fz free flow exhaust, with no drone
I am currently running Tommys free flow , I have tried running a home made free flow mod which resulted a drone attached to vibration that I could feel under my feet, 2 days of that crap was just punishment ,so back to tommys ffe and a few ducky's to parts pak for a another oem replacement
-can anyone say that the ffe with thru hull ,has a drone and vibration
-I am trying to get the performance of a free flow , with out the noise
- has anyone been able to come up with better idea than Tommy (no offense Tommy)

I had the Riva FF on my SHO and it droned like crazy, so when I bought the FZR I went straight to the thru-hull. The big problem is that it echos in the pump tunnel. The thru-hull drones a little but not nearly as much as the traditional FF exhaust setup.

True, the rear exhaust gets rid of the drone, but it's MUCH louder. It's not noticeable above 40 mph, but at low speeds it's annoying as hell on long rides, more so than the drone from the FF IMO. Also, at slower speeds in rough water you get a wa-wa-wa sound as the outlet gets partially submerged & comes back out. After installing it, my wife & I did some cruising on the SHO riding 2-up, & with her on the back I have to keep my speeds down in rough water. It was brutal, & at the end of the day she was bitching at me because she said she couldn't hear out of her right ear. I'm going to try the resonator Ross used to see if it quiets it back down again.
It kinda depends on how you use your ski. If you go out & rip around your local lakes & rivers it's fine, but if you do 100 mile rides where you're going to deal with rough conditions, speed restricted areas & no-wake zones, I'd think twice about going with the rear exhaust, especially since once it's done there's no going back.

Why does anyone bother with anything other than a modified stock exhaust? Is there that much of a power gain, or is it just for noise?

Tommy's still looking good, but with Tommy's I lost a little low end compared to the free flow, I wonder how it effects the topend (Tommy's ffe)
