4" or 5" exhaust ??

OK well i'm looking at exhaust and i notice about a $100 difference between 4" and 5". Going to go with turbo back stright pipe (cat and muffler delete) from diamond eye. Is 4" more than plenty or would i benifit from 5" ? Motor is stock, just plan to add some street/MPG tunes but i tow with it 90% of the time. I dont mind the sound but dont want it to be really annoying like straight pipe 8" stacks. Any advice is appreciated.

EGR Delete Cat Delete
Everything else stock

I'm happy with the 4" diamond eye I put on, not much louder at idle but when you get on it def. sounds nice. I got the muffler on there too, supposedly helps with the drone during towing, but I haven't towed with it yet.

i started out with a 4" turbo back kitty toss and muff delete, but after a while the loudness of the turbo whine and exhaust started to wear on me. i installed the muff that came with the pipe kit and now i am happy with it.
