Title: Slip-On Exhaust Recommendation
Post by: Super Scooter Guy on April 27, 2015, 09:59:12 PM: Anyone have any recommendations for a stronger grunt sounding exhaust for the 500? I want my bike to be heard.

This is what the RS3 sounds like, deep rumble. Would sound even better on the 500.

It fits in the rear so the muffler does not have to be removed to change out the street-legal for the racing one. The racing one sounds like a big bad thumper. A little too loud for my overall comfort level. And I wasn't sure about the back pressure thing, so I mostly run it with the street legal.

It was expensive, however, I got it direct from Zard lab in Itally and the euro was down against the dollar. I like the Zard.

Even a small amount of air leeakage will cause this popping.

Will check this out, thanks
I know there's leakage at the end of the muffler and the former owner of the exhaust drilled holes in the silencer.

Post by: guile on June 18, 2015, 06:16:11 PM: I had the holes closed by a welder. Unfortunately still crazy popping

Post by: guile on October 28, 2015, 03:49:00 PM: I put the original muffler on. I rode about a year with the MIVV muffler, but nothing but trouble. The small increase in HP isn't worth the trouble.
I think the X is already optimally tuned. I would only recommend a different variator (Malossi, about 20.000 miles now)
