I have a 2005 5.4 FX4 and I just wanted to let everyone know I put it on last night and HIGHLY recommend it. Never heard a better sounding exhaust on a 5.4. Deep and Throaty but calm on the highway. Usually I dont notice that much of a torque and gain in an exhaust but you can definitely feel the increase and itsthe only mod on my truck. I'll try and get some pictures up soon! If your looking for an exhaust for your truck seriously consider this one!

 

very good to hear! do you have a si/do or di/do or what?

 

what exhaust did you get? I see its MBRP but is there more info. Also instead just pictures, get a video, the pictures won't do justice. We're going to have to hear it!

 

I'll get a video up tommorow. Its a single inlet dual outlet catback system. Dual split side exhaust!

 

Im thinking of changing my exhaust. I have the flowmaster 50 series on it now, but want something deeper. I already have SI/DO so all I would need is just cut out the old one, and weld in the new one.

 

I have the Super 40 2.5"SI/3"DO w/ 3.5" Long tips on my 4.6 and everyone asks if I have the 5.4L. Its throaty idling, setting off every car alarm in the lot ( ) but its quiet enough to hear the radio with minimal volume while cruising. Hope that helps!

 

I cant wait till my mbrp comes in seems like everyone is getting it now.
