Not even going to start a brand war here, just looking for info.
What manufacturers make dual systems for our trucks?
Bunches of single systems out there, but I'm looking for duals.
I know for example;
DPPI
MBRP
Magnaflow
Goerlich
have systems they either build themselves or have made by someone else. All have some differences.
What I would like to do would be to get a header pipe from company "A" 'cause they have this feature. Tailpipes from company "B" cause they have that. Muffler or lack of from company "C" because of this feature, and so on.
It would seem, that a individual could go to these different places and get the parts they want, but it appears that they want to sell the pieces as a complete system. I understand the warranty issues.
Again, I'm not saying that any of the above mentioned companies products are better or worse than any of the others. Just that each one has features that I like and dislike.

shortround: First trouble I see in that is fitting the stuff together- maybe brand a makes the downpipe 2" longer and the next part 1" shorter and the next again 1" shorter than brand b.
Then brand c will make part 3 some 3" shorter than b etc- I think you could end up welding and fabbing a lot.
Second potential trouble I see is the different steels that may be used- electrochemical corrosion can be a bear.
I don't see too much trouble in simply getting the single parts from different companies, maybe you will have to sign a waiver that you know that by the intended use you won't have warranty etc...
I think that DPP had some duals and Rip Rook too- don't know for shure, I like my single better

Maybe it would be cheaper and better to just buy the muffler(s) and go to an exhaust shop that can bend the pipes you want and do it there.
Just my 2c

If you don't want to buy a premade system from one manufactuer, this is excellent advice.
