Can anyone tell me the legnth of the 3" presilencer that comes with the full turbo back exhaust? I need a cat now, and I assume the only way is to have one made. I really don't feel like measuring mine right now. Post up solutions please.

I have the N/A RB exhaust the diameter is different, but I would imagine the length is the same, from flange to flagne not including studs is 20 and 13/16" fat, almost 20 and 7/8".

So what is the deal?

Is the turbo 3" really 8 inches longer than the N/A version?
