If I de-restrict a Tecnigas Silent Sport exhaust will it sound louder?

Can anyone tell me if I de-restrict a Tecnigas Silent Sport exhaust will it sound louder? And how much more power would it give?
Cheers,

Hi did you de restrict it in the end? I've got the same exhaust
Thanks

 

I "didn´t really" , what I did was, I drilled out the washer at the cylinder end by a about 5mm. I don´t really think this changed much but I suppose every little helps somewhere down the line. Sound wise, I can´t hear any difference.

 

Ok, did it improve the speed or acceleration? I think mine has been removed but still seems restricted is there another restrictor?

 

Hi Jesse, I can´t really say if it has given me a better performance because I´ve been battling with my variator and belt for a while now. I changed the original variator because it showed major sign of wear and then I was sold one which turned out to be a standard variator for a 125cc and now I´m using a cheapish one I got off Ebay. The latest one seems to be working well although I have to fit a new belt because the last one put way too much wear on it.


In saying this though, I can easily hit 50km/h on the flat and nothing other than the exhaust has been fiddled with (I still have the restrictor washer on the variator and I´m actually using slightly lighter rollers which should give me better acceleration up hills). Hill tackling is still the thorn in my side but hopefully with a new belt fitted and maybe even lighter rollers, 5,75g instead of 6,0g, I´ll see an improvement. The stock weight is 6,5g so I´m just trying out different weights for at least 200km so I can get a bigger picture in different weather conditions and driving both long and short distances both in the countryside and city.


Some exhausts have a baffle tube inside the actual exhaust itself, if you search on YouTube then you can see what I mean.
I read somewhere that the exhaust exit port could also be made bigger but I´m not taking any chances doing this simply because the police over here look for this kind of thing if and when they stop a scooterist. The fines are hefty and you can loose your car license if you´ve modified your 50cc scooter in anyway.
