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)

Tux it up!
Color: Black, Size: Large
My wife thinks this makes me look like a red carpet celebrity. It’s an amazing fit and very well made. The stitching is up there with designers. You can’t rent a tux for this cheap! Awesome value for the look. Its a very thick but light fabric. Its git a little stretch to it as well. I love that it has the vest as well. Its clean lines and hugs the body!

I absolutely love this set.
Color: Dark Green, Size: Small, Color: Dark Green, Size: Small
This tuxedo is kind of awesome for a couple of reasons. One is the price, it's a really good value for the three pieces you get. Two is the design. It's really well cut and the pants are not too large and the color I ordered (the deeper green, which I think they call emerald green) is absolutely beautiful. I like that it's a little bit different from traditional tuxedos while still looking understated and classy. It's quite versatile in terms of when you can wear it. It doesn't scream tuxedo, although it satisfies the requirements of one, so you could simply wear it as a nice suit for special occasions. Construction seems meticulous, with outstanding stitching and pockets and nicely done details. Check out the photo for a close up of the detailing. I ordered this for a young man going to the prom and It is perfect for that occasion. Definitely recommended.

Check the size chart but looks great, slim fit and fairly good value for what you get.
Color: Black, Size: X-Small, Color: Black, Size: X-Small
I got this MY'S 3 Piece Men's Suit for an upcoming wedding I need to attend and it fits fairly well. I am 5' - 10" with a waist around 31" and I went with the XS. I normally wear a medium so be sure to check the size chart since you can't just order your typical size. The suit is a slim fit so also keep that in mind as well. The material is good for the value and everything looks great. There are plenty of pockets which adds some texture to the look but they are semi-sewn shut which I just found out is more common than you'd think. You have to carefully cut and pull out the thread to fully open the pocket or you can leave it for a cleaner look. Overall, I am happy with this suit and think it is a decent value for the material and quality that you receive.
