isnt there two different greddy exhaust versions? if there is can someone tell the differences. and if they really matter? looking at a used exhaust but i dont know if it is the new or *old* version. really matter?

 

As far as i know there are 2: the sp2 and the TT (link below) Not sure about old/new versions.
Im sure the one you are thinking of gettin is the sp2, which is silver rolled tips vs. the blue burnt tips of the titanium tips of TT. Differences are listed in link.
