• Smoke stacks! by Sierra94 on 15 Feb, 2013 13:18
• Someone on the forum told me to put stacks on my truck, so when I found a box full of leftover stainless bends etc at work I started building a set last night.
  
  But I need some opinions. Should I keep or remove them? I havent made the hole throught the bed yet. And the stacks need a good polish to get shiny.
  
  
  
  
  
  
  
  
  
  And some work in progress pics:

• Pretty neat idea!
  
  How about putting these on top?

• Looks great, I am not partial to symmetry so I would prefer to have a single. Not necessarily a 7" like the one I put on my dad’s truck for his build. The straight out of the bed with no turns is what I would run if it were mine. If I had a diesel cabby it would have one (with no top).

• Are there any performance gains? One stack  pipe vs two vs straight 2.25 inch pipe all the way back
  
  If not, I'd think it would basically aesthetics?

• I like 2 more than one. And I already have 3 inch straight from turbo and back. The stacks are 3 to 3.5 inch pipe. So it wont make any gains.

• You can reduce drone if  one leg is a half wave longer.

  huh,, learn something new every day.
  
  I just personally do not like seeing single stacks on dual exhaust engines or dual stacks on single exhaust engines.
  
  IE. Two stacks on a Cummins, or single stack on Duramax or PowerStroke.

• Yes! Stacks. Must have.  Perhaps right behind the drivers door.

• I sense sarcasm....

• Sarcasm? No! It's cool.

• The drone won't be that bad since the exit is just above the cab. Any lower and you will tear them out.

• I made some changes today before grinding/sanding the welds down. I narrowed the connecting pipe between the stacks 2 inches on each side to make the stacks follow the outer line of the cab instead of making it look so "square" as they did before. And they are gonna get one inch higher from the roof when finally mounted in their brackets.

• Plastic Zip ties?   My exhaust gets too hot for that to stay secured.  Tell me you have thin cables planned for the final look and feel?  Simple bike cable with an overlapping smash aluminum oval might be the ticket.
