Benelli 49x Eghaust change help..

Hello ,

I own a Benelli 49x and am thinking of changing the exhaust from the original one (deristricted tho) to a giannelli pipe..
A little techical info about the bike

Malossi Belt
6g Rollers
Yamaha Race Variator
All restrictors are removed
Catalyst removed from the original pipe..

What giannelli will fit my bike? Will it need special mods to fit? Is it gonna work ok?
I need help asap..

Thanks..

 

What engine does it have? Most likely to be minarelli or morini, both are tuneable engines

 

its a minarelli engine mate..

 

i work for a benelli dealer you should call me because i can speak to them and get the right advice from there tech team and give you a list of performance pipes
