ROOSTER_STX06

Hey guys I have a 2006 f150 stx and thinking about putting exhaust on and have always had Flowmaster on all vehicles, but I'm kinda leaning towards Borla Turn downs. Let me know what ya'll think about the two.

I've always had Flowmasters as well. My favorite so far has been the Super 44s. Can't beat that wide open sound when they're dumped.

If you don't like drone, chambered mufflers and turn downs aren't the way to go. Borla is always a good choice for these engines.

Basically i want something that sounds great but gives me a little extra horsepower. I heard the turndowns and they sound pretty sweet, but i just dont know considering i only have a 4.6l v8

might sound like a mustang

Put this on my FX4 the other day. Had to add a 9 inch piece of pipe to extend it and trim the heat shield by the muffler to get to the hanger. Other than that fit perfect. I got it for $150.00 shipped because they were running an auction also. Worth every penny. And it comes with everything you need. Sounds great and no drone, the turn downs are still hidden but just in front of the rear bumper. I'll try to get some pics if interested tomorrow. Just got another mess of snow and rain today.

Remove the stock Y with aftermarket and go 3" single or X pipe with 2.25" pipe for duals. Either way straight through muffler(s) ( ie. Borla, Magnaflow, Dynomax bullet) will be the best way to go for a little hp.

If your considering borla, think about magnaflows if your looking to save some money, almost identical sound, few differences here and there but for some every dollar counts

with your 4.6 you should go for this:

2.25 dual exhaust
2.25" high flow cats
2.25" x-pipe
2.25" mufflers
2 tips of your choice

I have a 4.6 as well and i did a true dual set up 2.5 inch pipe flowmaster 40 series with a 45 degree and downturn at the back. looks great and the sound is amazing. I was debating between the flows and borla and went with flows.
check out this link it helped me. mine have good sound and a deeper burble from back pressure
