 8-cylinder Cayenne S with full Fabspeed exhaust package. Both are louder but the 6-cylinder, twin-turbo 2016 Cayenne has a scowling, popping, race car like sound that is amazing. If you have a Porsche, put a Fabspeed exhaust on it asap!
