Hey guys, not much left of the winter, so almost time to start fixing the chevy up again! (its so freaking cold now)

First of all, how are these called: PIC.
And you guys now where i can order those but a bit longer?

Second of all, im going to change the exhaust a little on my truck. Are 2" pipes a good size for my 217ci in-line 6?
