Description

Fabspeed Porsche 718 GT4 / GTS / Spyder Valvetronic X-Pipe Exhaust System (2020+)The Fabspeed Valvetronic X Pipe Exhaust System for the 718 4. 0L cars wakes up the sleepy Porsche PSE exhaust and gives them a truly exotic sports car sound all while retaining the functionality of PSE (Porsche Sport Exhaust). Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that

The Fabspeed Valvetronic X-Pipe Exhaust System for the 718 4.0L cars wakes up the sleepy Porsche PSE exhaust and gives them a truly exotic sports car sound all while retaining the functionality of PSE (Porsche Sport Exhaust). Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we settled on using our CAD flow engineered investment cast X-Pipe and 2.5" 63.5 mm tubing for the most power and exotic sports car sound. The CAD flow modeled X-pipe is an exclusive Fabspeed part that gives a smooth high pitched exotic sound and flows much better than a X-Pipe handmade from U bends cut and welded together. The exhaust valves we use are made by Helical Limited in the United Kingdom. These ISO 9001 certified valves are the same ones Ferrari, McLaren and Porsche use on their GT cars. The flanges are thick 304 stainless steel that we CAD designed to perfectly match the OEM flanges and reuse the factory metal gaskets. 

SOUND:

With PSE off our Valvetronic exhaust gives a nice subtle increase in volume. With PSE on and the valves open it turns the 4.0L's exhaust note into a truly exotic sound with a significant increase in volume. This system will turn heads as you rip by. 

POWER:

This system makes power throughout the entire RPM band. On our DynoJet we saw +15 whp and 11 ft/lbs of tq at 7,600 RPM and a healthy does of torque down low at 2,400 RPM gaining +28 ft/lbs of tq and +13 whp. This is low end torque you'll really feel around town and horsepower that continues all the way up to redline.

FEATURES:

  • Fits all 718 Cayman/Boxster GT4 / GTS / Spyder Cars 2020+ (Please see the note below for how to identify if your car has early or late model exhaust brackets)
  • Significant Dyno gains across the RPM band. +28 ft/lbs tq @ 2400RPM, +10 ft/lbs tq @ 4800RPM, and +15 whp @ 7600RPM
  • Weight savings of 4lbs 1.8KG vs the factory exhaust
  • Helical Limited U.K. Silicon Carbide exhaust valves
  • CAD designed X-Pipe made using investment casting for maximum possible flow and spectacular sports car sound
  • Constructed from high-quality 14-16ga CNC mandrel-bent T304L stainless steel for optimum flow and maximum durability
  • Emissions legal in all 50 states

Sweet but good.
Size: 1.45 Pound (Pack of 1)
Make sure to buy flavorless fibers as well and blend together with this one at least 50/50 if not 25/75 since it's very flavorful and very sweet with not so healthy sweeteners.

Tell R&D to find a new flavor house, this tastes awful
Size: 1.45 Pound (Pack of 1)
This “berry” flavor tastes astoundingly terrible. It is a wonder to me that this could have passed any product development team. It is like the worst kind of cough medicine mixed with bitter off notes, and it is a very strong flavor, so it is very in your face. The orange original is not great tasting but not bad, you would assume they would only release a new flavor if it was better. They ought to call a flavor house and reformulate this, the technology exists to make this taste good, but wow, this is really unpleasant.

Good flavor
Size: 1.45 Pound (Pack of 1)
Good flavor. I quit drinking Metamucil in the past because I didn't like the orange. I was reluctant to try a different flavor but after reading many positive comments about this one I decided to try it. I was not disappointed. Thank you to all who left positive comments about the Berry flavor.

Great Product, Works as Advertised
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
This product works exactly as described. It makes BM's smoother and gentler. I personally use the unflavored, no sweeteners added version, and honestly, it does not taste very good, but I feel that the results are worth it, and I do not like adding extra sweeteners or flavorings to my diet. I have used this product for many years and have found that about 1 1/2 to 2 tbsps in 12 ounces of water works the best for me. You will need to experiment a bit to find the ratio that works best for you. I recommend that you start on the low side and gradually increase the amount of Metamucil as needed.
