Help installing rear Termi header on S4RS

[DucRS]

 After running the ExBox exhaust for 4 yrs I decided to go for the Termi's in search of more power and better sound. So, as I was in the process of installing A full Termi system on my 07 S4RS, I found it impossible to install the rear header onto the cylinder due to it's increase in diameter from the stock one without removing shock components. 
  If anybody has any advice feel free to chime in.

Thanks!

IIRC, if you have a large friend sit on the seat, it'll move the suspension parts enough to allow install.

Make sure to get the plan worked out ahead of time, lest your friend change position while your fingers are in a risky area.

A search may yield real FHE....
