Fabspeed's Valvetronic Exhaust System is the ultimate cat-back setup for the ultimate street-drivable GT4 dual use street/track car. New anti-resonance technology makes for an even more enjoyable experience.                            

SOUND:

We're proud to offer a premium exhaust solution for the Porsche Cayman GT4. Our Valvetronic Exhaust offers two distinct tones depending on valve position: mild and wild. It was important to retain civility around town with valves closed, mission accomplished. You'll be able to enter your neighborhood after a midnight joyride without having to explain yourself at the next HOA meeting. Open the valves, and you'll be treated to a glorious roar befitting of the GT4. Burbles and backfires erupt in abundance, and downshifts summon a bark that will make all eyes and ears around focus on you. We're not exaggerating. This system will put an ear-to-ear smile on the most miserly of faces.

POWER:

When combined with Fabspeed's Race Headers, our Valvetronic Exhaust System allows you to push 375 whp out of your GT4! Even with Sport Headers coming in at 371 whp, the gains in power are as impressive as the sound. The Fabspeed exhaust suite completely eliminates the torque dip in the 3500 RPM range and offers power gains all the way through redline. The increase in low end power will make a great difference in street drivability with the long gearing of the GT4.

Best phone holder I have ever purchased!
Color: Dark Black, Size: 1 Pack
Hands down the best phone holder I have ever purchased. The ones that stick to the windshield always end up coming loose. This attached to your vent and is super sturdy. Very easy to install and uninstall without making a mess on your window.

Well worth it. Great product.

For the inexpensive price it’s worth its weight in gold. I admittedly probably didn’t work on it as long or as hard as I should have, but I still had great results. *** One warning: when it says to “tape up and cover your paint around it” do it! I figured I would just be careful but no I was wrong. It will REALLY damage your paint, so make sure you don’t get any on it. YES- This is the sanding discs too! They have chemicals on them, they are not regular discs. If you do get on paint, clean immediately! My only regret with this project and my fault, not theirs. My headlights went from dingy yellow, to much brighter and definitely more clear. Love the results. Very happy with the purchase.

Great for the price
Size: 1 Kit, Size: 1 Kit
Worked great at clearing my headlights and at a great price, I had used a different headlight kit maybe 5-6 months before and it did not perform as good as this kit did, maybe it was a user error with the previous kit but this one cleared it easily and was very easy to do and had a nice clear shine.
