exhaust questions
Just got back from the exhaust shop. First of all let me say I feel like an idiot. When I got to the shop I thought my truck had a 4" system on it. Imagine my surprise when they corrected me and said it was 5". I had them go ahead with removing the muffler. After climbling around my truck (and a few burns), I have confirmed that this is my current set-up:
-AFE Dry Intake
-4" downpipe
-5" exhaust: No cat, no muffler, no nothin
My question is this: My previous truck (chevy 350 gasoline) had backpressure problems with straight-pipes. With no other performance upgrades, will having 5" straight-pipes on a 6.0 cause any problems or should I put the muffler back on? Thanks!

Yes turbo provides all the backpressure you need. In fact in most states the turbo can be considered a "muffler" as well. I know it's that way in NY where I live.
Are you sure you have a 4" downpipe? It's kind of a special order thing only with 6.0's. 3.5" is the standard, 4" is tough to fit, but can be done.

Not many people need a 5" exhaust at all, and 4" is all you need, but it is cool to say you have a 5" It certainly wont hurt anything. I have heard of a few being REALLY close to the spare tire, but I suppose its all how you line up the exhaust.

[QUOTE=Mdub707;595164]Tell me which kit comes with a 4" downpipe... I called MBRP, and the nice lady told me that p/n S6224PLM at $599 is the 4"/5". SPANKED!I know of two companies that actually make and sell them. None of the MBRP kits come with it, they're all 3.5". You should have called them like I didYou can ORDER it though, but most people don't even know about it. 5" isn't anything special order. You can either get 4 or 5. Nothing special about it. You can get 4" turbo backs for $265 and 5" for $295. Without specifically asking for it, you're not going to get a 4" downpipe. I got "spanked"? Interesting. The OEM down tube is 3" NOT 3.5"= SPANKED
