If you're unsure which downpipe you need for your car, please take a picture and I can verify if it fit ours or not.  Comes with All hardware and gaskets necessary for the install.  Professional installation might be required.  This is a 3" downpipe coming out from your stock 3 bolt turbo flange, then it could be customizable to your 3" exhaust or 2.5" exhaust.  Comes with two o2 bungs with plugs, if you do decide to use them or use one for your EGT sensor.  Might not pass smog in some States.  The most restrictive part of any exhaust system is the catalytic converter.  The stock catalytic converter is meant to filter the flow of the exhaust gases to reduce the amount of harmful gases into the atmosphere.  That is a potential performance restrain.  Downpipes eliminate the stock catalytic converters and reduce exhaust back pressure by maximizing exhaust flow.  This downpipe allows the turbo to spool up a lot faster and also build boost quicker.  The result brings out the vehicle's performance potential by giving it a high free flow exhaust system.If you have any questions, feel free to contact us anytime.
