Default GSR sounds raspy when the WG opens? because open dump tube?

I notice that when my wastegate opens and I'm in vtec that my GSR sounds very raspy. Is this because I'm running an open end dump tube? How can I fix it?

Run closed loop. It's the only way to kill that lawnmower wg noise.

Is there a noticeable difference in performance?

minimum distance for the dump tube to run separately is 18", before joining the main exhaust.

At the risk of sounding dumb, how does one go about "closing the loop" ?

you rejoin the bump tube into the main exhaust.
18" down the road.

Has anyone ever tried attaching a "mini" muffler to the end of the dunp tube? I wonder if that would quiet it down a bit?

if you want it quiet, just route it back in the exhaust.

I think my open dump tube sounds good. Doesnt sound like a lownmower to me...i like it
