NEUSPEED's all-stainless steel catalyst-back exhaust system rivals the best that any Audi/VW tuner has to offer! No other exhaust can even come close or compare to our high standards of fit, quality, and design. Our exhausts use quality T304 stainless metric-sized tubing for maximum flow. Two low restriction mufflers at the rear are carefully designed to have minimal drone inside the cabin, reduced weight and meet State noise restriction standards. Mandrel bends, precision fit flanges, mounting hangers, gasket(s) and hardware are standard on every NEUSPEED exhaust system.Just like the electronic engine sound amplifier, no gimmick exhaust flappers used on our exhaust, just pure deep sound.NEUSPEED Exhaust Rated #1 by Installers as having the best fit, quality, and performance!Notes:Fits: 2015-up Audi S3 8VFeatures:80mm Pipe (3.15")T304 Stainless Steel Mandrel Bent PipeStainless Steel Polished MufflersPrecision Fit Flanges (no cheap multiple piece slip fit pipes)Stainless Steel Quad 100mm Polished Slash-Cut TipsDesigned and Engineered Camarillo, CaliforniaLimited 2-year warranty to the original purchaserActual part shown in the photoWeight:Stock: 50 Lbs.NEUPSEED: 38 Lbs.NOTE: To eliminate exhaust flapper fault code and/or CEL, VCDS is required to uncheck Exhaust Flaps Installed.
