Product Details

The perfect way to let your engine breathe in a modern turbocharged engine is to upgrade the restrictive factory downpipe and front-most resonator with a smoother, higher flowing unit. This is a great way to increase performance and add a sophisticated growl to the exhaust note. Ideal performance is achieved through expelling exhaust gasses at maximum velocity through a larger diameter, freer flowing downpipe due to smoother bend radius and a larger internal diameter.  

When paired with our standards of quality and design requirements here at ECS Tuning, we can humbly provide to you the greatest downpipe upgrade available. Through multiple design iterations and stringent product testing, we have engineered our High Flow Downpipe to not only let your engine breathe, but to provide trouble-free installation with a true and honest, perfect fitment guarantee.

Designed and engineered in house, our High Flow Downpipe utilizes only premium materials and world-class manufacturing techniques to deliver unmatched quality and reliability. Mounting up to the OEM catalytic converter, our mating flange is made from thick CNC-Cut T304 stainless steel and is then precision ground for an optimum gasket sealing surface. A new downpipe gasket and clamps are included for a trouble free install. 

All exhaust tubing is 3.0" T304 Stainless Steel CNC Mandrel Bent with .065" wall thickness for reduced cabin noise and increased life span of the product. Each weld joint is hand TIG welded for precision and strength and eye-catching beauty.  A stainless steel flex section provides proper range of motion and heat expansion. The downpipe mounting point features a barbed hanger connection for a direct fit to the OEM downpipe mounting bushings to prevent disconnection. 

To complete our downpipe, we've included a 2.5"-3.0" expanded reducer with 2.5" Accu-Seal exhaust clamp that reduces to the OEM exhaust size. Please note that our downpipe ends at the factory clamping location and is 3.0" OD at this connection point. If using an aftermarket catback system some modifications or additional components may be needed. 

Our ECS Tuning High Flow Downpipe System offers impressive real world results. Each system is hand crafted from premium materials and comes with a 5 year limited warranty with a perfect fitment guarantee! This means less frustration and less downtime during installation over many others.
