Recommend exhaust for standard piaggio zip 50

Hi I am new to this forum and it has been recommended to me, I was just wondering what the best sports exhaust for my standard piaggio zip 50 is. Around the tt exhaust are (was considering a leovince tt exhaust) Opinions thanks

 

Technigas trek , technigas triops - leo vince tt they would be your lower end prince ranged pipes.
then your heading up into the stage 6 pro pipe and the likes .
very top end pipes are the yasuni c16 costing a arm and a shed but producing the ultimate in tuning preformance.

i have just blown a leo vince TT and replaced it with a technigas trek.

i found the leo vince a bit of a pain to tune the variator to , its got a short powerband spread of around 800-1000rpm so your really struggling to get the roller weights perfected to suit the pipes powerband spread.

the trek is more forgiving on tuning of rollers its powerband spread is wider 900-1400 rpm so theres more leeway for a newbie to make a mistake and add slightly to heavy rolelrs but it not affecting the scooter in a really nasty way ( ie just total lack of pull and a real slow take off speed and speed build up to a point the pipe can take over )
