Hey guys, I've been a reader for two years but haven't needed to create a thread until now.
I technically don't need ti make it I guess but damn I hate that dodge/ram didn't continue with this trucks production.


I have a 2009 4.7 Dakota SXT. My manifolds were due for replacement so I battled with those and got new OEM ones on. Alot less leaking for a short bit

From there, everything was down hill. The cats were old and due, the mid pipe had a couple holes and the Muffler did as well. The previous owner may have welded in pieces here and there but it was beyond saving.

I purchased a y pipe online (then again at napa with the same description, got the exact same part sp returned one). I bought the mid pipe amd muffler at car quest and kept the tail pipe.



My y pipe did not fit and the diameter is smaller. I assume this changed in 08 with the addition of flex fuel, however I couldn't find a y pipe for my exact truck easily. I found one on partsavatar.com for 1200$ so temporally my flanges have been cut off and replaced with the old ones to fit, an inch was added on either side to clear the length down and almost an inch was added to the width of the y pipe.


I didnt do this work because I was busy and now my y pipe is touching a trans cooling line and the cab floor at the heat shield fabric stuff. My tailpipe is also resting on the diff towards the front of the truck not the back side of it.

i am going to go under the truck tomorrow and raise the tailpipe end up with the exhaust hanger on it (adjustable) and hopefully there isn't to much tension on the metal back to the Y pipe.



But long story short my problem lies there. Wtf can I do to this truck to get it back to good proper shape. I cant even find a cat delete that fits it because they all list the entire generation not specifically the flex fuel sxt 08+ models with the larger piping and larger flanges and slightly different geometry.

I ran into this issue as I put the 2008 heads on my 2007 truck. They are 3 in outlet vs 2.5in outlet. Your best bet is going to be to take it to a reputable exhaust shop. Tell them the issue and just have them build a full custom exhaust. You will have to have cats installed as it is in fact illegal to remove them and a good exhaust shop simply wont do it. But as long as the ones you have are in good shape they should be able to re-use them. Be prepared to drop between 1000-1500 for a full build but it may be the only way to get it right.

Here's my suggestion, similar to my situation a while back. I had to replace a cracked exhaust manifold, so I ordered both sides new. My cats were shot, so I ordered a Magnaflow Cat & Y-pipe (Federal/EPA Compliant / Magnaflow 49463 system), which fills in from the exhaust manifold to my existing Borla Cat back exhaust system. That fills out the whole system perfectly.

One Magnaflow Cat & Y-pipe system that fits your truck is HERE, mine was cheaper back when I ordered. You'll have to see if you need a Federal or California compliant system for your truck. There is a sticker on your truck which states what system you'll need. I believe Canada will be a Federal Compliant system

Follow that up with the Cat Back system of your choice, and you'll be all set.
