Video Description:In this episode, we interviewed David Borla from Borla Exhaust! This is the man behind one of the most famed exhaust brands in the world. Here are some highlights from the video:
*At 2:43 he mentions how Borla products come with a million-mile warranty! Also, all their parts are made right here in the USA.
*At 3:28, he talks about how many other exhaust companies are actually muffler companies who simply bolt some pipe to a muffler to create an exhaust system, and how Borla distinguishes itself from them by engineering each system from tip to tail from scratch.

Description:
BORLA® Performance announces the release of a new quad-exit Cat-Back™ exhaust for the venerable 2008 – ‘09 Subaru WRX STi. This race-inspired system (PN140312) checks all the boxes on every Subaru enthusiasts’ hit list, taking this flagship to an even higher realm of performance.
For starters, BORLA® engineers upgraded the STi’s exhaust plumbing from 2.5 to 3” in diameter. The resulting increased airflow through the turbocharged powerplant provides horsepower gains of 7% - 10%. Hardcore enthusiasts who add Stage 1 or 2 chip upgrades will find this boost to the STi’s lung capacity vital to unlocking the ECU’s full potential.
Drivers negotiating terrain from rally course jumps to shopping mall speedbumps will appreciate how BORLA’s RD fabricators found room to tuck the system muffler higher than the OE exhaust, providing a 1.75” clearance gain. This additional room also enhances rear-section aerodynamics and improves appearance by reducing clutter.
Besides being higher, it’s lighter. Thanks to BORLA’s patented straight-through design that eliminates power-robbing baffles and chambers, the STi sheds approximately 8 lbs, making it a bit leaner meaner in a class where every bit counts.
True to form, the exhaust amplifies and enhances the STi’s distinctive rumbling gurgle with the rich bass of BORLA’s trademark sound of power. Combined with high-quality austenitic stainless steel construction and double-walled rolled-edge polished tips, drivers get the sound and looks they expect from the world’s most winning exhaust.
BORLA®, the original pioneers of high-quality stainless steel free-flow exhaust, utilizes patented award and race winning technology to deliver quality, sound, and performance gains. All with an easy bolt-on installation, and backed by a solid Million-Mile Warranty on all street systems.

Video Description:
Q: What does an ehaust system do? Why buy an exhaust system?
A: A performance exhaust system is used to increase horsepower for your car by allowing exhaust gases to pass through your exhaust system with less backpressure and less resistance. Larger-diameter piping is normally used, depending on the application, in order to gain more horsepower and torque levels throughout the power band. A performance exhaust system can be the most cost-effective modification you can do to get more horsepower out of your car, not to mention that it will give your car a deeper more aggressive sound. And depending on the brand, performance exhaust systems normally include gorgeous new mufflers that add a great appearance to your car.
Q: What exactly does "cat-back" mean when people say "cat-back exhaust"?
A: Many performance exhaust systems are also referred to as cat-back exhausts. Cat-back means that the exhaust piping starts from your catalytic converter and runs back all the way to the exhaust tip(s).
Q: How do you install an exhaust system?
A: Exhaust systems are installed using the supplied hardware, which includes gaskets and high grade bolts. This is truly a bolt-on procedure and most exhaust systems are an exact fit with no modifications needed. For this reason, getting a performance exhaust system is normally considered one of the easiest ways to gain noticeable horsepower for your car.
Q: Does a cat-back exhaust come with a catalytic converter?
A: No, "cat-back" actually means from the rear of the catalytic converter back, so it will include everything after the converter, but not the converter itself.
