Metrakit pro race 2 exhaust with Malossi Sport cylidner , help please !

Hello , i have yamaha aerox with setup like this :

Malossi sport 70
original clutch with malossi black springs
malossi red contra? spring
polini speedcontrol with 5.0g rollers
dellorto 21 carb + malossi e5 powerfilter

and some guy offered me a pro race exhaust with very good price , so i have a question does this exhaust gonna be too powerfull for malossi sport , or it gonna work well ?

( working out of malossi sport rpm range or something like that ) ?

I am using a friends malossi racing exhaust on my mhr replica
(70cc aluminium with dual-ring piston) and a 21 dellorto and I can say I saw more performance than my rs2

Although the carb nice much work it is faster so I'd say try it first but i think it will be better....

not really good to use prorace exhaust with malossi sport kit, port timings don't go well with a high rpm race exhaust, you should get an MHR kit at least or a Yasuni R pipe.

I have tried Polini Sport cylinder with Evo 10 exhaust and worked amazing.So much power from so weak cylinder. I was impressed, but use the best oil you can get !!!
