Reply To: Hello from Perth, GT250R Rider
Hi Marcel,
Thank you for the welcome and suggestions. I’ll definitely be taking a lot of photos/videos along the way, until I hit that penultimate track day.
Overall I don’t want the modification of the bike to cost be a lot. Mainly because of a) it is only a 250cc and b) I’m doing the work myself and I’m learning. It’s a project to get me into modifying and improving bikes. For the exhaust itself I’d say it would be no more than AU$200-$300 at this stage. Mainly as it would be my first modification and I’d use it as a starting point to continue modification on my bike. Essentially coming back to the exhaust once I’ve upgraded everything else. My thought is that if I start with an upgraded exhaust to get rid of my heavy existing muffler set up then it gets me off on the right track. After I can then start to tweak the carb jets, the air filter and other parts of the bike. I think it would be better use of money and time to do it that way than spend $1000 on a single exhaust system to then restrict myself on other mods. In your opinion do you think that this is the way, or should i just start with the K&N filter and upjet option thats in the shop? Then work on the coils and regulator and finish with the exhaust.
I’ll take a look at the Black Widow systems and see if they tickle my fancy.
I don;t know anyone personally but I have seen custom exhaust shops around the place and have enquired about a full new system which would be in the ballpark figure of $1000. Out of curiosity, would you have a schematic of the exhaust system on a GT250R? Only because I’d be interested to see what restrictions are in place within the pipe system. Then I can gauge on whether its worth doing mass mods to the existing or scrapping it and starting from scratch. Interested also in your comment regarding cutting the cat box, do you have an image you could send through for me to look at?
Not too sure about noise levels in my state, but I almost want to just run the gauntlet and see what happens if i just put an optimised unrestricted (or at least as unrestricted as possible) set up on. Will need to check on track noise levels though.
I would love to install some form of motogp style exhaust system, one pipe per cylinder but not sure how realistic that is. Seems like it would be too technical to start designing something that may reduce my power rather than improve it.

Bike without stock muffler which I like the look of as the short exhaust seems more aesthetically pleasing.
