The only real difference is the 5in has a better tone then the 4in IMHO. Other then that just the fact of saying you have a 5in, there is no real performance gain unless you plan on pushing out 500HP.
I just ordered 4" aluminized turbo back duals today, $425 shipped. I can get you the info if you are interested. You can probably save another $20 if you want a straight pipe.
That sound clip sounds like a friggin 747 jumbo jet driving by. I wish I had 5" but I'm happy with the 4" that I have. I also bought a RBP 18"L x 6" Tip and I couldn't believe the difference in sound. Totally different.
I ordered from www.dieselpowerproducts.com with a price match from www.modsfortrucks.com. The system I ordered is Diamond Eye and the shop is only about 6 hours from my house so I should have it tomorrow, can't wait! Hoping to find a good deal on tips and add them later, I was floored at the cost of tips!
Well my money is all spent now- guages and exhaust are both on the way Got a good deal on the gauges too- $300 for a never installed Diesel Manor Isspro 3 gauge setup with tap, drill bit, and spray paint.
You got a good deal all the way around Chase, the PMS has begun

The bad thing is, I had PMS before I even had a PSD! Next up is the DP tuner and/or BTS valve body for the trans, oh and getting the rear rotors turned
