Tundras are the biggest hunks of junk. Seen two of them in the fleet just break without even moving. Just sitting in a warehouse.

And I'm not exactly sure why you would think I was talking about a tundra when I said the Titan is built in America (or for your detailed needs, USA)

 

Hey dodge forum I'm new to this site and a newish proud owner of a early '98 dodge 2500 12 valve. It has 324k and has been passed down to me from my father. I have a lot of experiance maintains this truck but all of my customizing experiance is on gas motors.

Which brings me to my question. As I'm sure you guys know my truck is equipped with a catyletic converter and a muffler on a 4" exhaust. I was planning on moving up to a 6" exhaust and deleting the cat and moving to a high flow muffler. But since it is all mechanical what will the major decrease in back pressure do to the air fuel ratio?

 

Holy diameter batman

 

Titan, Tundra -- both begin with the letter "T" and are synonymous with the word turd.


FWIW - My Second Gen Ram was Vin 3, Hencho en Mexico, and based on what I gleaned from this forum over the years, the Messicans built better trucks than the union goons in Ohio.

 

Tundras are turds.

The 1st gen double cabs couldn't get out of their own way. lmao

 

Well I guess until you own one.. I thought the Titan was a much better truck than my 01 Ram and ran circles around the joke of the 02-08 rams (did the 07. That didn't last long..)

However thankfully Ram has stepped it up. I'm quite pleased with the 2012 Ram 2500 crew cab 4k miles on it and still hasn't gave me a hiccup

 

Probably nothing, after all, it's turbocharged. Letting it breathe a bit better may or may not give you a slight power boost. We have a couple diesel guys around here, start a thread about mods for your oil burner, and they will definitely have some suggestions.

 

I thought that was you....

 

Nope, I don't have ***** like that.

 

lets start with this: factory exhaust is 3" not 4" unless you have a common rail which would be 03-07.5.

next...6" exhaust all the way isn't going to fit under there, nor does anywhere I know of make a 6" exhaust kit... 4" is more than enough to flow as much as possible from the engine. 5" is really more for just sound or twins...

as for air fuel ratio...diesels are not like a gasoline at all. They are polar opposites when it comes to running lean and rich...diesels running lean run cold...diesels running rich run hot. but that said...they aren't super sensitive to it and it is easy to tell when they are lean or rich...just look for smoke out the tail pipe...lots of black smoke? running rich... no smoke? runing lean.

very forgiving rigs. want to make more power? add more fuel. have too much fuel making exhaust gasses get too hot? add more air via a bigger turbo... it is really that simple now of course there are supporting mods to make sure you don't break anything, but those are pretty basic and straight forward as well
