If your talking about the diameter of the exhaust pipe (not tailpipe) then pretty sure it's 2.5 - might be wrong though

The tailpipe exit is 4" and the connecting pipe is 2.5".

jus while on the subject of the prodrive b.box , if lets say a full turbo back 3 'decat system was in use ,and a lad wanted to go a bit quieter , what would he loose by replacing with a 3>2.5 mid section and a 2.5 prodrive b.box . would a tweak be needed , much power loss ??

any info welcome .

thanks in advance !

He'd definitely lose a lot of noise. I would imagine 8-10hp.
