Finally get to install the RFY GT EXHAUST Ver 1 (aka GT-Extreme), I also got the Prospeed 300cell highflow cats.
I first installed the exhaust without the center sliencer, then later decided its more civilized with the silencer installed. The exhaust hangers are worned and stretched, therefore the tips are not aligned yet. Need some suggestion on where to get replacement exhaust hangers? OEM or aftermarket?
Was going to install the Prospeed cat as well but found out that my stock cats had 2 extra temp sensors. So I didnt install them. But later I found out that those 2 sensors can be omitted.
So far with the exhaust alone, it sounds pretty awesome nice and high pitched with no drone.
