Not that I really want a muffler, but it came as part of my new DPPI 4" DUAL EXHAUST system.

Thanks to Dennis at Innovative Truck Products. www.itpdiesel.com for the screamin' deal.

I'll let y'all know next week how it sounds, and if there are any performance gains with the twice pipes.

 

What exhaust were you running before, if any?

 

I run a Jardine 3.5" to 4" stepped downpipe, with a 4" straight back.

 

Cool, ordered on the 3rd-on my doorstep on the 5th. Wish I was going to be home Saturday to install.....guess it'll have to wait until Sunday.

 

You living near the geometric center of the country has a few advantages, I'd imagine. Up here in the NW, it seems you're always three time zones and 3000 miles away from the stuff you want shipped.
Let us know how the install goes.

COOL, you need to record this new exhaust sound and share with those of us less fortunate LOL

Quad
Everything I want is in your neck of the woods, 3000 miles and 3 time zones away, so how do we fix this....PSD Express Parts Delivery, AKA, UPS Next Day LOL.

Hey Cookie,

I agree, Dennis at ITP is a great guy and he is very knowledgeable about the PSD accessories he sells through ITP. He uses his personal vehicles as Beta testers for his Ford PSD products, and gone through lots of $$$$$ of miscues in the learning process.

Only one problem, he lives only about 3 miles from me and it is just way too tempting to drop in and see what's new.........

 

Is Quadzilla HIGH!!!!!!!!!!!!!!!!!

Lets think about this a few sec. TYMAR-------- WASHINGTON.

OILGAURD--------- California. Performance Brakes-------Portland, OR. Any thing thats worth buying out there comes from the Left coast. You want torture. Try living in New England, and purchasing a new part from Washinton State, Shipped via UPS Ground. Waiting a week is murder. The vast majority of items r out of the west. Could be worst though. We could live in New Brunswick.

 

You have far more willpower than I do Heatstroked, if I lived that close to Dennis MY truck would be the beta tester.

Have you heard the 6.0 with duals? It quite literally sounds like a jet engine, very cool.

Unfortunately I wouldn't have the first clue how to do that. If you check ITP's web site, he has sound bytes posted there.

 

Well...the install was a bit more of a pain that I had anticipated. Somehow I had allowed myself to forget that installing a downpipe by one's self is not so simple a task, and getting that drivers side tailpipe to match up with the passenger side is a bit tedious, but in all it wasn't too bad.

Some observations.......

It looks sooooooo cool, those two big 5" tips poking out of either corner is the bombdiggity, very badass looking system.

You'll appreciate this Quad. It's quiet. Standing behind the truck you cannot even tell their is a diesel up front, just an ultra low big block sort of rumble. Reminds my of the 429 thunderjet in my old '71 T-bird. Much less noise in the cab too. The up side is when you stand on the loud pedal she really howls, again, just like that old big block Ford. Plus it's cool being able to smoke out both lanes at the same time.

Empirical data.....

I've been told that duals on a diesel are for looks only. I tend to disagree with that assessment. My cruise EGT's are down a solid 50 degrees, and a WOT run from 0 to about 90 mph didn't go over 1050, about a 100 degree improvement. This bad boy moves some air.

Overall...

Aside from it being a little too quiet for my tastes I am extremely satisfied. The DPPI exhaust is definiately top shelf stuff, excellent fit and finish, and ITP was (once again) an absolute pleasure to do business with.
