Description

The Iroz Motorsport STM Mid Pipes are a direct replacement for the restrictive, secondary exhaust pipes on select Audi RS3 and TTRS models. Crafted from fully stainless steel, these mid pipes are TIG-welded with back purging for enhanced durability and performance. Each pipe weighs 3.4lbs, resulting in a total weight saving of 6.7lbs compared to the factory pipes, which weigh 13.5lbs. The package includes all necessary mounting hardware, featuring (2) STM 2.5" Exhaust Pipes, (2) 3-Bolt Remflex Gaskets, (6) M8 x 35 Bolts, and (6) M8 Nuts for a leak-free installation. They are proudly made in the USA and come with a Lifetime Warranty on STM Parts against manufacturing defects for the original purchaser. Vehicle fitment includes the 2017-2025 Audi RS3 (8V/8Y) and the 2018-2022 Audi TTRS (8S), specifically models equipped with DAZA and DNWA engines. Please note that these mid pipes are intended for track and race-only use, and buyers should check their local laws before purchase.
