SUZUKI GP100

Hello im new here, i have just brought a Suzuki gp100 and an looking to tune it. i'm finding it hard to fine performance exhaust's.
iv found a nikon exhaust for the 'Yamaha rxs100' and the exhaust mounting looks the same, so im wondering if the yamaha exhaust would fit my suzuki?
does anyone know if this will work?

Thanks charlie.

should fit ok wont make it any faster just sound better also it could make your insurance void unless you tell insurance company its modified
