Active Autowerke Bmw F22/F30/F32 228i/328i/428 Signature Exhaust

BMW PERFORMANCE PARTS: ACTIVE AUTOWERKE SIGNATURE EXHAUST for BMW F22/F30/F32 228I/328I/428 Product Features: This BMW F22/F30 exhaust delivers everything we know you would want in a performance exhaust: eye-catching style, a sophisticated yet aggressive tone, weight savings, and – most importantly – measurable horsepower performance gains! The muffler on this system turns your 328I exhaust tone into a sporty but mellow tone that is not only exhilarating but non obtrusive on your ears. The factory counterpart weighs 29 lbs. while the Active Autowerke Signature exhaust weighs only a mere 19 lbs. Weight savings are not the only attributes, this 328I performance exhaust has a modular design with its v-band clamps that makes fitment a snap. A revelation in BMW tuning. Finally, the real meat and potatoes will always be the horsepower numbers. On the in-house Active Autowerke Mustang dyno, our otherwise 100% stock 2013 328I test mule spun the rollers to the tune of an extra 9 RWHP, and 13 LB-FT of torque…from “just” a quality muffler upgrade. Turbos love to exhale, and we are very anxious to continue to unearth just how much extra power is hiding in the stock exhaust system. Larger diameter mandrel bent piping for maximum flow Durable, polished 100% 304 stainless steel Double-walled 80 mm signature stainless tips Adjustable tips with embossed Active Autowerke logo on the dual tip model Improved power & torque throughout entire RPM band Actual dyno measure results with gains of 10 + WHP over stock configuration Weighs 19 lbs. vs. the factory of 29 lbs. Fitment for coupe, convertible and sedans Complete illustrated instruction manual Two year limited warranty included NOTE: Exhaust system requires cutting of the factory pipe for installation. Dimensions and cutting measurements are included in the instructions. Some models have a round tubular pipe that makes the installation seamless. Other models have an oblong shape and will require welding instead of clamping. Fitment: BMW F22 228i BMW F30 328i BMW F32 428
