2005 XLT 4x4 with 4.10LS and 60k here.



I have a DynoMax UltraFlo SS welded muffler. On the stock system. Replacing the stock muffler and the coffice can resonanator removed.



I have the RT y-pipe installed.





Should I go with the RT cat or a full cat-back system?

I actually think your set with the performance end...... Only sound will change if you go with the different exhaust....



Go for something else if you want More performance......

Pretty much done with mod's short of the SC.



Xcal2, c/a intake, your modded tb, maf pipe, coil, wires and sp500 plugs.



Plus all rotors and pads, all shocks, explorer x lowering kit.



Unless there's something I messed. Lol

MAF 3-5 Hp

Under drive pulleys 2-3 hp

Headers 0 hp

Front sway bar

Gears

Forced induction



OR NEW super Six motor and S/C. LOL

Ditto, on ToddZ. Your exhaust is good now.

So what about just doing the Cat and pipe?



Leave the cat-back exhuast untill it's needed, maybe 2 or 3 years down the road.



I already have the MAF.

What The front Sway bar going to do for me?

I'm afraid of the UDP, as I'm running a full sound system with a jbl 400.1 amp, no cap.

And a AVIC-D2, didn't like the D3. lol.



I already have 4.10LS.

I'm getting ride of my topper and putting the Ford bi-fold back on.



So maybe I have to start saving for the SC, :driving:
