I thought I would start here before posting on the exhaust thread. The oem muffler on the '09 and up is supposedly a straight through design. Does anyone have a internal picture of the oem muffler? Are they similar to a Maggie or Borla?

Thanks.

That's the best picture I could find, it looks straight through with perforations in the pipe to muffle it.

 

F150Aggie,

I assume the newer model muffler is on the right (lower). It looks very similar to a Gibson (SFT) SuperFlow Muffler.

Thanks, James

 

I think they are both the same, just one has the outside cut out to view inside.

 

The one on the left looks like an 04-08 and the one on the right looks like an 09-up.

Looks like a standard turbo-style muffler.

 

I really like how the 09-11 F150's sound from the factory.

 

X2 on the exhaust note.

I can see it just fine.
