Hi,
nobody helped me in other threads, so I open a new one.
How big are:
-the inlets of the HR Y-pipe and how big is the outlet?
-the inlets of the DE Y-pipe and how big is the outlet?

Thanks,
Alex.

 

its the same on both counts

 

dont think so. but what inlets and outlet does they have then? 2x2,25 inlets and 1x 2,5 outlet ?
Alex.

 

The are not the same. But no one has really measured them.

 

This thread is your best bet

very good, thank you.

 

I have a HR Y pipe on the way - I'll measure the ID's and OD's when I get it. In the thread referenced above from G35 Driver, DaveB stated that the inlets are the same, but the outlet is 2.35" ID on the DE and a full 2.5" ID on the HR.

 

so I think the inlets must be 2,25 and outlets should be 2,35de and 2,5 hr. but im excited on your post chris!
so this is a way much too small for my twins. i gonna want to stay with my single because im very happy with it. 2,5 inlets and 3" outlet should be good for me.

 

I meausured the stock DE Y pipe today. I used a tape meausure made for outside diameter measurements, which gave me a very acurate read. I used a regular tape for the inner diameters.

Inlets
2.25" OD
2" ID

Outlet
2.5" OD
2.375" ID

I'll update with the HR measurements when I receive it, but I have a feeling it will be the same as the DE.

 

I can post up pics of the Stock HR Y-pipe on Friday. I'll have the measurements.

 

could you also give us the all in all length and the bright of the y-pipe?
thanks,
alex
