Is there a factory or aftermarket piece that ties the dual outlet exhaust on a set of 4.9 manifolds? Or, is this a fab it job at the local muffler shop.

 

Oh, I intend to keep the original single pipe.

 

There is a factory one. I believe I've found it before on summitracing, or a place like it.

If you're looking for an aftermarket, it's Walker converter pipe WLK-45166. It's 2.5" though.

 

Look at a magnaflow 93302. It's a little spendy but it's good quality, works and looks great, was easy to install, and comes with a catalytic converter. I used it to plumb back the exhaust on a 1985 f-250 I put EFI manifolds on. There are a couple different sellers of it on eBay. The first seller rejected my offer of $205 but the second one I offered $205 to accepted it, with free shipping too. Just something to consider.

 

No cat on mine. Bought it that way, farm truck.

Need just the Y pipe assy to join the two together. Have to double check but belive I already have 2 1/2 exhaust. Muffler shop here is known for probloms. Bad workmanship. Not standing behind their products and jiping people. I intend to take it to them but if they give me any grief about a cat I will hop in my truck and drive out with them half done.

 

If you don't need a cat, and already have 2 1/2" exhaust, then just grab the walker 45166. I think they're about $75. You may even get a local parts store to get it in for you.

Dynomax Performance 45166 -

There's no pictures, but that's the one I bought and it bolted up perfectly.



It's the one on top.
