well i have the stacks how id like them in my truck, but i wanna connect them up as soon as the 4" is in, but when i connect them and i join the stacks up from where the original exhaust runs under the truck and then i pop it up into the box and connect it, but if it's off to the passenger side to much will the passenger side stack show more smoke then the drivers side? and should i route the exhaust so it pops up more in the middle of the box /connector pipe for the stacks?

 

It doesn't matter where you connect your exhaust to the crossover pipe, the smoke will equalize for the most part before it exits the two stacks. At worst, only at start up will the smoke leave one stack micro-seconds prior to leaving the other.

 

When mine starts up, the passenger side puffs a little more than the driver side. But when I lay into it, id just don't matter, it all comes out and rolls to the ground
