I've heard different views of the straight pipe and how big it should be.

Which would be better... 2" straight pipe or 3"? It'll start from the manifold back. I've never heard a 3" going on a N/A besides the TII. I am not too sure if that's "good" with an N/A because of back pressure? I could be wrong?.

More.. information needed please

 

2 1/2 is optimum for a relatively stock NA, Of course it does bump you out of stock class in auto-x Christi

 

I'm not caring about my class in Auto-xing. I will never beat the 944 dude in my class.....I just want a change in pace with her. I've been wanting a straight pipe for a while now.. and i've got my chance.

I was explained by the guy.. that the 2" piping is a lot better than the 3" for a few reasons...

Isn't the manifold 2" piping (Well, around the hole? If that makes much sense) anyway, and getting a 3" piping is kinda useless? More so for show than performance? By the way you look at it anyway.

 

Yeah I would say 2 1/2, but then I would say buy a header instead.
