Title says it all. Found exhaust leak caused by broken bolt in manifold. Have to remove manifold to fix. Might as well install headers. Can't find any headers for 05 ram with hemi. All start with 06 and up, or 03 and lower. What are you 05 guys using?

 

They have them out there the year must be mismarked. Pacesetters, are you looking for long tube or short tube?

and for the broken bolt soak it down with some good break lose fluid any kind works good. If its sticking out see if you cant get a bite on it to twist it out.

 

Broken bolt is more of an excuse for new headers. No real problem getting it out. I figure no real difference between 03 and 05 but dont want to order and find out the hard way. Long or short doesnt matter. Short is less money and work, similar to oe replacement. Thanks

 

Yeah both have good Hp gains.

Longtube stays steady through hp gains
Short some say you lose a little bit of hp but the Hp spike is greater than long tube.


Im pretty sure there is no difference

 

I helped a buddy install the exact same model Pacesetter LTs that are on my '04 on his '05 about four years ago, so unless they are discontinued, they are out there...

 

Hammer, do you think there is enough of a gain with the long tubes versus the shorties to justify the extra work? You have to move or delete the cats with the LT's right? And extend the o2 sensor wires? Any other big differences?

 

I asked a few guys who did the shorties on Rams who told me not to bother, the small gains didn't justify the cost or effort. But I talked to a couple with LTs (some who had tried shorties first) who swore by the long tubes - plus I was able to obtain some dyno files from Marty when he was at KRC Performance to confirm gains with LTs.
Personally, I couldn't feel much if anything really down low but in the mid and upper rpms it's very distinctive.

My cats are back about 14" or so, or at least that's about how much I had to splice in to my '02 sensor wires...

 

You mean you couldnt tell a difference bn the two down low or not much from stock to the lt's at low rpms?

 

Shorties are supposed to provide more low end torque then HP and LTs are supposed to be good for mid to high end HP but not torque

 

Headers of any length provide gains over a stock manifold, both torque and HP. The thing you need to realize is that the engine doesn't need to work as hard to expel gases with headers since headers scavenge these gases instead of letting them sit and mixing in the manifold, thus forcing the engine to have to "push" these gases out into the exhaust system. Generally, the longer the tubes, the more vacuum is created to help scavenge these gases.

The "issue" here is since the engine doesn't have to "work" as hard at these very low end RPMs, there is a perceptible feeling of low end torque loss. The engine is actually running more efficiently. It's commonly said that better breathing equates to torque loss with HP gains, but in reality a dyno will show torque is actually increased - BUT the peak torque is moved up higher in the RPM band.

Since shorties do not scavenge as efficiently as long tubes (although certainly better than manifolds) the torque curve is not moved up into the RPM band as far as it is with long tubes. Of course there are other mods you can do with LT headers to increase torque down low (cam with a grind cut for more low end, less top end for example) which will give you the best of both worlds.

In my case, with the cats still in-tact, I don't feel any low end torque loss - but I can't say I see any gains either. However, there is no doubt the gains from say 2200 rpm and up are VERY feel-able after I went to long tube headers...
