Hello all, I just got a new to me 2010 FX4. I want to change the muffler for a lil rumble sound. Always been around Flowmasters. What do yall suggest I go with as far as model. I don't want a race car sound but like I said a lil rumble. Thanks in advance.

 

If you'd like a Flowmaster, the 50 series sounds like what you want. A big-bodied (longer) Borla would give the least amount of drone, but are expensive. Magnaflow is a compromise between the two. I'd definitely stick in the 18 to 22" range on the size of the mufflers.

It's hard to judge just how loud you want it, but the mufflers/sizes I've mentioned are relatively quiet, but produce a nice sound.

 

Just what I was gonna say ^^^

 

X3 on Borla. The 19" ProXS will produce a "little" rumble. Don't go with the Flowmaster unless you have had it before and prefer the sound/tone it gives off. Straight through design mufflers do sound better, to me.

 

magnaflow 18 inch. its just the right amount of rumble. not quite but not obnoxious
