Ok heres my problem, i purchased a single magna flow muffler, and now i want to upgrade to dual muff. Could i just purchase a single magna flow muffler or do i have to buy a compete dual set muff ?

 

i purchased this..
4.0L V-6, Axle-back only,
3.5" slash/p-SS tip (Muffler Replacement)

 

No complete set just get another muffler BUT MAKE SURE ITS A DRIVER SIDE ONE and then go to your local muffler shop and tell them you have the mufflers in the trunk and want SS (stainless steel) piping ran for a dual set up. Then there gunna ask you if you want a H pipe or a X pipe or a Ypipe. I'd go with the H pipe if your conserned about sound, X if you want a better flow, minor from whats been said unless you have a supercharger but commen sence will tell ya by looking at the two H X the x pipe will have a better flow of air. Nothing on a dyno from what you all say though and Y is what you already have.

The H or X to be fabbed should only be around $50

oh make sure they weld it on for ya if you have a shop do it not bolt it

 

really appreciate the help bro, but where do i purchase a driver side muffler, cause on magnaflow.coom it says 4.0L V-6, Axle-back only,
3.5" slash/p-SS tip (Muffler Replacement) doesn't say which side.

 

I'd just e-mail em and ask them to sell you one. The will just make sure you state you want the driver side muffler though.

Email them tonight, right now!! lol

 

Yes, and post their reply here! Please! I'm in the same boat, I have a single Magnaflow and would like to go dual.
