PART DESIGN

• In-house designed and engineered using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling for precision fitment 

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

• The beautifully crafted final assembly is artfully Tig-welded and back purged for superior durability and the finest appearance

• A stainless steel, wool packed resonator cuts down on unwanted drone

• Features a straight-through 3.0" flow path leading up to the muffler assembly which then splits into quad 2.5" tailpipes for the least amount of restriction and turbulence 

• Valved Muffler Design:

  • In-house engineered to achieve the most desirable exhaust notes with the largest delta between valve "closed" and valve "open" driving conditions 

  • Perforated tubing combined with stainless wool packing material helps to absorb unwanted volume and minimize drone throughout a specific RPM range

  • Our system reuses the factory electronic servo-valves in order to retain OEM valve control, in addition to keeping installation simple.

• ECS Valved Catback Weight: 55 lbs with exhaust tips and downpipe adapter 

• T304 Stainless Steel 12mm barbed exhaust hangers, featuring 360° hanger stoppers, are Tig-Welded in OE locations for precise location

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

• Designed to maximize ground clearance while still being compatible with aftermarket components, such as larger rear sway bars.
