The 2016-18 Focus RS is a machine the demands attention and respect wherever it's driven. The Injen Technology cat-back exhaust system compliments the Focus RS with impressive power, gorgeous looks, and a distinct sound that is unmatched. , , Unlike our competition that uses stepped down tubing, the Injen Technology system is a full 3"cat-back unit that is mandrel bent using only the best 304 stainless steel available. Another unique feature of the Injen cat-back exhaust system for the RS is that is utilizes individual resonators instead of a single traverse style muffler. Not only does this provide a unique sound, but also help to free up power throughout the RPM range. Injen Technology also decided to bypass the factory exhaust valve and provides a custom exhaust valve bypass module (P/N 2002) with every Injen Focus RS exhaust system. This allow you to enjoy that rich, crisp sound of your RS whenever you want. , , The rear of the Injen Technology RS cat-back system is a work of art and employs multiple slip fittings to allow an infinite amount of adjustment for a precise fit right out of the box. Dual 4"black chrome exhaust tips complete the exhaust and provide a finished look. , , Quality Construction; This Injen Technology exhaust system is constructed from 3"mandrel-bent 304 stainless steel tubing for maximum flow and long service life. From there, every aspect of the system is hand TIG-welded by our experts in our Pomona, California headquarters. , ,

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
