Upgrade the vehicle's workhorse?

Hi guys; 106 I have a 3-door xr hasn't filled the month yet :) the car is very serial but it seems to me that it is struggling even on the ramps which are light on the ramps. There is no play on the vehicle. For example, will the abarth exhaust benefit the vehicle? because of speed and sports spirals? thanks for the answers

the most logical is the direct air filter, the exhaust and the chip tuning to support them. You get 7-8 hp with the chip. There is not much change in the final speed, but the car will attack even more.
