The 2.75″ diameter BORLA Cat-Back system for the Civic Type R is unique in the industry with triple tips and an adjustable sound level. By changing the block off plates behind the center tip you can adjust the SPL (Sound Pressure Level) to your taste. System features BORLA’s Polyphonic Harmonizer Technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the BORLA mufflers. The mufflers then enhance this sound to the character and volume appropriate to deliver the aggressive ATAK sound with no drone inside the vehicle. System features 3 black coated tips, 1) 4.5″ round (center) and 2) 4″ round (outer). Systems with polished T-304 stainless steel tips, and carbon fiber tips are also available

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 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 numerical control (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) exhaust brand.
