So, is it possible to have a 5" downpipe in my truck, or am I stuck with a 4"? I'm really looking for a 5" exhaust system, Turbo back that is 5" all the way. Am I dreaming, or what?

 

You should be able to fit 5" pretty easily.. I haven't seen any major changes!!

 

We have a 5" downpipe on several trucks one we had trouble with the downpipe hitting the trans. fluid dipstick when we were trying to stab the downpipe to the back of its new phat shaft turbo. But it got worked into submission

 

Sweet!

Sooo, Who do I go to for this 5" downpipe? I'm thinking MBRP, but they mentioned a 4" downpipe on their system, like others I have searched...
Do I have to do something custom, or does someone offer it as part of their system?

Thanks guys for the quick response.
I appreciate it!

You can find one here. If you look it up, the sheet shows a 4" downpipe but if you call they will tell you that the 04.5+ models have a 5" downpipe with the 5" kits. I know, I just ordered one after looking at this thread for a few weeks: https://www.dieseltruckresource.com/...d.php?t=172655

 

I ordered my 5" with 5" downpipe from ebay from citymuffler for $340 shipped. Mine fits fine.

 

The MBRP 5" downpipe has a short section of 4" (maybe 4 inches, which doesn't cut down on flow enough to matter because it's 4 inch coming out of the turbo anyway) to clear the tranny dipstick tube. I installed a system on an 07 5.9 auto friday and it fits great and sounds great.

 

Thanks for the info you guys!

 

I have a flo pro 5" on my truck whick fit just fine. the only thing I had to do was since I had a 6" suspension lift on my truck whick drops the transmission about an inch the 5" inch exhause would hit the transmission crossbrace in the truck so I had to lift the transmission back up about an inch and now it fits fine, no touching at all and no vibrations from the front drive shaft at all. It sounds really good too.
