Designed to greatly improve exhaust flow and entirely made of 304 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 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.
NOTE: This downpipe doesn’t fit any USDM Subaru turbo.
The oem turbo heat shield will not fit on this downpipe.
**This part requires custom ecu tuning**
