Why did they put manifolds on these trucks? I can’t imagine they couldn’t fit the same headers that come on the cars with the hellcat.

Hmmm... interesting question, is it possible to get a picture of these manifolds?

Aren't they basically shorty headers?

Next time I get a chance I will take pics. I can only get the passenger side from the engine bay.

from what I can gather, manifolds are more like a plenum and actual headers are 4 pipes that merge together further away from the engine

I guess I get cafe standards lol. I’m just shocked the truck is already a lower horse power, but then to put on manifolds? it’s like….”I know we already cut back on your HP from all the other hellcat platforms, but one more screw you is we will give you less flowing exhaust manifolds.

No, no - I get that. I know the difference. I just thought they put the same manifolds on, on my Scat Pack they are basically shorty headers.
On the TRX it must be for clearance or power curves.
This is on my car

Here are som pics I took from a video of the manifold
Another thing a lot of people don't know or think about is when you improve the exhaust flow, you will loose actual boost psi. Which would allow you to run a smaller blower pulley or a bigger crank pulley. Sounds odd I know, but it's all about efficiency, efficiency goes up, more air can get into and out of the cylinders.

From those pictures headers look like they might be a major undertaking.

Looks like it would all be tight that is for sure
Might be tight but the gains will be worth it! Look at these high flowing beauties from SW with x pipe!!
