On the prodrive back box on a newage,does any one know if it's 3inch or 2.5inch?

 

2.5

 

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".

 

Yea the connecting end, thanks for the quick answers, cheers.

 

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.
