i just realized that there was a dynoport racing silencer can on the sled i bought and i am wondering if it actually makes any hp , this silencer is on a 1997 vmax 700sx.
I had one for about 5 years on my xt700. I liked the sound, but didn't really notice any hp inprovement. I had to take it off due to NH exhaust rules(i got a ticket last year).
