dynoport 2 into 1 pipe with 2 silencers . 1 silencer is the origional dynoport silencer , the 2nd one is a custom Aaen performance spark arrestor silencer with a turndown . I had the 2nd one built to make it legal for ridingon state land and at the dunes . it is a kirzman style spark arrestor , not a screen type that can clog and hurt performance . I really like the 2 into 1 pipe , it makes the bike super easy to ride in the tight woods or trails .with this pipe it pulls real hard in low to mid range and still revs out to a good top end ( about same as stock pipes ) best part is it uses the stock banshee jetting ! , actually I ran mine leaner than stock banshee jetting ! great all around pipe , but I have lost all my trail riding buddies ................. so I guess I have to build a competitive duneer/drag motor now , and this pipe will not cut it . heres a few pics of it , its still on the bike until someone buys it .lol one pic has the old dp silencer , the silencer with the turndown is te Aaensparky one . I would like to get 240.00 shipped for everything , both silencers , and the pipe to the 48 states ak and hi add 15 bucks . .
