Banks Header

Im looking at getting a Banks headder. I have a 2000 tj with the 4.0 I6. I currently have the headder and downpipe with two (2) pipes comming off the headder. I want to switch this to a single downpipe due to drive shaft conflicts. I put in a High pinion D44 and there is not much clearance between the diff flange and the bottom tube of the downpipe.

So I am wondering if a headder from a 91-99 I6 would fit the 2000 year engine. I am pretty sure it will bolt up to the head. But will this headder fit inside the available space. Im thinking there the same.

The banks part numbers are as follows.

51304 1991-1999 I-6 Single flange.
51306 2000-2006 I-6 Double flange.

Thanks for the help.

I have the banks header for my 2001. I love it.
If you got the time and money it will work one way or another.

Thats not really the answer I was looking for. Thanks Though. Do you have a single or double flange headder? Im hoping the earlier one will fit with no modifications to the intake manifold or anything else under there. Thanks.

I just called Banks and they said that the headders should interchange. The head flange and the gasket are the same and the collectors are the same size. Plus they said if it dont fit they will exchange it. So Ill find out in a couple of weeks if it fits or not.
