Does NOT fit (N26 SULEV) 2.0T engine. This BORLA® Cat-Back™ system is designed specifically for the (N20) 2.0T engine. The system features our classic S-type sound with no drone inside the vehicle. The 2.75" diameter into dual 2.25" tail pipes system exits thru dual (one on each tail pipe) 3.14" round polished T-304 stainless steel tips. BORLA® Cat-Back™ & Axle-Back exhaust systems feature patented straight-through and multi-core technology 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 austenitic 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.
