• Fast Intentions releases a Porsche 991.1 Turbo cat back exhaust - $2195

      Maybe a little late to the party here but nice to have options. They bill this as a value in the Porsche aftermarket and that is true to a degree but $2195 for a cat-back system is not cheap. This is a completely bolt in, plug and play affair.


      • Direct OEM replacement; no cutting or welding required.
      • 2.75" mandrel bent T-304 stainless steel tubing.
      • Precision, hand fabricated x pipe.
      • 8" T-304 stainless steel perforated core resonators.
      • 3/16" thick, CNC laser cut T-304 stainless steel exhaust hangers.
      • 100% Tig welded.
      • Limited 3 year warranty on all welds, craftsmanship and resonators.
      • Application Specific: 2013-2016 991.1 Porsche Turbo & Turbo S.
      • All hardware included.
      • Built in the USA.


      • An increase in performance throughout the entire RPM band. The largest gains recorded were: 31 horsepower at 5,000 RPM / 33 foot pounds of torque at 4,800 RPM.
      • Custom x pipe technology efficiently balances exhaust pulses within both engines banks, creating a smooth and refined exhaust note.
      • 100% slip fit design; allowing you to retain OEM catalytic converters and exhaust tips.
      • Weight 13.8 lbs. (10 lbs. lighter than the OEM exhaust.)
      • Retains OEM heat shields with no modification.
      • Reduction in EGT (Exhaust Gas Temperature.)

      They do share a dyno which is what we like to see and the gains on a Mustang from just a cat-back are quite nice:

      The mid-range improvement in particular is solid.

      We do not see many users running Fast Intentions Porsche products but it certainly is nice to have options to compare.

        Lol WTF. That end of the video is totally deceiving. They did 171mph with Xona upgraded turbos at 28 psi ~ 700AWHP.

        That car will never do 188mph with those turbos.

        Shows how much more impressive my 166mph on stock turbos at 22psi was. JB4 FTW.
