An s475 would be the best in a twin set up like that.

 

How hard is it to build your own twin setup like that

 

The piping is the hard part

 

what exhaust size on that s475

 

T-6 1.32 a/r is the common size.

 

What are you wanting a tow setup or what? BD uses a s366 on the tow setup, but a s475 is the common turbo in most setups. But if this is going on your 07.5 6.7 I wouldnt bother with a s300 primary.
