The Borla for the E46 323/328 is a full exhaust - bolting to the stock exhaust header/cat and continuing all the way to the rear. No cutting or welding! Most other exhaust systems for this car are only the rear muffler but this is the entire system in 100% stainless steel. This exhaust will really wake up the 323i/328i with a deeper tone and much improved flow over the stock system. We see gains of over 10hp with this system alone. And the entire front-back system weighs just 31lbs - a substantial weight savings that will also make the car accelerate, corner, and brake better! But the best feature of this exhaust has to be the sound - throaty and with a deep rumble that makes the M52TU engine sound very aggressive.

Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty. Turner Motorsport has been the leading Borla dealer for BMW exhausts since we sold our first system in 1996, including using Borla Exhausts on all of every Turner BMW racecar.
