Hands down the best craftsmanship,
"Hands down the best craftsmanship, looks and Sound of any similar product out there!"
Amazing!
"Purchased this for my 991. 1 Targa and as soon as I put my foot down, the valves open and the engine screams get out of my way, a massive smile immediately spreads from ear to ear. Workmanship is amazing, sounds amazing and I LOVE it. Only issue ove notes is the install was a little tricky and I still can’t get the back pipes evenly level. The package did arrive in rather rough shape so I’m wondering if it’s not slightly bent somewhere?"
Q&A
- Does this fit a base 911 with 3.4 liter engine without PSE?
- Yes, this exhaust system will fit your base 991.1 Carrera with the 3.4L (2012–2016 models) even without Porsche Sport Exhaust (PSE). It's a direct bolt-on cat-back designed for the entire 991.1 Carrera lineup (base, S, GTS), and non-PSE cars have factory exhaust valves that the system integrates with via an optional controller for manual operation. No modifications needed.
