Just wondering, are the pipes on all models going to be 3" pipes? Since there is an optional S/C I would think they have bigger pipes... Anyone have anything on this?

3" is insane. There would be no backpressure. I would have to guess 2.25", and later on an exhuast system that is 2.5" or so.

3" piping will cause power loss if its n/a. stock(factory) sc will need 2.75" piping. so 2-2.25" n/a stock would probably be my guess.

with a supercharger all you will need is 2.25 mandrel bent on the tC. only thing you will see 3" is on cars like supras.

i heard a recording of the tC stock exhaust from car and driver...sounds pretty throaty :D

No one has 3" stock, I was just making a extreme statement...

But obviously the n/a car would suffer if it's too big and the S/C would suffer if too smalll....

But I guess this isn't really a concern... Most people will change it to whatever they want after even if it means catless...
