Any one know if the 2000 OE USDM ITR upper exhaust manifold will bolt in place of an OE 98' USDM GSR upper exhaust mani... using the GSR lower? Just found it cracked and don't have much junkyard light left in the day... IM'd a few people, but got to pick up the kids shortly...

 

can't tell you, might be able to in a few weeks when I try it to see, but can't tell you right now, sorry.

 

...guess I'll be finding out in a few minutes... really wanted to know first so I could go to the junkyard today if I had to...

 

I think it wont work, but I'm not positive so don't listen to me...I'm dumb

 

...looks like the lower flange might be at a different angle???

 

You probably need both pieces. The itr exhaust mani (top piece) and the gsr a-pipe (bottom piece of exhuast mani) will not bolt up.

If you need both for an itr, I have what you need. Then again, I do not know if the oem itr header (both pieces) will bolt up to your existing block and cat.

 

...would have been nice to have found this Sun... I had today off...

 

...found another GSR exhaust mani local...

...thanks to those who replied...
