If you cut the “4 bolt” fitting , like below:
Then you can find any 51mm exhaust muffler , We here in the UK recommend,
- Black Widow Exhausts
- MTC Exhaust (Max Torque Cans)
- Lextek OP1
- Lextek (other full size 51mm)
Also , DB killer is important, because the vtwin does not like it when it is too free flowing , it needs some gases to stay inside, it helps with torque a little bit.
It is possible in your country you will the companies above shipping to you via Amazon or Ebay as they have their own websites too on the internet too.
If you want to keep the 4-bolt fitting, we heard good recommendations from USA for the company called “2Brothers /TwoBrothers” exhausts who make them specifically for the GT250, they look good! (But a little too expensive for some of us in UK haha.)
AliExpress Mufflers = I would avoid them if i can help it, they turn to rust and it’s nothing inside but a shell of loudness. These cans make your bike sound like a hair drier or lawnmower, the “crispness” of sound is missing , you get a “better sound even with DB killer fitted” using the companies above
SHORTY (Stubby Cans) = I don’t like them but that’s just me, i’ve also tried to love them but my bikes hate them to due to “literally no gains” but hearing loss. lol
Regards
PS. as you have an EFI model with Lambda sensors in the pipe => The “DB Killer” and “Full Size Muffler” is important for the long run.

Looks good to me!
Just make sure it has a DB Killer included, the EFi will cope with it and it was made for the Hyosung 250R specifically. I think Hyosung racebikes in New Zealand use those cans (some are EFI too)

Can you rip that pipe out when you cut that flange off?
The inner pipe inside is the real exhaust, the outerpipe is a welded 2nd layer (also acts as a shield) , it doesn’t affect power.
