F-150 Glasspacks?

[waligators]

I own a 2003 Ford F-150 5.4 and I'm looking to get that popping, crackling sound out of my exhaust when I'm accelerating. I have a Y pipe going into dual exhaust now with 2.5 inch pipes and 4 inch tips at a 90 degree angle out the back with no glasspack or muffler. What can I do to get this sound? I don't want to cut the cats off because of emissions. Is it best to run two glasspacks or just one? What kind of glasspacks sound the best? I've searched the net and it seems packs are the way to go to get that kind of sound...

The better but not necessarily cheaper (not to mention legal ) solution would be to tear everything out especially the Y-pipe and start new. True duals sound much better than any Y-pipe setup. 3" pipe, skip the cat, throw an X-pipe in there to even everything out, throw in a couple glass packs and keep the tips you already have. As I said, this is not the most legal route to take but in my opinion it would be the best sounding option. You can leave the cat in to be legal but it wouldnt sound as good.

Just my .02

That might be great for sound...as long as drive-ability, performance, mileage and a full time check engine light dont matter to you.

Get a cd of loud exhaust and play it in your truck cd player. Then you will have the best sound ever, and as loud as you want it, and no one else has to listen to it.

Let me tell you, I really admire the neighbor kids loud exhaust at 2 am when he comes home from partying everynight

Ya, I am getting old

That is the exact same setup I had in my '96 Silverado. The difference in mileage was negligible. As far as the performance, it seemed to breathe better with the above setup and a set of headers and a different intake. Not sure what you mean as to the drivability, it ran like a top and drove just fine. And I dont care about the check engine light, every car I owned before that had the light on.

Eliminating the O2 sensors will eliminate the computers control over injector pulse width, and the computer doesnt know if the engine is running to rich, or to lean. Therefore as a default, it goes to a slightly rich state, and that alone will cause less fuel economy. In the older vehicles, it isnt a big deal, in the the newer vehicles, it is.

[Macgyver55]

There isnt much sense in trying to convince you since you have your mind made up.

Suffice to say that a great deal of your performance is determined by what the upstream and downstream O2 sensors on the converter "read" from the exhaust. This also determines how much fuel is delivered by the injectors which in turn delivers the best performance.

When the sensors are rendered useless by removing the converter you will never achieve peak performance, mileage or emissions no matter how "powerful" it might sound.

[c0untryf1sh3r]

I know where you guys are coming from. I've turned my fair share of wrenches. When I had my Silverado I didnt care so much about the mileage but more about how it sounded, and I wasnt pulling anything heavier than my tin can '79 Crestliner so it worked for me. I didnt say the guy had to take my advice, I just gave him my opinion on how to achieve the sound the he wanted. But I digress.

Back to the original topic. What would you guys suggest he do then? Since my idea got blown outta the water faster than a pack of dogs on a 3 legged cat

[Scott K]

There isnt much you can do, right now the cats are intact, and preventing the cackle/rapp you are looking for. You either have to illegally remove them, or deal with the quiter exhaust.

I have an 02' with straight duals all the way back. You can really hear the cracking which I like and am very used to by now I have had it since I bought the truck in 07' let me know where your located and I could look the place up that did it was cheap if I remember and he did a good job just a small place.

I really never understood the point of being loud, I love the fact that when my Trailblazer is idling you basically cannot hear it at all. You exhaust guys should explain your fascination to the rest of us

[TR21HP]

Agreed Brian6715, Putting loud exhausts on an automatic is like putting lipstick on a pig, regardless if it's a truck or not. It's almost as bad as listening to the 4 and 6 bangers out there with the fart tubes on. Give me a large V8 with a stick and then put some exhausts on and you have something but that drone of an automatic as it goes through the gears with exhausts doesn't make sense IMO.

x2 The Harley guys can chime in here as well?

I love the sound of a tuned motor but plain loud pipes are a pain in the Arse or ears.. I used to love when the pullin tractors with the 5 keith Black big blocks would crank it up..

but as I get older its not as much as it is a novelity

Its kinda like how some kids like the BASS sound. I just like rock and roll

I have a Bumber sticker that reads "If you can't make it fast Make It LOUD" I met the guy that had them made and he said that he was tired of all the neighborhood kids with the loud pipes with no perofmance motor in their rigs.

This guy was a Auto body guy and the other sticker he made was "Body by MNDOT"

There are different ways to achive that rap sound but most of them invole doing something illegal and its not the best opinion to give.

[JOHNBIGDOG]

My Horn on my motorcycle sounds gay, I prefer to give the engine a rap. It usually gets more attention. (08 Suzuki gsx650F with a Yosh. slip on)

On a Automobile there is no point in having a loud exhaust unless it is "Tuned" to the engine in front of it.

* Note if I had a quieter exhaust I would have to hard wire my horn ON because there are too many people that only look for cars, not that small motorcycle they are merging into........ Actually a Harley is not to loud to the rider, but get behind one of those guys and it gets annoying.

[dan z]

If its a performance upgrade I don't mind the rumble but if its stupid high school chop shop exhaust it sounds RETARDED especially on half ton trucks with wuss a$$ automatics

I can make my truck rap rap in any gear cuz it takes two feet to drive

[K_Josh87]

jeese, flog the guy for wantin some pipes... haha...

[TR21HP]

With the total unattentive drivers out there if I had a bike it would be loud. I've almost been run into by drivers on the phone when I'm in my truck and you are taking your life in your hands on a bike nowadays. Again, if it's on a stick with a nice V8 behind it I really like the sound but that drone of the automatic as it goes through the gears doesn't sound good at all.

[Tator2k]

checkout the f150online forum. There's a ton of info and comparisons for you.

[TR21HP]

Actually a magnaflow cat back system would give you a really nice sound and not that sharp, abrasive sound that flowmasters or others give you.

Two years ago this May a guy in our neighborhood either put a louder exhust system on his PU or he just didn't fix a bad one. He must have worked evenings as you couldn't miss hearing him come home around midnight. In a few conversations I had with neighbors the subject of his loud truck came up and it wasn't compliments being made. By the end of June the truck was quiet again. I'm pretty sure someone complained to the PD and they took care of it. Before you spend money to make more niose consider you may need to spend some more again to make it quiet if neighbors don't appriciate your choices.
