I have a 1998 5.4L and i want to add a little more growl to my exhaust and definately don't want to lose any HP or TQ. Can you just replace the muffler and the tail pipe section?
Kinda like a Muffler-back system?
Because i do want duals but i'm 16 and i'm on a little tighter of a budget.
Also, i heard that the Flowmaster's sound really great and i want a awesome sound but i don't want to have it annoy someone every time i accelerate, just want to notice a rumble.
Thanks, FlaresideBeast
P.S. i also heard that the Flowmaster's make you lose HP and TQ, is this true? should i look at MagnaFlow's? Thanks

Yes, you can replace any part of the exhaust; muffler and rearward is fine. See what your local shop will do it for, then check to see if that is cheaper than a cat-back kit. With the multi-cat setup your truck has, you have to get a loud muffler to get much sound. Flowmasters do sound good; their website gives sound graphs.

Howdy!

I did notice a slight increase in power, just by the "feel" of it.

Hmmm.. I dunno about Flowmaster Delta Flows being the "by far the best sounding flowmaster"s.

"What?!" "I can't hear nothing!" "Is that a Flowmaster under there?!"

Have a high-flow day.

My ride:

Basics:
- '99 XLT F-150

Under hood and back:
- Ram air (Don't ask me how )
- AiRaid intake
- Flowmaster DF 50 Series
- 24x3.5" Stainless steel slashed tips (Yes! Solid polished SS, no cheesy chrome-plated)
...

Outside:
- Precision polished billet grille and plate holders
- American Racing 17x8s polished Pythons (Flushed front AND back)
- Goodyear.. something tires (Expensive is all I know. LOL. No Firestone firecrackers for me either)
- Rhino liner
- Ford nerf bars
- Ford bed rails
...

Inside:
- My girlfriend!
...

Fun stuff:
- Dual sirens Black Widow alarm system/keyless entry (Enough decibels to go deaf in a garage )
- Custom driving lights (Just a cool blue)
- 2 High-Watt lights behind grille (For people who cut me off )
- Dual horns (For people who, again, cut me off)
- Dual wheel locks (So I won't be driving home on bricks!)
- Spare wheel lock (So I won't have to use a brick as a spare )
...

Best of all:
- Texas A&M University aTm front plate! Gig'em Aggies!!
