CTS Turbo is proud to announce our proprietary high-flow downpipe for 2018+ Audi 8V RS3/8S TTRS with 2.5L TFSI EVO (EA855) engine.
This stainless steel high-flow downpipe that allows the user to remove the restrictive factory "main catalytic converters". This downpipe is a part of our modular exhaust system and it is compatible with factory or CTS Turbo mid-pipes.
We used CAD simulation to streamline the flow of exhaust gasses and ensure that it splits evenly into two outlets. Many hours of R&D were spent to ensure perfect fit, smooth exhaust flow and excellent sound.
Features:
Large 3.5" downpipe outlet splitting into dual 2.5" pipes
Durable 304 food-grade stainless steel
Laser cut flanges and precision machined v-band
Factory-like placement of O2 sensors
Designed using the latest 3D scanning technology
Exhaust flow simulated with CAD software to ensure optimal flow routing
Perfect fit with factory or aftermarket mid-pipes
Aggressive sound - really makes that 2.5T scream
No drone under normal driving conditions
Optional driveshaft removal tool (based on factory Audi tool, required to remove and install driveshaft)
Fitment:
2018+ Audi RS3 2.5T EVO (EA855)
2018+ Audi TTRS 2.5T EVO (EA855)

DESCRIPTION
CTS Turbo B9 S4/S5 3.0T (EA839) high flow cat is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts – unleash your B9 S4/S5 3.0T potential!
Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from cast T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance.
In addition to unleashing the power and performance of your 3.0T, the CTS B9 S4/S5 3.0T EA839 high flow cat will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “braappp!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.
