ARH true dual, or to not...

[Maine-iac]

So I've done some research on the forum and am looking for some advice. I'm planning to put ARH 1-3/4"and catted Y-pipe on my 14' Sierra 5.3. Most likely looking into magnaflow for a deeper roar. A BlackBear Autocal will be associating the system(bye bye warranty with only 20k miles on!). I currently just have a 3rd cat-back straight pipe y-piped to dual angled rear exits. I've been very interested in making the system true dual. If I were to go the true dual route would the muffle shop have to remove the y-pipe after the cats and fabricate the true duals from there? Or is there a catted option that's not y-piped?

Another question. Should I even go true dual? I'm looking for the most performance. If I'm better off with the catted y-pipe to the dual exits than so be it, but if true dual will bump up my numbers than I'm all for it. I have a feeling that true dual might be too much flow therefore I'm loosing the low end torque I'm looking for. Thank you for any input.

True Dual pipes SUCK and sound like SHIT!!!! 2 into 1 will make plenty of power for your truck.

IMO I say stick with OEM style, unless your going full power with SC or TC, then stay OEM style, its all bolt up simple design, saves money in the end so you don't have to redo your cat-back, I bet you get drone with ARH and Magnaflow. Along with your tune those rear o2 sensors will fire for sure over time normally last about 12 months or less then efficiently codes start or heater issues.

Been a long time since I have had true dual exhaust. Personally, if done right (balanced), I like the way they sound. A slightly modified 5.3 is not going to notice the difference. CAT's are another thing to consider if you are planning on keeping it legal - you may find you need a total of 4 if you go dual.

 

As far as how the shop would go about it, depends on what you want to spend. The main advantage to duals is balance, and the main advantage to custom is fewest bends. You can still pay for custom and end up with neither -- you need a good shop.

 

The "issue" with dual exhaust on a modern truck is really the gas tank. So unless you plan on relocating, your only options are some bad option that includes running the pipes either outside the frame, under the tank, or all down the same side (effectively killing any possibility of it being balanced), you may as well stick with a Y pipe to 3" or greater exhaust.

I appreciate the replies guys. I will be sticking with headers to a catted y-pipe. Now all I need to do is swallow the lump in my throat and fork up the $1700 for the pair....unless there's someplace with a better price I don't know about?? Other than the manufacturer website itself.
