Bike Model = : Gv125S bobber
Hi I’ve been looking at a new muffler for my bike to make it louder and more deep. I’ve been looking at a megaton muffler just wondering if anyone is familiar and if it drop performance. Or if anyone has any other suggestions for brands.

This one is would do better that the one you mentioned and road legal too , i focused on cans that are least 400mm long https://www.lextekproducts.com/part/SA1
Confirm with your local fabricator to make you a short link pipe to join it to your narrower downpipes
Blackwidow remain as my personal #1 brand
https://www.blackwidowexhausts.co.uk/black-widow-silencers-239-c.asp?_=&f-SILENCERLENGTH=f-400mm&minprice=104.99&maxprice=194.99Hope that helps.

I have the same bike and also looking for the muffler. I plan to wrap the exhaust pipes + install better muffler.
Megatone has db killer which you can adjust (3 screws) but overall it’s loud
I was also looking for this one: https://www.silverstonemotor.com/en/silencers/13924-ixrace-hyosung-bobber-125-300-2018-2023-gamme-custom-black-exhaust-silencer-ag4022sb-not-approved.html
It’s matching the bike very well and it’s not that loud…

Ye I’ve had a look at both of them. The megaton seems Chinese made so might loose power and be not that reliable. And the other one is way out of my budget
ive been looking at this one

Here is an EU company who does OK for exhausts (personally i used them on a non-hyosung branded bike, and it was OK as long as the baffle was inside, that was 20yrs ago lol) so who knows if they improved their tech ?
https://ixil.com/en/16-hyosungAlso despite them making slip-ons for Hyosung , but no news yet on GV125-S , so your best option is to browse their page and look for a long & narrow can that’s about 400mm (long the better!) but don’t go under 350mm and should be as wide as your original one , because if its too wide (not a bad thing) you will need the bracket to extend it away from the swingarm + a 75 or 60 degree custom link pipe to connect back to your exhaust pipes. (then another link pipe, so it makes an S shape to keep the sleek look of the bike ie. [can___/—-engine]
The _ and / and — are just a simpler way i can visualize what i mean )Scorpion might be OK, there is other EU exhaust makers (usually the EU is more strict with exhausts being road legal for some countries due to Euro 4-6 laws , here in UK it’s not really a big deal unless the baffle is missing then it will fail for “exhaust too loud” unless it is designed to be loud by OEM (ie. really old harleys)
I would suggest OEM 2025 factory harley cans but they weigh too much and you loose power (adding extra weight to the bike it doesn’t need) , so you want to stay light and nimble until extra weight is reserved for a pillion or luggage use.

Am sorry to slightly change the thread, but how much does putting a slip-on on affect the bike in terms of hp/torque running needing re-maps mot s or potential engine damage from running lean etc.?
What sort of slipons would cause less issues + not need a re-map?
Ive just got a 2018 gtr650 efi + mite like something a bit louder + lighter but couldnt i just cut/gut or drill some holes easily in the big black stock pipe for starters?
TIA

Lextek , MTC or BlackWidow = make sure the cans are 400mm long (like your OEM one is) and keep the baffle inside (your neighbours will hate you before the bike moans of a missing baffle lol) but it’s a vtwin, it always runs better with baffles in.
BlackWidow gets my vote. UK company and they do make road legal cans , just as Lextek or MTC does too. If not , any can that has a BSAU stamp on it is generally road legal and can’t be disputed at MOT places and engine will be fine.
Messing with your stock muffler on the 650 could be messy but unless you can take the rivets off , remove maybe 10% of what’s inside the can and close it back, it will be more throaty yes.

I just completed exhaust on my GV125S. I used the muffler from HD sportster 883. Highly recommend! No power loss, nice sound, not too loud. The only drawback I see is that the bike gets up to higher temperature a bit quicker. I’m getting two bars on temp display after 15min on idle while previously it was taking a bit longer. All the rest works very well. Muffler is legal and has Euro4 standard.
