Yes, need to have it custom done welded.

I was looking at it though. I have a denali i think the transfer case gets in the way for me to run a true dual. what do you think?

Your denali is duel pipe to the muffler.
Run two mufflers and have a second muffler back pipe formed and your true duel.
This is how i did mine.
have a pipe installed as close to engine as you can to reduce low end torque loss.

can you install the long tube but keep the CATs? I live in california No cats is a no bueno.

Moving cats from the stock location is illegal as well. Meaning LTs are illegal in general.

I also couldn't get my Y pipe bolts off with an impact gun.
