# APR 17-21 Porsche Macan MQB Turbo Muffler Delete - Black APR's 2-Piece Design Explained: As is true with all machined parts, it's impossible to make all parts the same. In the case of the turbo muffler housing, the distance between the bottom and top of the muffler's housing will vary from turbo to turbo. The acceptable measurement range is known as a tolerance. The nominal distance between the top and bottom of the turbo muffler's mounting points is roughly 51 mm. The tolerance on this part can be as loose as +/- .5mm or more. This means some muffler housings will be up to 51.5mm tall, or as low as 49.5mm tall. Since the distance between the top and bottom of the muffler chamber will be different on every turbo, a 1-piece turbo muffler delete will always be either too tall or too short. On systems that are too tall, the delete will touch the bottom but will not touch the top mounting point, creating an imperfect seal and potential for a boost leak. If the part is too short, the system will seal at the top, but will leave a small gap at the bottom, thus negating the purpose of the part as illustrated in the diagram below. APR's 2-piece design solves this issue with an adjustable height design. While a 2-piece design is more difficult and expensive to manufacture, it's the only way to ensure an accurate fit and perfect seal. APR provides a Viton seal that's placed at the bottom of the muffler housing. The muffler cover is then installed forming a seal with the factory gasket. Then, the center tube is inserted and screwed into place to the desired depth, compressing against the Viton seal to ensure a leak proof seal in every scenario. Finally Tension from the seal prevents the tube from coming loose, and the included Loctite provides extra security from movement. With the turbo muffler deleted, the APR design provides a smooth, turbulence free, and leak proof path for airflow existing the turbo! - 2 piece design with gasket eliminates leaks / factory tolerance issues - Removes the factory turbo muffler - CNC machined billet aluminum - Better power delivery - Enhanced turbo sound - Anodized black - Faster spool This Part Fits: Year Make Model Submodel 2015-2016 Audi A3 Premium 2015-2016 Audi A3 Premium Plus 2015-2016 Audi A3 Prestige 2015-2020 Audi A3 Quattro Premium 2015-2020 Audi A3 Quattro Premium Plus 2015-2019 Audi A3 Quattro Prestige 2009-2014 Audi A4 Base 2009 Audi A4 Cabriolet 2015-2019 Audi A4 Premium 2015-2019 Audi A4 Premium Plus 2015,2017-2019 Audi A4 Prestige 2019 Audi A4 Titanium 2019-2022 Audi A4 allroad Premium 2019-2022 Audi A4 allroad Premium Plus 2019-2022 Audi A4 allroad Prestige 2009-2012 Audi A4 Quattro Avant 2009-2014 Audi A4 Quattro Base 2009 Audi A4 Quattro Cabriolet 2015-2022 Audi A4 Quattro Premium 2015-2022 Audi A4 Quattro Premium Plus 2015,2017-2022 Audi A4 Quattro Prestige 2019-2020 Audi A4 Quattro Ultra sport 2010-2014 Audi A5 Cabriolet 2010-2014 Audi A5 Quattro Base 2010-2014 Audi A5 Quattro Cabriolet 2015-2016,2018-2022 Audi A5 Quattro Premium 2015-2016,2018-2022 Audi A5 Quattro Premium Plus 2015,2018-2022 Audi A5 Quattro Prestige 2017 Audi A5 Quattro Sport 2019-2022 Audi A5 Sportback Premium 2019-2022 Audi A5 Sportback Premium Plus 2019-2022 Audi A5 Sportback Prestige 2012-2018 Audi A6 Premium 2012-2018 Audi A6 Premium Plus 2018 Audi A6 Sport 2013-2015,2017-2022 Audi A6 Quattro Premium 2013-2022 Audi A6 Quattro Premium Plus 2018 Audi A6 Quattro Sport 2021-2022 Audi A7 Sportback Premium Plus 2021-2022 Audi A7 Sportback Prestige 2013-2016 Audi allroad Premium 2013-2016 Audi allroad Premium Plus 2013-2015 Audi allroad Prestige 2026 Audi Q3 Base 2019-2025 Audi Q3 Premium 2019-2025 Audi Q3 Premium Plus 2019 Audi Q3 Prestige 2020-2023 Audi Q3 S-Line Premium 2020-2023 Audi Q3 S-Line Premium Plus 2020 Audi Q3 S-Line Prestige 2013-2016 Audi Q5 Hybrid Prestige 2011-2021 Audi Q5 Premium 2011-2021 Audi Q5 Premium Plus 2018-2021 Audi Q5 Prestige 2020 Audi Q5 Titanium Premium 2020 Audi Q5 Titanium Premium Plus 2020 Audi Q5 Titanium Prestige 2020-2022 Audi Q5 PHEV Premium 2020-2022 Audi Q5 PHEV Premium Plus 2020-2022 Audi Q5 PHEV Prestige 2021-2022 Audi Q5 Sportback Premium 2021-2022 Audi Q5 Sportback Premium Plus 2021-2022 Audi Q5 Sportback Prestige 2017-2022 Audi Q7 Premium 2017-2022 Audi Q7 Premium Plus 2022 Audi Q7 Prestige 2020 Audi S3 Premium 2015-2020 Audi S3 Premium Plus 2015-2019 Audi S3 Prestige 2016-2023 Audi TT Quattro Base 2016-2023 Audi TTS Quattro Base 2017-2021 Porsche Macan Base 2019-2021 Volkswagen Arteon SE 2019 Volkswagen Arteon SE R-Line 2019-2020 Volkswagen Arteon SEL 2019 Volkswagen Arteon SEL Premium 2019-2021 Volkswagen Arteon SEL Premium R-Line 2019-2021 Volkswagen Arteon SEL R-Line 2018-2021 Volkswagen Atlas S 2018-2023 Volkswagen Atlas SE 2018,2020-2023 Volkswagen Atlas SEL 2020-2021 Volkswagen Atlas SEL Premium 2020-2021 Volkswagen Atlas Cross Sport S 2020-2023 Volkswagen Atlas Cross Sport SE 2020-2021,2023 Volkswagen Atlas Cross Sport SEL 2021 Volkswagen Atlas Cross Sport SEL Premium 2022 Volkswagen Atlas Cross Sport SEL R-Line 2023 Volkswagen Atlas Cross Sport SEL R-Line Black 2016 Volkswagen Golf Base 2015 Volkswagen Golf Launch Edition 2015-2018 Volkswagen Golf S 2015-2016,2018 Volkswagen Golf SE 2015-2016 Volkswagen Golf SEL 2017 Volkswagen Golf Wolfsburg Edition 2017-2019 Volkswagen Golf Alltrack S 2017-2019 Volkswagen Golf Alltrack SE 2017-2019 Volkswagen Golf Alltrack SEL 2015-2019 Volkswagen Golf R Base 2016 Volkswagen Golf SportWagen Limited Edition 2015-2019 Volkswagen Golf SportWagen S 2015-2018 Volkswagen Golf SportWagen SE 2015-2018 Volkswagen Golf SportWagen SEL 2015-2021 Volkswagen GTI Autobahn 2019 Volkswagen GTI Rabbit Edition 2015-2021 Volkswagen GTI S 2015-2021 Volkswagen GTI SE 2017 Volkswagen GTI Sport 2019 Volkswagen Jetta GLI 35th Anniversary Edition 2019-2023 Volkswagen Jetta GLI Autobahn 2019-2021 Volkswagen Jetta GLI S ## Details - **Price:** 187.26 CAD - **Vendor:** APR - **Type:** Hoses ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 187.26 CAD | In stock | ## Images - Photo - Primary - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/apr-17-21-porsche-macan-mqb-turbo-muffler-delete-black) > Updated: 2026-07-04
