Y pipe otions

christian370z

Just measured my stock Y pipe for you guys... My measurements for the inlet and outlet diameters of the stock Y pipe are as follows:

Cat to Y pipe: 1 3/4" for both inlets of the OEM y pipe
Y pipe to axle-back: 2 1/2"

Hi: lots of talk on the pro's and con's of "Y" "H" and "X" pipes. So what's the pro's and con's of running a true dual set up from the cats back.

Here in the UK, am limited on what manufactured after market systems are available without importing, systems that are readily available here are Nismo S tune, Invidia Q300 and systems made by Janspeed, Cobra and Scorpion.

So was looking at going down the custom fit road but have not seen much info or remarks on true dual systems. Any help or comments on this type of set up would be a great help

Thanks guys

Jordo!

In short, a lot of noise and a loss of low end torque, although it might pick up some top end. The Y and X improve scavaging and maintain better low speed power while also picking up some top end as well.

I believe the H functions similarly to a "true dual", but the cross link allows for some sound wave equilization which keeps the tone from getting overly loud.
