Borla Touring Cat-Back Exhaust System for 2014-2018 Chevrolet Silverado 1500/ GMC Sierra 1500/ 2019 Silverado 1500 LD ONLY/ Sierra 1500 LD ONLY 5.3L V8 Auto./ Manual Trans. Ext. Cab Std. Bed (78.7")/ Crew Cab Short Bed (69.3") 143.5" Wheelbase. (140544)

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.

The Best!!
As a proud owner of a BMW 328i Wagon, I'm always on the lookout for the best products to keep my car running smoothly and efficiently. After doing some research, I decided to give Liqui Moly Special Tec B FE SAE 5W-30 Motor Oil a try, and I'm extremely impressed with the results. This motor oil is specifically formulated with synthesis technology to meet the high-performance demands of modern engines, making it an excellent choice for my BMW. The 5W-30 viscosity rating ensures optimal lubrication and protection, even in extreme driving conditions and temperature fluctuations. I've noticed a significant improvement in engine performance since switching to this motor oil—the engine runs quieter, smoother, and more efficiently, with better fuel economy and reduced emissions. Plus, I appreciate the long-lasting protection it provides, helping to extend the life of my engine and reduce the need for frequent oil changes. The 5-liter size is convenient and cost-effective, providing plenty of oil for multiple oil changes. Overall, I highly recommend Liqui Moly Special Tec B FE SAE 5W-30 Motor Oil to BMW owners looking for a premium motor oil that delivers exceptional performance and protection.

Great oil and makes my engine run quieter
I noticed the engine running much quieter using this oil. The pour mouth is pretty unique for this brand, you can just open the interior cap, pull up the accordion neck and pour into the engine which provides better control over traditional wide mouth, thus less messy. This oil rarely goes on sale and is typically 1.5x to 2x more expensive than the more common US brands.
