| I finally got around to installing my new Specialty-Z Catback (full stainless, dual tips and resonated X-pipe). Very high quality product. It is replacing my B&B X-pipe and stock Nissan mufflers. When I picked up my exhaust from Greg Dupree back in early January, he showed me something interesting. The following pictures are comparing the B&B X-pipe and the Specialty-Z X-pipe. Picture here is the cross-over in the B&B x-pipe. You can see the hole is fairly small, circled in red. 
The next two pictures show the cross over in the Specialty-Z resonated X-pipe, again circled in red. 

Big difference, no?
A side by side shot:
 Haven't driven the car yet, it's still winter here and the roads have lots of gravel and sand that needs to be cleaned up. I can't wait!
Thanks to VorpalZ and Red Z32TT for their help!
