Exhaust Downpipe Rust

I recently bought GT 125 R that was being unused for a long time. I was changing oil and saw that downpipe is really corroded. It appears that around the actual pipe there is another one which broke as you can see on the pictures. Can I just cut the broken layer around the actual pipe and secure the one inside ? Or do I need new downpipe ?

Whoaa….. I say that looks really bad!
Do you think you’re able to get a exhaust shop local or a garage to extract the “likely” seized bolts at the engine ports.
Or try , if you dare , the front engine is usually prone to rusty bolts & pipes sometimes from salty muddy weather!
The reason i say this is because it’s easier to remove the exhaust system off the bike, then get a way to get it welded (costly) / sleeved up again.
i have seen people also spray a lot of VHT black paint that is supoosed to be weather resistant. Then they wrap it up with exhaust wrap all over.
More than likely you will be looking at fresh studs & bolts anyway! – Stainless is the way to go!
The stock hyosung exhaust pipes have 1 big outer shield (which is whats corroding away) & 1 small “inner” exhaust gas pipe that the engine uses…)

Any recommended place to get SS ?
Do you mean stainless exhausts?; I’d say Black Widow UK definitely, some folks have scorpion pipes fitted on.
As for bolts, a local bike shop must have a tray of exhaust bolts as they are common replacements for rusty ones…
Stainless = only the “threaded” stud can be found in stainless form too.
Not stainless = the original hyosung TALL nuts , for these sand them down and apply vht paint, when you’re cleaning the bike on a regular , a tiny dose of acf50 on the bolts and the pipes, that will burn off , but leaves a tiny film over them. Another way to avoid more weather attacks on the pipes.
As for the tall nuts, only hyosung seems apparently to be the only source. So dealers have to order them in , you may find used “hyosung exhaust nuts” on ebay that aren’t too ruined, may still have some life in them. Expect to repaint them or treat the surfacing rust
Hope this info helps!

Hi I was looking at exhausts. However contacted backwidow and they direct me to the fuel injection type exhaust however mine is an 09 carb model.
I am struggling to find a new exhaust for mine and mine is dead it’s been welded however badly corroded and needs new system. Have a new silencer on it max torque can.

Hey!,
I wouldn’t panic – “All years” of Carb & EFI vTwins of GT250R & 125R use the same pipes. Same fitting too.BlackWidows makes the pipes for Carb & EFI , yes correct , but they will send you a “blanking” bolt. Call them and ask them to make sure a blanking bolt is included.
Refer to the image below:
Having said, this would also be the case with Scorpion or MTC UK exhaust companies – They must send a blanking bolt for carb models , if they send you EFI pipes
If you need a stock/standard pipe system that is in a good nick , please call “Startrights Leeds” & tell them this:
Looking for a standard exhaust system for GT125R , in used condition – Marcel says you have the orange hyosung for stripping (I sent you)
They will discount it for you & post it direct. 👍

Good luck, welcome to the forum!
