Doppler Exhaust S3r Evolution Reviews How Fast Will My Moped Go?? ?

How Fast Will My Moped Go?? ? - doppler exhaust s3r evolution reviews

The moped is a Black Aprillia SR 50 (blue rims), 09 plates.

I'm in the form:
- The Doppler S3R exhaust restricted 50cc - Scooter 70cc Power Pipe
- Air Filter Polini Evolution
- Made of polished aluminum Doppler Boost Bottle
(I think MOTOR DRIVE RESTRICTED)

To think, I will add:
- Black Renthal bars
- TNT Multi-Function Tachometer
- Doppler Grips (black and gray)
- The effect of carbon fiber - Indicator Kit
- Buzzetti Side stand - Black
- 2 Blue Neon Lights
- Cock Pit 12V switch On / Off - Black Cover trigger (for neon)

How quickly and how do you think?

Thanks
