6.4 exhaust on a 6.0

Sixleaker4 · Jun 19, 2019

Like the title says I have a buddy getting rid of a 5 inch exhaust from his 6.4, will it bolt up to my 05 6.0?

Be “made to work”, yes.

“Bolt up”... no

How hard would it be to “make it work”

I did a filter back 6.4 exhaust on my 05 because I wanted the dual outlets behind the passengers side tire.
Nothing fit correctly.
By the time I got finished with it, and had it tucked up and in like it needs to be it would have been just as easy to build it from scratch.

You’d be better off building it from scratch with a universal/builders kit.

Then again, a p1 exhaust is only a couple hundred bucks, you’re not gonna save that much building everything yourself.

Ok thanks for the info guys

Is it just a matter of relocating hangers? or does it just not fit?

Hangers are all in the wrong spots and the downpipe won’t bolt up

My biggest issues were the hangers were wrong, the tailpipes dropped the tips way too low, they also stuck out way too far, and the dual 3.5” over axle pipes didn’t fit nicely.
Just buy a 6.0 exhaust and be done.
I liked the dual tip look, and my single cab will get the same style, but I’ll build it myself instead of buying something and completely re-engineering it.

Yeah I put a 4” aftermarket 6.4 exhaust on an obs 7.3 a few years ago. Had to do some cutting an repositioning to get it to look right behind the axle.

I recently bought another 4” aftermarket 6.4 exhaust to put under the SD 7.3. It’s going to take fab work for sure but for what I gave for it, I couldn’t have bought all the individual bends and pieces to build one from scratch.

I’ve got enough pieces now, all I’ll have to buy is the tips. LOL
