Borla S-Type Cat-Back Exhaust System for 2017-2020 Honda Civic Si 1.5L 4 Cyl. Turbo Manual Transmission Front Wheel Drive 2 Door Coupe. (140777CB)

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
  • Custom designed for each application
  • Patented straight-through, multi-core muffler design reduces backpressure while absorbing sound waves
  • Mandrel-bent stainless steel tubes with diameters optimized for reduced restriction while maintaining exhaust gas speed
  • Made from the finest austenitic stainless steel for long-lasting durability
  • All welded construction
  • Includes everything required for installation, including detailed instructions
  • Backed by the exclusive Borla Million-Mile warranty
  • Proudly made in the USA more

BORLA Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere.

Each system is built from premium T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit.

Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning)

Love this pillow!
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
Love this pillow. I bought 2. No weird smell and the cover is half cooling and half bamboo. It is also removable so that it can be washed. The inner pillow insert has a thin permanent cover on it to keep the shredded memory foam enclosed, this is standard compared to other memory foam pillows I've bought in the past. I got them on a used like new discount, and they were still vaccum sealed and truly like new. I couldn't be happier with these pillows, I am so glad I got 2.

So Comfy
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
I'm obsessed with this pillow. Been looking for a good body pillow but could only find the kinds that have that polyester filled from the stores and usually they flatten out easily. But found this out and its filled with memory foam and the casing has a nice cotton feel and the other side is a cooling side which I love. Its so comfortable and can easy be reshaped back from the memory foam. It's worth it.

Wish it was more “cooling”
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
The pillow is somewhat comfortable, I don’t find it “cooling” it does hold its shape and it gets really fluffy. I am a hot sleeper I was hoping it would help with the cooling but I find it no different than any of the other body pillow’s I have bought

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.
