Hi

I'm needing a new exhaust for my TS 125, and I've seen that Ost 2 Rad do a sports exhaust to fit. Has anyone on here fitted one? Does it go straight on or do you have to make modifications? Is it going to cause problems for my engine?

as with all sports exhausts, you will need to make your fuelling match to make it not run likea sack of shit,
ie up jet with a more open airfilter.

that said on 125 2t you are never gonna get much power, and adding sports exhaust will ruin your fuel economy
ie will going 5-10 mph faster be worth less range and more money into the tank a week?
