Increase performance with the STILLEN Cat Back Exhaust for Infiniti G35 and Infiniti Q40. This exhaust features a Dual split rear exit. This STILLEN Infiniti G35 Exhaust has dual polished tips. The G35 Exhaust improves the sound and increases the performance of the vehicle.

STILLEN's Cat-Back Exhaust System helps drum up substantial horsepower and torque, giving your G37 the extra edge of performance. This Cat-Back Exhaust System is a true Cat-Back System, and is crafted of Mandrel-bent Stainless Steel for a long service life. At idle the STILLEN Exhaust is unobtrusive, and at higher speeds or under throttle, STILLEN's recognizable, performance sound is evident. This is a pleasing tone, authoritative and yet responsible. Not only does this exhaust system have a sharp, show ready look, but it also offers impressive horsepower and torque gains as well as a lifetime warranty and is easy to install.

STILLEN's Cat-Back Exhaust for the Infiniti G37 is built for power. Power that you can feel across the power band with a big gain on top. Mileage gains during highway travel can be expected as you cruise at steady speeds. The free flowing performance mufflers and tips are made out of polished stainless steel for long life. The Stillen fit and finish is second to none. The improved airflow created by the addition of the exhaust is verified by the significant dyno HP increase.

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

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.
