    Riva Thru Hull Exhaust ** VIDEO ATTACHED**

    This thing looks great. I really like the fact that using this exhaust gets the hot exhaust pipe/hose away from the RR intercooler. I'm hoping this will make a difference in performance.





    Here is a short video showing what this thing sounds like

    Very nice Jerry....oh and I have to say - kudos for having the clamps aligned

    I don't see why you won't get a power increase.....especially with the head work. Anytime you can increase the exhaust flow you should increase power and the stock setup is extremely restrictive.

    Jerry, that looks nice. I thought you already had your exhaust exit like that I thought I seen pics a while back? Good Idea for heat reasons, plus the exhaust fumes, water and whatever woun't be hitting your pump. alot of ++'s eh? How much?

    Jerry, does the Riva make the same echoing noise as the your old one at about 3000 rpm's? That noise is piercing. I would think not being that it's not coming out in that pump area.
