PART DESIGN

CATBACK:

• 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 

• T304 Stainless Steel 12mm barbed round stock exhaust hangers Tig-Welded in OE locations for precise fitment (Note: RR exhaust hanger will need rotated 180 degrees)

• 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:

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

  • Perforated core with stainless steel wool packing for sound absorption  

  • Straight Through "Turbo Style" Muffler

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