Bnr34 Dump Pipe Difference?

[Phantom Snail]

Hi guys ..

hks online and tomei online have 2 different part number listings for rb26dett dump pipes ... apparently 1 is to suite the r32 and r33 which has only 1 hole on each dump pipe for the sensors .. however there is apparently another 1 which is to suite r34 which is supposedly different ... having 2 holes on each dump pipe .. so 4 holes all up for 4 sensors?

Does this sound rite to you guys? That the r34 gtr dump pipes are different and have 2 extra sensor holes over the r32 and r33 gtr dump pipes?

cheers

for the exhaust sensor for the MFD

for the exhaust sensor for the MFD

4 sensors doesnt make sense to me ... because 1 would be oxygen and the other would be exhaust temperature .. but what about the extra 2 holes left over? what are they for?

[ylwgtr2]

one oxy sensor for each dump....and one for the mfd

As troy said - each dump has a O2 attached.

GTR's have TWO. They are also R34 specific... R33 and R32 all have different O2 sensor's.

How much power etc are you looking at?

R34 GTR dumps have run 380rwkw without a problem many times... IMO you dont really need to upgrade and can spend the cash on other parts for more benefit

So it is correct that r34 gtr's have 4 sensors? 2 for oxygen and 2 for exhaust temp mfd?

Im fitting my 34 dumps soon, should fix my boost creep problems!

I dont know why any R34 owner would want to change these out!
