The Borla axle-back exhaust for the 2012-2015 Honda Civic 1.8L uses 2.25 inch tubing and delivers the classic S-Type sound with no drone inside the vehicle. It features a 4.25 inch x 3.5 inch oval polished T-304 stainless steel tip in a single right rear exit for a sharp appearance. The all-welded, straight-through muffler and Borla's patented multi-core design increase exhaust velocity to free up power while producing the distinctive Borla Sound of Power. This is a street axle-back system that installs behind the factory catalytic converter and is 50-state emissions legal. It is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate fit. Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty.

FAQ
What vehicles does the Borla 11828 fit?
It fits the 2012 through 2015 Honda Civic with the 1.8L 4-cylinder engine in front-wheel drive, including LX, EX, EX-L, HF, DX, GX, SE, and natural gas models.
How does the S-Type sound level compare?
S-Type is Borla's aggressive sound level, sitting between the mild Touring and the loudest ATAK. On the Civic it gives a stronger tone than stock with no in-cabin drone.
Is the Borla 11828 50-state emissions legal?
Yes. It is a street axle-back system that installs behind the factory catalytic converter and does not remove emissions equipment, so Borla lists it as 50-state emissions legal.
What are the tip and tubing dimensions?
It uses 2.25 inch tubing and exits through a single 4.25 inch x 3.5 inch oval polished T-304 stainless steel tip at the right rear.
What is it made of and is it warrantied?
It is handmade in the USA from T-304 austenitic stainless steel with all-welded construction and is covered by the Borla Million-Mile Warranty.
