Want to upgrade my little rocket a little. looking at Yoshimura. Should I do the whole system or just the catalytic converter. not concerned with warranty or USA regulations here in the Philippines. It is a twin cylinder. Thank you
started in 1969 riding motorcross and doing all my own wrenching. This is my 21st cycle and my 5th since moving to the philippines. Have 1000cc in USA but cost to much to ship here with tariff and no parts. The 250 is bigger than 90% bikes in this country. Try the roads here and the drivers,, caribou, dogs, people and no lights on public transpo drivers. I still do my own tuning, dont care about your opinions on upgrades. Only asked for available brands. Didnt get 1 answer on answers. Thank you but none so far answered.
