I have a set of LS7 427 vette exhaust manifolds and I wanted to see if anyone here has ever tried fitting them in a truck before, obviously the collectors are unique but assuming you had them and cut them so you could put on a different y pipe, I think it would be a nice alternative to headers but I'm not sure if it's possible?

 

They would be a nice gain over the stockers and you would still retain OEM sound insulation as well. You'd really need a custom Y pipe though and it would be more of a hassle than it's worth. Also not even sure they'll clear the steering shaft.

I dont think they would be worth the hassle considering the price of longtubes nowadays.

 

X3 you can pick up a nice set of long tubes for around $350
