Personally speaking myself and my wife run racing and track day events at Lakeside.. Included is Minimoto, Minitard, Scooters, Postie Bikes, Buckets (Moriwaki's and the like) and Supermoto..
All the 2T bikes except the Scooters have had to modify their pipes and or airbox's to reduce the db output..
This next picture is a simple slip-on muffler that was made up for the sole purpose of reducing the db output.. This slip-on knocks anywhere between 5-8db's of the overall reading, certainly does not require a trailer to carry it around and most definately does not reduce the power by over a half..
This is a Minimoto one but I also run the exact same design on my Moriwaki, only difference is that the Mori one is wider in diametre..
There is a ball of coarse steel wool placed inside the slip-on which gets pressed upto the end of the original muffler..
Now from personal experience running all my bikes with and without the slip-on, there would only be a 1hp drop at maximum, this test has also been performed side by side with other bikes to guage if one out performed the other, which it didn't..
So back to my original post..
1. I have been told by someone that by restricting the exhaust system to control the noise output on a bike will in turn overheat the motor and destroy it.. Yes/no?? EDIT: Also from riding and testing I have not noticed any increase in temp on my gauge whilst riding.. I only ask this becuase some apparent guru says otherwise..
2.I have also been told by someone else that by creating more heat will help with the combustion of the air/fuel and in turn create more power.. Yes/no??
3.What about heat wrap.. Is it a bad idea to wrap a 2T exhaust in heat wrap??
4.Is it a really bad idea to run one of the custom slip-on's on an NSR??
All question's are in regard to NSR's..
Oh and 80XAR, I've got stock airbox's although I'm currently not running them on the NSR's and although I have stock pipes I'm getting TYGA pipes in the next few weeks..
