I have a GT125R 2015 and the exhaust end can i have ordered is an sc-project crt, this exhaust end can is straight through, what would you recommend? should i get the 90 front and 92.5 rear main jets or bigger. also the exhaust can has no baffles with it.

You will loose the intial torque that you want when taking off, the baffle should be inside , and a baffle with a hole size (inside or out)ย  ofย  a 10p size, is a good sized hole.ย  HUGE HOLE baffles are almost pointless but still better than without ๐Ÿ˜‰

Fuller size cans do better than shorties on any 4T bike if im honest, ive found out the same on both 125 n 250 hyosungs,ย ย ย  No baffle = it will scream more to get going at the same speeds sometimes.

90 and 92.5 is enough for 125s.

Then follow this tutorial belowย  (it improves ur 90 n 92.5 in top gear, also 4-7k rpm flat spot fixing)(so extra mod)
