  • Damn that sounds pretty good. Might have to look into one for my 4.3

  • Does this truck have the 4.3L v6?

  • hey mine are comming out in the same area as yours and mine are duals on my 2000 gmc sierra did this improve your mpg?

  • whoa identicle to my truck!

  • @snakesonaplane2 Mine is also a GMC but a 95 with the 305 and it's a longbed but same dark green color, I want it midnight blue though.

  • I have the same exit, mine has 3.5"x24" angle cut tips with a Magnaflow muffler, and a Thunderbolt highflow cat. I'm looking at going with chrome Daytona wheels and Indy 500 tires, make it look more like a Nascar truck.
