Yes the spiral core is a way diff muffler then a bullet is, hell I am surprised nobody said that LOL.. it is a chambered style bullet

 

hmmm

 

Like the others said adding a bullit in front will help

Now to confuse you even more
I had the same problem with my truck LT/corsa sport and it was way to loud..Ended up with putting the stock muffler off the tbss on it and couldnt be happier..Its nt loud in the cab at all,even at WOT its not loud inside

Warm running

Cold start (in the 30's outside)

 

after hearing txsilverado's videos, im doubtful. that seems twice as loud as what i currently have now.

 

Here's the same thing as a Dynomax Bullet, but 1/2 the money...

i dont know, i have exhaust in for sale section now, may just run stock exhaust with 22" magnaflow and see what happens. looking to trade for stock plus cash, so ill ***** my thread out lol. anyone know the stock piping on exhaust?

 

picked up a dynomax bullet from a member on here, so tXsilverado better be right lol

 

On my 6.0 truck,I run the LPP longtubes(pacesetter knock off in SS) with ORY going into a SS 3" JBA Evol exhaust.The muffler is pretty big,26x12x5.When you look in the muffler,you see 2 3" holes that go straight thru to the other side.

This setup is extremely quite except for WOT where it sounds GREAT!Just a mild rumble at idle and no drone/rasp on the highway at cruisng speeds.

I didnt want anything to loud that would still flow/sound great and I think the JBA Evol was a FANTASTIC choice!And pretty cheap too at $400 shipped.
