Do the GT500 stock mufflers have a better flow rate then '07-'09? Louder?

 

They do have the larger 4" tip, didn't know if internal piping/baffling was larger as well?

 

Also, would anyone know the Ford part number for the 2010 mufflers, should be on bottom of muffler and start with F-1-?

As someone already said, they are louder.

 

I know the tips are 1" LONGER but I don't remember them being larger ID/OD. I can check for you if you like (I have mine on the top shelf in my garage).

 

I can also look for a P/N when I check the tips. I don't remember seeing one on there though. Paper label? Stamped number???

 

I'm off to the State fair but I'll try to remember later when I get home.

 

Ping me privately to remind me, if I don't reply soon;
