PART DESIGN

• In-house designed and engineered using FARO ARM laser scanning technology for precise fitment 

• 3.0" T304 Stainless Steel Mandrel Bent, Brushed Tubing with 1.25mm wall thickness

• Dual 2.5" Tailpipe Sections with Tig-Welded Merge Pipe and Laser-Cut ECS Logo Plate 

• Lighter weight than the OEM catback exhaust:

  • OEM catback (without tips) - 42 lbs 

  • ECS Valved catback (without tips) - 33 lbs (-9 lbs weight savings) 

  • ECS Non-Valved catback (without tips) - 31 lbs (-11 lbs weight savings) 

• T304 Stainless Steel 12mm barbed round stock exhaust hangers Tig-Welded in OE locations for precise fitment. A rubber exhaust hanger bushing is included for the rear subframe location for additional support.

• Strategically placed slip joints provide the most adjustability to obtain perfect fitment

• VALVED MUFFLER:

  • Tested multiple muffler designs to achieve the most desirable exhaust notes with the largest delta between valve closed and valve open driving experiences 

  • Valve Closed Routing - 3-chamber perforated reduction tubes with stainless steel wool packing material provides a sporty driving experience without causing excessive resonance, volume and performance loss

  • Valve Open Routing - Straight-through 3.0" perforated tube with stainless steel wool packing material provides the most unobstructed flow path for race-inspired driving experience to maximize volume 

  • Vacuum-actuated exhaust valve provides outstanding reliability in the harshest conditions. Unlike electronic servo motors that are prone to failure, our exhaust valves have been tested in thousands of applications and have proven to be reliable. 

• NON-VALVED MUFFLER:

  • Straight Through "Turbo Style" Muffler

  • In-House designed to provide a sporty driving experience like no other

  • Perforated core with stainless steel wool packing for sound absorption  

• Designed to maximize ground clearance while still being compatible with aftermarket components such as our ECS Tuning Rear Subframe Brace.

PERFORMANCE FEATURES

• VALVED: Dyno tested on our in-ground Mustang "AWD 500 SE" Dyno with our ECS Tuning Shop MK7 GTI we showed maximum gains of +9 WHP and +8 FT/Lbs of torque while equipped with our ECS Kohlefaser Luft-Technik Intake, APR Stage 1 93 Octane Software and the OEM downpipe, with the exhaust valve open. 

• NON-VALVED: Dyno tested on our in-ground Mustang "AWD 500 SE" Dyno with our ECS Tuning Shop MK7 GTI we showed maximum gains of +9 WHP and +15 FT/Lbs of torque while equipped with our ECS Kohlefaser Luft-Technik Intake, APR Stage 1 93 Octane Software and the OEM downpipe.

PRODUCT DEVELOPMENT

• Our ECS Tuning Catback Exhaust System was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing. 

INSTALLATION AND SUPPORT

• Looking for installation tips? Look no further, we put together a full installation tutorial from start to finish including how to remove your OEM parts! See our Installation PDF under the INSTALLATION Tab for more information. 

• ​​**VALVED SYSTEM NOTE: A manifold vacuum source is required to activate the interactive exhaust valve --- This is NOT included but available under ES#2986667 (intake manifold port) or ES#2984817 (throttle body)****

   

NOTE:

• Aftermarket ECU software is recommended to maximize performance gains as advertised.
