If it was me I would again do dual smaller pipes inside the bigger ones with glass packs inside the bigger stack and cat there to if I needed one. The only reason I would put glass packs on is to keep the noise down a little because driving down the highway with open pipes makes you wish you lived in town or had a full exhaust plus it helps keep your family a little happier when you roll in at 2 in the morning when the house is not rattling But that is just my two cents.

 

Sadly, the guys that run through residential areas with their jakes on have ruined it for the rest of us. The engine brakes on these new trucks are barely even noticeable. I completely lost air on a 4% hill the other day and would have liked a good jake. Had to hold the tractor air valve in with my fingers to keep the brakes from locking up, cycle the trailer brakes with my palm, steer with my left while downshifting with my left arm.

I agree on not liking the sound of a straight piped gasser too. I had long tubes and straight pipes on my mustang when I first built it. That lasted one trip to the gas station, getting pulled over twice, one noise ordiance ticket and me not being able to hear myself think lol.

 

A few things.

1. Newer fords are WAY louder than old ones... if you liked straight pipes on an old truck, doesn't mean it will sound the same on the new one. It will be WAY louder. Even with the cats on, it will idle way louder than an old truck with straight pipes. I suspect this is from letting the exhaust out earlier than previous gen trucks.

2. The smaller the diameter of pipe, the earlier it will get super loud and snappy, and the louder it will be in total. A 1" pipe might start rapping and snapping just over 1000 RPM's, but a 3" pipe might only snap around 2000-3000 RPM. Again though, it depends on the engine. I've seen this on an old chev; guy ran 1.5" pipes out the back, it was insane loud and rappy. Went to big exhuast, much quieter, but doesn't sound as awesome.

3. A glass pack muffler can control the sound, to a degree. I went from straight pipes, to adding 2 of those cherry bomb mufflers, the kind you can see right through, and they do quiet it down some. I'm not sure, but I suspect the sound would change depending on where in the exhaust they go. I always wanted to try little pipes, but with a few series cherry bomb mufflers.

4. While I don't really care for stacks much, on the right truck they look and sound cool. I like the v8 sound, diesels don't really have it since the exhaust is combined into 1 pipe. I heard a dual exhaust IDI 7.3 once, and it was mouth watering good.

If I tried it again, and went with stacks, I'd run 1.5 to 2" pipes from the headers, up into the 5" stacks, but have 2 or 3 cherry bomb mufflers inside each stack, and in fact, I'd leave the bottom of the stacks open, so that as it was running, would cause a fresh air flow to be suck in the bottom of the stacks, and out the top, to keep the stacks metal temperature lower.
I may be wrong, but I think the little pipes with multiple cherry bomb mufflers would deliver a nice rappy sound, without being insane loud all the time.

 

The problem is that this is a little displacement motor, and it's overhead cab. My friend has a 4.6L that he threw on dual straight pipes and it sounded like crap. It just tings like it hollow. It was more like a puke pipe on a honda. Now my 390 and glasspacks is an orgasmic sound. My 2 cents is don't stack it. But if you do, use a welded flowmaster (I like thrushes) type. They make little displacement engines quieter, but they wake up when you put your foot down

 

I have an old school carbed 289 going into my 89 and my 78 used to have 289 with straight oioes and she sounded good

 

Carbed 289 is a whole different animal than a computerized ohc engine. Still there's a little 283 stuffed in a roadster with straight pipes, sounds tingy. And I got pulled over once until the officer realized I had a grumble rather than a scream. To each their own, but straight pipes echo pretty bad.

 

I used to have straiht pipes on my ext cab duelly 7.3 idi. I put 4 in pipe all the back man she was ficking loud I woke IP the nieghbors every time I went to work at 4:30 in the morning man I miss that truck. I got a piece of 3inch schedule 40 I think it for mynstack picked it up forb10 bucks at the scrap yard this morning

 

The 2v 5.4 sounds horrible straight piped. You can't compare any olde motors to the mod motors. Totally different sound. Look up straight piped mustangs with the 4.6 and the 5.4 sounds even worse then that.

 

I had a 2v 5.4 straight piped and I loved it

 

You have a vanilla ice avatar, so it's obvious you don't know a good sound when you hear one . I'm just teasing you. We each like different things for different reasons

 

Lol vanilla ice was good till he sold out. I put that avatar up when I had my stang and I never changed it lol. Its all good brother.

 

He must have sold out before he released his first track, if that's the case.

 

Lmfao the only track he had worth a damn was ice ice baby

 

Stacks on a gasser? Can I have some of what you smoking?


Anyway there is this. Not a Ford. Dodge

Hmm the image won't show up. Must be an anti-Dodge protection thing

I've seen a few rat rods with gas engines that have stacks on them. I think someone along the way has made stacks with internal baffles (muffler) so it'll be quiet. I looked them up a few years back and I can't remember if they were real or not.

The Dodge Lil Red Express truck more or less immortalized stacks on trucks and everyone else since then has put them on just about anything. I still see no point of dual exhaust on a diesel with a turbocharger on it...you have one down pipe and so most of your exhaust is going out one pipe than the other. At least with a V8 gas engine you can go heads back and have even amounts of exhaust flow.

Vanilla Ice rap of any type belongs in the trash. I'd much rather be driving a Chevy than listen to that garbage. You want good music, how about some old school Metallica, Iron Maiden, Ozzy, Black Sabbath or what about good ole country?
