Explanation Of Exhaust Pieces From Turbo Back

[ossie cossie]

Can someone please explain what the different parts of the GT-R exhaust system are, i have just got what i thought was a midpipe, it was an easy fit just removed the original piece on the car and this just bolted on. It is just a stainless Y type pipe so is it a Y pipe? Where are the cats on this car? pics would be good.

will be asking more questions as time goes on.

Regards

Tony.

very straight forward on the gtr

headers/exhaust manifold -> downpipes -> midpipe/y-pipe > centre pipe + muffler/cat back

oem has cats in downpipes and midpipe

OK i have fitted a Mid/Y pipe, the OEM one weighed about 16kg and the Y pipe weighs 7kg, now i am assuming it only has cats in the standard down pipes, Is that correct. Looking at intakes and K/N type pod filters next. Any sujestions? also flashed it with the cobb stage 2 and TCM reflash stage 2 LC as well.

If you've only changed the midpipe, then you're left with stock downpipes and stock catback/centre pipe, so both ends of the midpipe are still stock.

Gotboost 3" intakes with the pods, & grab a set of 2012 inlets to sort you out. Go to GTRLife in the US and import it

Then go get a custom tune

3" intakes are hard to tune with maf - no way an off the shelf cobb map will run right

best to stick with a 2.75" intake with a maf based custom tune

No it won't but a custom tune will sort it, and be better off for it
