y piece gsa

[twincam]

Hi,will a y piece on my 2010 gsa make much of a difference.
It gave a boost in power to my 1150,does a y piece have the same effect
On the twincam 1200??

Yes mate, it will give you a small but noticeable boost in power especially low down.

It's not Y piece on the 1200 and you change the headers from the cylinder heads to just behined the silencer
