I am intersted to know the piping size, is it mandrel bent, how restricive is the muffler, and how would this exhaust be for a a turbo with the zpi midpipe and s pipe.

I like this exhaust because it looks very stock I am not a big fan of the huge muffler style. However performance is first to me if for a turbo that exhaust is no good with spipe and midpipe then ill get something else.

 

I'm not sure exactly, but I think the Borla axleback is 2.25". I could go measure, but I'm extremely tired right now (I work nights). If you get the Borla setup from TRD Sparks, you will get a straight through muffler, instead of the one that does a 180 degree bend that you see on Ebay. Plus, the one on TRD Sparks is cheaper, and has a smaller muffler. It is mandrel bent, and it sounds awesome!
