Made from high quality T304 stainless steel TIG welded pipework, this APR vavled exhaust system, coming with all the necessary assembly hardware, fits without any modifications from the downpipe of the Audi S4 B9 and Audi S5 F5. Designed to bring an aggressive tone to the 3.0 TFSI engine and a sportier looking to the car thanks to its quad 90mm polished tailpipes, this catback has a primary diameter of 3.5" / 90mm, reduced to 2.5" / 63mm offering a gain of about 10hp on a stock engine.
