Is this what I need
 

Installed new EMI exhaust and when connecting my silent choice diverters to the y-pipe the hose it to short. After doing a search I found this hose that is longer than the merc factory one. Is this what I need? I tried 4 inch round hose, to big, 3.5 to small. Hoping someone has used this before and can tell me it is what I need before buying. Thanks in advance.
