all years '94-'01 exhaust manifolds (i.e. stock "header") are interchangable right? no differences?

Thanks in advance

 

nope

 

as in no differences or "nope" as in they are not interchangeable?

someone knows this!...to be more specific i am talking about the GS-R...

Just between GS-R's, are they interchangeable. I'm not 100% sure on the '00-'01 GS-R's tho.

 

for gsr's....'94-99 are interchangeable and '00-01 are also.

rs/ls/gs and gsr are not interchangeable for any years that i know of...

 

They have the same flange but are different lengths.

i thought the obd2 teg's -96up -had a o2 sensor on the header? - i know my 94 don't have any sensors on it

 

not to mention oxygen sensor placement

 

that's why i said that they aren't interchangeable, since you would have to get a different catback exhaust for it to work.

and yes, the obdII manifolds have an o2 bung in them. you can use an obdI mani, but you would have to have an exhaust shop weld in an o2 bung for it to work.

 

ok...sorry to bring this up again, but i am needing to buy one asap. so this is what i have:

all GS-R manifolds '94-'01 will fit
'94 and '95 manifold do not have O2 bung

i have a '99 GS-R...if i want plug and play characteristics i want '96-'01 manifold and A-pipe...correct?

please help

 

jeezz...someone help me out...don't make me go to the ITR forum...

 

i don't want to make a purchase that i will regret because of lack of information... please answer my question!

 

Just to be on the safe side, you'd better narrow it down to '96 to '00 GS-R's.

 

94-95 OBDI GSR's have one O2 sensor....I don't remember if it is in the a-pipe or cat

96-01 OBDII GSR's have two O2 sensors....I believe they are both in the cat...I know for a fact that the 96-99 ones are both in the cat.

94-99 GSR exhaust manifold ARE interchangeable because they are the same length and use the same length cat.

00-01 GSR exhaust manifolds and exhaust are a different lenght...so it is not interchangeable unless you have the cat and exhaust from a 00-01 that you will swap into an earlier year.

Just look at any header manufacturers site (www.dcsports.com) and it will list part number for specific years...it should answer your question.

 

Its in the cat. The A-pipe is shorter, the cat is longer, & the O2 sensor is pretty much in the same location as far as the floorpan of the car is concerned.

 

Right. Just before the collector, no cat 02 bungs.

96-99 have both in the cat, 00-01 have one in the cat and one in the header, a la 94-01 LS/GS/RS/ITR. Same header.

Right. Every 94-99 GSR header is interchangeable.

The 00-01 cats are shorter, so like he says, you would need either the cat and extended exhaust, or a custom cat to fit. 00-01 GSR manifolds are exactly the same as 94-01 LS/GS/RS/ITR and are completely interchangable with them.
