Hello,

I'm new here and the reason for joining is the plethora of knowledge here. I have a 2013 FX4 (145") Screw. I plan to install a true dual system consisting of 2 1/2 in stainless piping with X-pipe going into a stainless Spintech XL 2 1/2 in DI/DO muffler. The muffler does not have the built in X pipe, it's straight through. I don't like Magnaflow, Flowmaster so that is not an option for me. I should be fine with the single muffler, right?

 

You'll be "fine" with just a single muffler, but what is the end result that you're looking for? Are you looking for max flow/performance or sound? And I believe true duals means two seperate exhaust paths, each with their own muffler, and crossing each other with an X or H pipe. If you're already having to tear apart your Y pipe, and run the dual pipes, you might as well run 2 mufflers

Welcome to the forum!

Edit: sorry, misread your post a little bit and didn't understand that you're running an X with a straight through muffler. Personally I'd still run seperate mufflers, but it depends

 

Thanks for the response. The end game to increase performance. Eventually, I plan to install long tube headers, intake and tuner. To be honest, I drove a Ram for about 12 years and my Ford is a bit anemic compared to my old truck. Don't get me wrong, I enjoy drive it but every now and then I want wow factor when I mash the accelerator.

 

I can completely understand that! I'm ordering my long tubes this weekend because I too need that wow factor. My SIDO sounds so quite now. I'm assuming you have a 5.0? Surprised that you feel that it's a bit sluggish because the new motors make my 5.4 feel like a 4 cylinder haha. But having owned my 2006 for a while now, and my father had an 03 for a long time, the Ford trucks have good power but they're raw and need to be tweaked in order to unleash it. Was your old ram was a 5.7?

 

I have the 5.0 and yes, my ole truck had the 5.7 in it.

 

I'm guessing you have the 5.0? I have an '11 Lariat with the 6.2. I went with Stainlessworks. I have the complete system with long tube headers. The motor was a beast before, but after I had the system installed, WOW. Check them out at www.stainlessworks.net. They are a bit pricey but have excellent stuff. And yea, I hate Flowblunder and magnajunk too...

 

That really is surprising that the 5.7 felt peppier. Old 5.7 vs old 5.4, the 5.7 is noticeably quicker feeling, but wouldn't think that would be the case vs a 5.0. I have a Borla that has been marketed as a Roush, and I like it. It's a good idea to go full stainless depending on where you live, so you sound like you're on the right track, especially because you seem like you'll be keeping the truck for a good amount of time.

I'm sure one of the exhaust gurus will chime in at some point to answer your actual question as to whether the DIDO is equivalent/comparable to seperate mufflers. I know some stuff, but not sure on that.

 

Borla pro XS DI/DO has built in X-pipe, FYI. It is what I am intending on going with. Have to say today is the first day I have seen a member here call Magnaflow junk. Dronemaster I perfectly understand as I own one and don't like it.

 

1muffler will be louder than 2

 

Your not gunna get a performance increase on a 2013 with duals. Not even tru duals. Keep it single 3" that's the best flowing for that truck. If you want an exhaust mod that helps performance get long tube headers and a custom tune to tie it in.
But if you like dual exhaust then just do a y pipe after the muffler to dual 2.5 out.

 

I appreciate all the advice. I will to a reputable exhaust shop just to talk exhaust and he told me that he can install anything I want however, he recommended that I don't install true duals due to losing torque. I think for now that I will just get a nice 3" SI/SO stainless system and later add headers, custom tuner etc.

 

Isn't it already 3" and stainless?

 

Parts are... But you raise a valid point.

Op, in your situation I'd do the following. You say you want headers and si/so. I'd leave all the piping alone and change the muffler only and add a tip. Leave all factory clamps because when you add headers down the road, you can get the full kit that includes the y pipe (catted or off road leads) that way everything is bolt on and mandrel bent. No hack welds or inferior piping. The resonator can be removed but I would absolutely leave the stock piping as is if you just want a simple muffler swap. You save so much headache and cost.

 

I will have to check. The tail pipe look like it may be galvanized.

 

And Scarlet made a great recommendation, SW headers will eventually be sports on my truck. They have great quality products.
