CTS Turbo Ford Raptor EcoBoost 3.5L High-Flow Cat Downpipes

CTS Turbo Ford Raptor EcoBoost 3.5L High Flow-CATS are made to maximize exhaust flow for highest power gains. Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from 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 3.5L Twin Turbo, our High Flow-CATS will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "note. While up-shifting you will enjoy a confident "punch!" as you bang through all 10 gears. The sound will be even louder if you already have an aftermarket exhaust system. We highly recommend getting our turbine adapters at the same time for improved exhaust flow and power. Product Details:

• Designed and tested on a real car in the real world
• Cast T304 stainless steel, TIG welded back-purged construction
• 200 Cell High Flow-CATS - not compliant with emissions

Using the optional CEL eliminator greatly reduces the possibility of CEL coming on for cat efficiency code. This is not guaranteed to be 100% effective. Stage 2 downpipe-specific software tuning is required to avoid a check engine light.
