I had to look it up myself so I knew I was sending you the right direction.....
What you are looking for is the gibbson super truck side exit exhaust. As for headers; if you got the dough for them, pacesetter makes long tube that will add GOBS of torque. But to use them you will need to have new Y pipes fabbed up. Otherwise, a set of stainless ebay shorties like what I got fit the bill nicely, for under $150.00
