Any one know if there are plans for a skunk2 or tanabe racing medalion or can i just buy one take to a muffler shop and have them weld 3 inch pipe all the way to the headers.

 

DOn't know about skunk stuff but do'nt do 3 inch. Bad Idea.

 

3" piping would cause a loss of low end torque unless you had a semi-powerful engine creating some serious backflow (i.e. super or turbocharging). I believe the one person and two or so companies who have turbocharged Lancers have kept the piping under 3". I'd suggest 2.25" or 2.5" for an NA engine.

 

2.5" is nice
