Exhaust question on a 7.3 super duty.

Yellow1000 · Oct 25, 2013

Buddy of mine wants to hear his truck a little more , on the cheap side of things. Can we just use a 3.5 inch resonator in place of the muffler as still not have it to loud or have any drone?

I've got a 4" MBRP resonator on my 03, and it sounds awesome.
No drone, not overly loud, and has a decently throaty tone.

That's all he wants to do , his is an 01. We figured a 3.5 inch so it welds right in.

Should sound pretty nice, not too loud at all.

The stock exhaust straight has to me a god awful cackle. The resonator should help control that some.

Yea that cackle or chop is what he wants to tone down a bit. Thanks guys. Any suggestions on where to buy ?

I would suggest an Aeroturbine... a bit more money, but the best resonator money can buy.

Also helps to lower EGT's by 50+-*...

Personally, I'd just go out and get a full exhaust system, instead of just the resonator.
I got a 4" turbo back from MBRP, tip included, for like $350.
Can't go wrong a bigger exhaust on a 7.3. :ford:

Like where a cackling sound comes from. All I ever hear is a nice flutter. When you say cackle I think of jackasses on harleys with straight pipes that hold every gear wot for 4 seconds before they shift just to hear themselves...

They made a fairly funny episode of south park about "biker fags"

I have had stock straight piped, 4" straight pipe and now I have Flo-Pro 5" with muffler and it's by far the best exhaust I have ever heard or installed.

ANSA Silverline 4" muffler that came in my kit. Summit Racing has a unreal price if $123 free shipping. UDM1409 . Polished T409 stainless steel. Sounds very good.

Stock straightpiped sounds hideous. Too much raspy crackle/flutter. No real sound, sorta like a wet fart.

4" turbo back with a muffler...can't go wrong, they about all sound the same honestly.
