I purchased a Silverline 5" stainless from a vendor on eBay. He has them advertised as a buy it now for $475 including shipping. I made an offer for $450 and the exhaust is on it way to my house.

DS107409 5" turbo back stainless exhaust. It was the best exhaust for the money I could find. Check them out....
Search eBay for
SILVERLINE 5" STAINLESS EXHAUST-04-07 DODGE CUMMINS
Here is the link in case that will work
http://cgi.ebay.com/ebaymotors/ws/eB...m=120191094950

The exhaust went on very easy and sounds good. Much loader than stock. I purchased the 5" as I have a Silver 62 turbo on order and thought it would like to breathe easy.

Merry Xmas, Jeff

I like the 4" better.. To each his own. My truck had a 5" on it when I got it.
It had a raspy sound. Droned something awful at highway speed. Changed it out for an 4" MBRP system. The 4" sounds much better, a mellow tone without the droning.

I went w/ the 4" MBRP turbo back system. Plenty of flow for me and not as loud as some 5'ers I know. But that's just me. Kurt

I bought a 4" magna flow stainless for 366US(free shipping) delivered to my door and I live in Canada.! It was a quick and easy install, came with all clamps and hangers pre-welded in place.
I bought from HottExhaust, they have a parent company in Toronto

I have a 5" MBRP and with the muffler I thought it was as quiet as the many 4" MBRP's that I have put on but just a little deeper so i took the muffler off. Not realy any drone but realy deep and loud on the outside.

I put a 4 inch straight pipe kit ) no muffler) on my truck for price reasons. I was able to get it to my door for under $300. That was the only reason. I just did not want to spend that much on an exhaust system. It turns out that I am real happy with it. A little bit of a drone at exactly 2000 rpm, but 100 rpm either way and the drone goes away. I am very happy with the 4 inch and will not replace it until I get the bigger turbo and need it...

Go with the 5". It looks cooler when someone gets under your truck.

I put 5 inch on my truck...4 inch is alright if youre just gonna do an intake and a programer but I'd eventually like to add injectors, charger, and some head work so I went with 5 inch from shopdiesel.com....$310 for 5" turbo back kit with muffler delete pipe and 4" down pipe and free shipping. I was just planning for the future...but reguardless the 5" is bigger than 4" and in my oppinion looks cooler.

i just put in a magnaflow ss 4" no probs, but it drones slightly at 2100 rpms, but idk. no need for 5" unless your going over 400hp, imo.
