I have a 2000 F-150 with the 5.4L and I am looking at dual exhaust systems from JEGS or SUMMIT RACING that do not have mufflers. Is this the best way to get good sound and will I lose power by doing this. Also it says that for those kits the spare tire must be relocated. Is this true.

 

If you want loud, take a look at https://www.f150online.com/forums/sh...hreadid=108869

familyman put on True Duals w/ glass packs on his truck.
He had it done at a local Muffler shop, and did not note moving the spare tire. That should not be required if the shop knows what they are doing, and if you have a 16" spare. If you have a 17" spare, need to check on it.

The other option is to do true duals, forward dumps ( in front of the rear tire pass side ), no worries about the spare.

Either way when you take out the stock Y pipe, make sure to do up to the X pipe all in 16 ga 304 SS pipe. Don't skimp here with aluminized pipe, the heat loss can hurt the flow rate of the chst gas.
Mind you these are duals from the cat dumps back. If you were looking for a SI/DO system, ignore the Y to X pipe conversion part, the dump location is still the same options.

For amplification of the sound, go with 3.5" tips on the system, it seems to help increase the noise level more then the 2.5" dump.

Sounds pretty good.

 

With the loss of back pressure you could end up burnin out your valves with no mufflers. I would go with some good toned glasspacks if you want loud. True duals with 12 inch packs and tips should get it done.

 

If you want loud an obnoxious go with Flowmaster forget the glasspacks they have to much restriction in my opinion for your truck. They will backfire and pop like crazy upon decelration.

For anyone considering dual aluminized tail pipes, I recommend the Magnaflow mandrel bent ones. They work around the 17" spare tire, are mandrel bent for the best flow, and are cheap at about $85 for the pair.

 

APT, where can I order those mandrel bent exhaust pipes for $85.

 

Go listen to my clips on my website. This is a Y pipe after my cats, with 2.25" pipes all the way back to 18" 3.5" slash cut tips.

Now I am running true duals (2.5") straights with rolled cut stainless tips at 45 degree angle out the sides.


The 2.5" straights are bad a$$ sounding. I'll record as soon as I can get ahold of my brothers hand held computer..

Intel486 just had a pipe put in place of his muffler on his 4.6, for like $35, and his truck is pretty damn loud. No drone in the cab, but if you are following him, or standing on the side of the street, you know he is coming.

 

Magnaflow universal tail pipes #15019/15020 for $80 plus shipping. Have them bent for side exit if you'd like.

 

With those Magnaflow dual tail pipes will i need to buy a y-pipe also? And where can i get a good deal on one?

 

It depends on what you wnat to do. The stock system has 2 headers, two cats per side, then they are joined into a single 2.5" pipe, though the muffler, and out the single tail pipe. If you wnat to remove the stock muffler, put in a y-pipe, then use these tail pipes, you can. Big Exhaust also sells Flowmaster and Magnaflow y-pipes both of which are good designs for reasonably prices, under installation accessories I believe. Or, you can cut out the factory y-pipe, run two new pipes up to these tail pipes. True dual with no mufflers.

Lots of options....
