hey, ive been thinking of mocking up a 4" exhaust for my s2000, im using a pfab log topmount and a precision billet 6265 turbo with 3" vband outlet.. im just wondering if you guys think this will fit without hitting the firewall with the turbo mounted:

im debating on purchasing it and looking for suggestions. thanks in advance.

 

3" on a topmount is very tight. Id be surprised if you can fit a 4" with that manifold.
