Are you talking about the system? if so 2 3/8"(60mm) to 2 1/2"(63.5mm) you dont want it any bigger than that.

I don't understand. I also got 156 3.0 v6.
At first 2 pipes (60mm each) and than 1 pipe with only 63,5 mm?

Re: 156 3.0V6 Exhaust piping??

where the 2 pipes ( one from each side ) meet as one, it should go from 54mm-57mm with the 2 pipes(these are secondarys) into the system( one pipe ) this should be about 63mm. If these pipes are bigger it over kill and wont be giving any more power. This is all providing your car doesnt have more than about 280hp then you could use a 70mm system. its not all set in concrete tho.
