From what I've read...the farther upstream the better.

 

I have the 4" FTE (30" version) with my Magnaflow 4" exhaust. It definitely took the edge off my drone at 17 to 19k RPM but it's still there and gets on my nerves big time. I have the super cab short bed.

Like the other post mentioned, it needs to be up as close to the down pipe as possible. The best I could do was right after the Tranny cross member.

Rich,

Is your resonator right off the down pipe? I can't fit mine right off the DP.

From the hours of reading I have done, it has a lot to do with the length of your tail pipe after the muffler. Soooo, I removed the last part of my tail pipe and added a short 8" piece cut at an angle. It's a short term fix but at least I now have no drone until I can work up a solution. And yes, I live in the salt belt.

 

I have read the same thing about being as far upstream as possible. I can get it to within 18" of the vertical portion of the down pipe. The little s bend in the pipe prohibits getting closer.

Hey look at that. It only took me 13 years here to hit 300 posts!!!!

 

Congrats on post 300!

Mine is under the passenger seat/foot area. It's as close to the DP as practical.

 

Without pics Rich....it never happened.

 

Cut me some slack, dude. My camera wore out months ago, and I finally recovered from the one-arm bandits in Reno, the many arms out at Christmas, and Stinky twisting my arm for years.

I just Buck$Zooka blasted at some tech this week, and it included a new camera with HS capability - so I'm back in the game.

 

I've been reading and watching.

Just picked up 02 7.3L Excursion Limited last week and looking to upgrade exhaust from factory to 4" but want it with no drone (have Series 44 in my 4Runner= D.R.O.N.E) and very quiet inside.

This is to be our long haul vehicle, camping, etc, so quiet is very good.

Along with it, looking to add Ford AIS, FRx, HPx, and Hydra. Possibly John Wood VB. Maybe even a Wicked Wheel 2 to move boost and torque lower in the RPMs. All things in balance, so I'm listing them

Not looking to mod crazy, just that extra kick in the pants for daily driver, long trips, and towing camper long distances.

I don't want to continue to do exhaust work here in the salt-n-rust state, so stainless for me. Shiny is nice, but I can live with a pretty tailpipe end. LOL.

I was thinking Diamond Eye quiet tone downpipe, FTE resonator, then...??

I would like to buy it within the next 2 weeks.

Any help to avoid throwing away $$ for disappointment would be much appreciated!

Oh- and am I correct, that I *should* be changing to 4" exhaust with these other mods?

I would be satisfied with 1000.0 rwhp, but probably settle for 400 hp. haha

 

I don't see a Diamond Eye Quiet Tone downpipe for the Ford. The MBRP that I put in is tight enough as it is, I can't see bigger going in without some massaging of the firewall.

 

Here's a link to the downpipe. What do you think?

99-02 Ford Powerstroke Downpipe

I haven't climbed into, around, on top of the engine yet. It's quite high and I can't get it in my garage at the moment, so I can't say what it is or isn't yet.

 

That's a standard downpipe.

 

Ah, yes. It isn't the quiet tone. I am new to modding onroad diesels. I'm just getting a sense of the sites and offerings.

Maybe they don't have a quiet tone because of the space?

I thought the quiet tone was just a thicker walled with ceramic coating? Is it that much larger?

(Don't be afraid to set me straight, that's why I'm posting here )

 

What I gathered from looking at the Quiet Tone for the D-Max is that it is built like a resonator.

 

Well, its been a busy couple of weeks but the truck is done and running like a champ!





Here is the resonator. Just got it on today. Doesnt make too much of a noticeable difference





The new S&B intake. HUGE difference with noise. Between it and the resonator, I can mainly just hear the tire noise. Very little drone left at around 80mph





The old transmission ready to be shipped back.





The new JW tranny, snug as a bug.





Truck getting ready for the new cooler.





This thing is HUGE compared to the factory trans cooler!!

So a very busy and EXPENSIVE couple of weeks....... But she's back on the road and better than new!

 

I watched the muffler shop install the resonator on the truck, and I didn't realize how far back it was until I really looked. It's more under the rear passenger foot well, but before the muffler.

 

The one I got is 30" long! It connects directly to the 4 to 5 inch adapter on the tailpipe.
