Hey guys, I am now planning on purchasing a downpipe but I have one question? I was looking at different types of downpipes, and some of them have a 2.5" inlet with a 3.0" outlet, and other ones have a 3.0" inlet instead of 2.5". Which one do I need? I have a Big 16G turbo, if that helps.

 

Anyone know?

 

i think either on will work fine. As long as it has the right size flange that will fit on the turbo
