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.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.

Love these.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I have them in black and white. I use them everyday in all shoes. These are very versatile and a great quality material. They take a looong time to wear and they stay in place. Very washable and good material. They are not too thick and they do not shrink. I do air dry mine. They do not hold smells even in the summer heat.

Perfect thickness and soft feel.
Size: 6-10, Color: Halo Gray/Assorted
Why did you pick this product vs others?: Love theses socks.  It's hard to find socks which won't get pulled down by athletic shoes.  These stay put.

Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip! I would compare these to Bombas but at a significantly better price point.
