Borla Stainless Steel Headers

BORLA – STAINLESS STEEL HEADERS

Uncompromised quality and precision manufacturing is what you get in all Borla Stainless Steel Headers. Borla’s Stainless Steel Headers are designed to make your vehicle look and sound better and you will feel the extra horsepower and torque every time you hit the gas pedal. For maximum exhaust flow, pair a Borla Stainless Steel Exhaust System with your Borla Stainless Steel Header and indulge in your engine’s additional horsepower and torque. This writer purchased a Borla exhaust for his truck way back in the 1990s and now that truck with the same Borla exhaust has been driven over 500,000 miles with no trouble at all. The Borla exhaust still looks great and sounds fantastic after many years and many miles of use. A Borla Header does cost a little more than most of the competitor’s headers but for that extra investment you get Borla’s excellent fit and finish, the highest quality T-304 stainless steel and peace-of-mind knowing that you purchased a quality header that will outlive most other brands. Alex Borla’s well-engineered exhausts have exceeded the expectations of car, truck and off-road buffs as well as the professional motorsports community since 1978. Mr. Borla started his company with one single purpose, to engineer the best exhaust systems on the market. Borla’s state-of-the-art manufacturing facility in Tennessee uses high tech computer based CNC manufacturing tooling and equipment and employs America’s finest metal workers. Borla goes the extra distance to provide you with the highest quality, best fitting and nicest sounding exhaust for your driving enjoyment.

NOTE: With the exception of five headers made for Jeep Wranglers, which are a 50 state street legal design, the rest of Borla’s headers are purposely built for off-road or racing use if your vehicle came equipped with a catalytic converter from the factory when new.

"I purchased a set of Borla Headers 10 years ago for my 2.5RS they were very easy to install even in my driveway. The Sound is Outstanding as well as the entire Power Band if you have a NA Subaru and want more power this product is for you no dissapointments." posted by: Li'l Red Wagon on October 18, 2011

"I recently put a pair on my 2003 Subaru Baja, the install takes 5 minutes... once you painstakingly undo the bolts on the old factory header. It sounds unreal almost like a harley at idle. It really improves the mid range torque without sacrificing any on the low end" posted by: Bill on July 14, 2008
