I have UFO with 4 megaphones. It seems a bit loud with the 2 1/2" tips. If I switch to the 1 1/2" tips would it make any difference in jetting or performance? I would imagine the four small tips would outflow the engine anyway. I wonder about the 2 1/2 inch core slamming into the 1 1/2" opening...
Actually you are right. They are smaller in that pic. That was taken when I looked at it the first time a while back. The caps on it now are 2 1/2". I will try to get the small ones back from him. That will help. How will smaller caps affect performance?
Thanks, I did pull one off and there is white fiberglass packing. The original owner must have tried too.:hmmm: I remember him saying something about different end caps but it was in one ear and out other because I was so exited when I picked it up:biglaugh:
I just bought myself an 06 Max with only 3600 miles on it with a bunch of aftermarket goodies. My question is it has UFO exhaust that expands back from the 2 to 1 collector under bike to 2 megaphone cans. It is crazy loud!! Does anybody else have something like this? Are there smaller aluminum...
