Borla S-Type Cat-Back Exhaust System for 2006-2010 Jeep Grand Cherokee SRT-8 6.1L V8 Automatic Transmission All Wheel Drive 4 Door. (140245)

Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.

The Borla "Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase 'Cat Back' and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.

Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don't have a factory service-point require "cutting" the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation. Many of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators. Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode.

Features:

  • Horsepower and Torque Increased by 7 – 10%
  • Increased exhaust flow for better performance
  • Better fuel economy at cruising speeds
  • The most aggressive sound of any Borla system

Excellent all-poly athletic socks for general lifting and HIIT.
Size: Medium, Color: Black/White/Grey
***These are NOT “low” -cut socks as the description in the title states. These are actually “quarter”-cut socks as clearly visible in the picture of the sock itself. “Low” -cut socks are shorter than this height but still visible with a shoe. Also, on the actual UA package of these socks, it clearly states these are QUARTER cut socks. My review: Gave these UA Performance Tech socks (UAPT) 5 stars since they’re very good but in all reality not the best socks I’ve ever had for lifting and HIIT workouts. That title goes to Nike Dri-Fit MAX socks (DFM)….but these socks are really good. Like Nike’s DFM’s, these UAPT socks come in sizes, halleluah (M, L, and XL). The idea that most athletic sock are sized 6-12 and should therefore fit everyone perfectly is absolutely ridiculous. Your shoes come in whole and half sizes…so socks should at the very least be sized like these UAPT’s and Nike DFM’s…in S/M/L or in this case, M/L/XL. I wear a men’s size 8 shoe and the M (medium) size in these socks was a perfect fit; true to size. Also, UAPT socks are ALL polyester with Spandex which is ideal and 100% that which you want for athletic socks: wicking with stretch. Cotton socks are the absolute worst thing you could wear to the gym since they’re sponges for sweat and therefore get wet and heavy, cause blisters, tend to stink, stick to skin, etc… IF you prefer cotton socks for athletics, then you don’t understand how performance fabrics work in athletics and training. You do NOT want cotton in your athletic apparel. You want your fabrics that wick sweat away; NOT soak up sweat and hold onto it. Also, the flexibility and stretch of the foot and ankle parts of the sock were both just right. Snug but not too tight. Wicking is perfect, too. Already worn during two 3 1/2 hour workouts and my feet stayed as dry as a desert. When looking for UA athletic socks on Amazon, I surprisingly continued to find UA “athletic” socks made with mostly cotton which completely surprised me because a serious athletic company should produce an abundance of performance-level socks… i.e. all-poly socks. Thank goodness I finally came across these UA all-poly Performance Techs. The only drawback to these UAPT’s…and it’s a minor drawback…is that unlike Nike DFM’s, these do not come in L & R (left and rights) to specifically match the individual foot shape. Nike DFM socks come in L and R which sets them apart from all other athletic socks…and yet I don’t like supporting a massive monopolistic athletic apparel company like Nike, but they’re the only one that makes THE best athletic sock. Nonetheless, these UAPT’s are perfect workout/HIIT/lifting socks for the bundle value price of six pair and three colors. If you’re looking to match your new UA or Rock shoes with the appropriate UA athletic sock, then here you go. I chose the black/white/gray mix bundle since I have new pairs of a black and a white version of the same UA-Rock shoe. These UAPT socks are medium thickness so they didn’t take up an exorbitant amount of room in my shoes but they’re thick enough to prevent blisters and provide cushion. Overall they’re very comfortable, hold a good stretch, hold their shape, and seem to be durable but only time will tell. And since we’re on the black and white sock subject, I couldn’t resist: I read a shoe review about someone angered that his new UA/Rock black shoes (obviously bought for casual wear in lieu of gym use) staining his white cotton socks. First of all, never ever wear white socks (much less cotton white socks) with black athletic shoes! The possibility of staining is always there and the appearance just doesn’t work. However, you can get away with black socks with white shoes in some cases…but never white socks with black shoes. Why? Who knows? It’s just one of those unwritten rules of the gym. And no, I didn’t make the rules…so don’t blame the messenger. LOL!

Great cushion and solid fit. Some days my feet are tired from the compression fit, but they do support my feet well.
