WTF. Why do the V-6 engines have only one exhaust port per side

Looking at the Taco engine today i see one exhaust port per side . What gives

 

From the manifold?

 

It might only have 1 port per side, but it's got 2 CATs!!

 

From the head...

 

Newer head designs have the manifold, in a way, built into the head. See the link below for an example.

This matters, why?

 

Exhaust manifold is cast into the head. Chrysler did this with the Pentastar 3.6L in 2011. It allows the cat to be placed closer to the head and heated up to operating temps faster.

 

The 4 banger has 4.

 

Outside the box. I guess i still live in the dark ages. Well it works anyway. Thanks for answering my question.

 

This should have been a sign not to go there. Newer Chrysler engineering is to make something that last less than 100K miles.

 

on the bright side. when working on heads the worst part (to me) was all the studs used to attach the header snapping and having to remove them. less studs less problems?

 

Class action

 

Meh

Lots of 2 GRs out there with this design. Not a peep that it's been a problem.

 

Its secretly a Harley Davidson V-Twin engine. This explains the lack of power, poor shifting, oil leaks, poor gas mileage, and poser band wagon fans.

 

None of that with this guy....;-)

 

Is that why my Taco’s exhaust goes:

“potato-potato-potato-potato-potato”

 

Do you want to stay away from V6s just because Chrysler V6s are unreliable? Maybe we should all go to mid-engined cars because front-engined Chryslers are unreliable?

Having the exhaust manifold cast into the head eliminates a few potential long-term reliability issues like cracked exhaust manifolds or leaking manifold gaskets.

 

Seems like it puts the manifold into the cooling equation of the block rather than air cooled outside the block. Less piping probably saves room and concentrates more manufacturing into a single casting. I guess we'll see if the increased complexity of the head leads to different kinds of failures, possibly more prone to overheat?

 

cant help but wonder if those will be an issue and limitation when it comes to forced induction... not that i was going to put 7k into my engine but ill be happy to learn from others that do
