Designed to greatly improve exhaust flow and entirely made of 304L stainless steel, this downpipe is efficient and resistant. 
 
 The bellmouth opening and 3.5 inch top portion will reduce turbulence and allow for smoother flow from the turbo to the downpipe.  
 
 It is built with a 1/2 inch thick laser cut rear flange to minimize heat distortion and provide a true 3 inch fitment all the way through.  
 
 We have also welded an additional oxygen sensor bung for any tuning needs or wideband sensor install. 
 
 Includes an adaptor to fit with an OEM donut gasket.  
 
 Available catless or with a 300 cell high flow catalytic converter. 
 
**This part requires custom ecu tuning**
