lots of people use single stacks. they look/sound great! have a sharper tone than dual stacks.

hey tengo,the reason i used "flex pipe"is thebox of your truck moves separatly from your cab,if your stacks are mounted to your box and then welded to your exhaust and you do a little 4x4ing and get the box to twist a bit you may break somthing.i easily could have welded straight to the exhaust with pipe as i was already in line with it but i figured{and my muffler shop freind who helped}thought a piece of flex was the way to go,i know that the 3inch is small but i only have a small hole in my box and i dont have the huge wye fitting.thare are many ways to install your stacks,pick the one that suits you best.
