Exhaust Systems for a 66-67 B-body with a 440 .

I have a 440 built with indy sr heads i had to buy the TTI step headers and i got 3 1/2 collectors i will be going down to 3" system who out here has done that already and do you have any good pics.!

i used the ttio header back system in 3 inch and i have had no issues, lil bit tight aroung axle/spring but no contact yet.
