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 austenitic stainless steel, superior to T-400 series knockoffs, to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer-controlled 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.
This stainless steel rear exhaust section replaces the heavy (and restrictive) stock exhaust system on the S55 engine. Shed excess weight and restriction, and get a better sound! You will love the rich, deep sound this tuned system gives your M3 or M4. There's a throaty and purposeful growl at low RPM and at cruise that highlights the six-cylinder engine under the hood.
