RE: Extreme Flight RC 104 inch 100cc Yak-54 sneak peek
Galen, the Yak has a tunnel that will accomodate both canisters and tuned pipes. Tuned pipes are an excellent idea for a twin. The ES carbon pipes would be really trick and weigh just a little more than the stock exhaust, not to mention being whisper quiet.
I just sent an email to ES Composites about producing a pipe for the new 85cc. Anyone else interested please send Ed an email and lets see if we can get him to do it.
