hey guys i was wondering if i could get a custom exhaust for my z my ideas on the specs were either dual or single exhaust with 3 to 3.5 inch of piping with the dragger exhaust the piping is so big becouse i will go in the future with FI what do u guys think and suggest

 

I have a custom exhaust done locally here in NC. Check my sig for pics and vid. Sounds awesome and looks great. I think the piping is 2.75" though.
