i plan on running dual pipes out the back, probly 2.5 inch pipes. id like to have true dual pipes ran. besides buying the headers, is there a website or company that makes pre-made kits per specific truck that you can buy without having a machine shop custom make the entire system?

 

wow! you started a debate here on DF, hahahaha just kidding. Some people swear there's no problem running TRUE duals, and some say you have to run some sort of x or h pipe for the backpressure or you'll damage the motor. I'm not sure if they make a kit for it, but you can surely have an exhaust shop fab that up for you. Can't wait to see what people's opinions are.

I don't know of any kits on the market, I would really love a new set of headers, That in it self opens up a bigger debate, some are convinced they help, some will say save your money.

I'm the pro side of a true dual set up, removeing the y pipe and running two muflers just made sense for a work truck towing on the high way.

Down side is finding good quality muflers and a shop that knows muflers..

On my truck, I needed a new 02 sensor, the old one in the y pipe could not be used and the rear tail pipes were fabbed up over the rear diff, The shop did not have a mandrel bender, and at the time, I thought this was ok due to having some back pressure in the ex.

Go true dual, or leave your truck stock, loss of back pressure was never a issue with my 6sp manual, I don't see any gains with my mods until I tow, or hit the highway, Than the ex pays for it self.

 

im 98% sure they dont make a true dual bolt on kit, gonna have to be custom, and heres some good readin on exhaust may change your mind or confirm ur consensus...http://autolounge.net/tech/exhaust.html

 

True duals aren't worth the expense IMO, but if you want it the best setup on a Ram is 2.25" with an X or H pipe, and you'll probably need a shop to do it, which will still be cheaper than a kit.

 

dont true duals actually add to performance whereas running a Y out the back is only for looks and pointless as far as adding HP and watnot towards the engine?

 

He's saying to run duals, if I'm right, but to add an x or h pipe to distribute the gases evenly. They do add hp and perfomance, but depending on the size only at certain rpm's. you would probably gain the same as running a cat back with single in, dual out muffler. You're really only talking about a HP or two, not that much if I've read correctly.

 

Here go's my x or H pipe rant....

Thiers no room under a 4x4 hemi to even consider this, yes, a H or X pipe is benifical, how ever,, all ex pipes have to be equal in length, on the a stock hemi, the left ex pipe of the manifold has a bend to fit in front of transfer case, the right is shorter and meets the left ex pipe in a Y.

The disagreement on going to true dual's is that the Y design is the cheaper factery version of a X or Y pipe and by adding a less resstrictive muffler from the cat back will give you a cheaper version of a dual ex.

The flue tank on a 4wd hemi takes up a lot of space, but thiers room to run to mufflers on the side ( not on the flat )

When you have to ex pipes flowing into one in a Y design, the stock ex sytem is all ready unbalanced when the pipes of the manifold are not equal, by removing the Y and going with two stright pipes into two individaul muflers, the engine to move's air out quicker.

The stock mufler is verry restrictive, its more for a sound deading than performance, but a louder mufler will not increase performance.

From my expireances with my conversion, do not ever run one mufler with 2 inlets and 2 out lets ie DYNOMAX ULTRA FLOW... Stay with two muflers.

 

so ur sayin i can run an X or H pipe off my existing cat? and run a Y pipe off that for dual exhaust? i dont completely get the concept of the X and/or H pipe. if someone could clarify itd b grately appreciated

 

+1 on what cyclone429 said, with a couple caveats:

true duals aren't worth it, they do increase performance, but not enough to justify the cost of the system. The Hemi runs well on a single 3" into the muffler with dual 2.25 or 2.5" outlets. The most restrictive part of the system is the factory Y-pipe coming off the collectors, if you want to get near true dual performance for a fraction of the cost, get a magnaflow Y-pipe and the catback of your choice. Kits are always overpriced, any exhaust shop should be able to put in a y-piper, muffler, and tips of your choice run any way you want for the same price or less than the price of just the kit.
