Hey Guys, I'm hoping to get a muffler put on my 3v 4.6 EXPLORER tomorrow. I'm assuming exhaust-wise we would be setup pretty similar.

What Muffler are you running and how is the interior drone? That is my #1 concern with this. I am driving 1000 miles on Sunday and I don't want to hate my truck by the end of the trip.

The Best way I can put my idea is, when I hear ENGINE NOISE, I want to hear my exhaust as well, but when the engine is quite, the exhaust should be quite as well.

 

granted i dont have the DOHC 4.6, or a 4.6 for that matter, i have a flowmaster 50 series SUV muffler on my v6. its mellow at idle, but when you get on the throttle you hear the exhaust. maybe someone could back me up on this, also you could probably youtube a video of it if you search.

 

Well mines loud all the time, and it's a 40. You might want to go with a Magnaflow or a 50 series.

 

Wanna hear only a slight hum? Magnaflow 18", wanna hear it on acceleration and faintly on highway with the a/c and music off? Magnaflow 14"

 

Just do a swap out for a Magnaflow 14" I think you'd be happy for sure. That's what I did first on my truck, had a nice deep tone compared to stock, didn't bother my wife at all

 

I had a Spintech on my 4.6 Expedition. I loved that thing. It was kind of loud through the city but got really quiet at highway speeds.
